Building Cryptocurrency Pricing App with Flutter

I’ve come across Google’s new open-source toolkit for cross-platform development recently, and decided to give it a try. You can read about the various benefits here (spoiler, it seems really great), but I thought I would share with you on how to get started with Flutter with something other than their tutorial.

We will be creating a Cryptocurrency Price List app with pull-to-refresh functionality and also to keep track of your favourite Cryptocurrencies.

Prerequisites

I will be using a Macbook with iOS simulator to build this app. Feel free to use Windows machine and an Android emulator.

Before we begin, head over to Flutter and install Flutter and various dependencies. While you are at it, grab your favourite IDE and set it up to use with flutter (we will be using VS Code in this tutorial).

Let’s get started!

In VS Code (follow steps here if needed), search for Flutter New Project to create a new flutter project. Name it crypto_list and let flutter initialise the project for us.

A file main.dart is created, and this will be the point of entry for our app. We will be building the app from scratch, so go ahead and delete all the code there.

This is how your IDE should look at this point.

Creating basic UI

import 'package:flutter/material.dart';

//runApp calls MyApp
void main() => runApp(MyApp());

//Stateless Widget since this class has no state, once created will be immutable
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    //A convenience widget that wraps a number of widgets that are commonly 
    //required for applications implementing Material Design.
    return MaterialApp( 
        title: 'Crypto Price List',
        theme: new ThemeData(primaryColor: Colors.white), //will be used later
        home: new Center(child: new Text('my crypto app'),)); //centralize the text 
  }
}

main.dart

When you start the app, the code will be executed from the main function. So let’s go ahead and create it as above.

open -a Simulator
flutter run

This opens the default simulator used on your machine, and runs the application. Run it and it should show the following

Ok great! You have build your first UI using flutter! It is quite ugly now so let’s create couple of widgets to beautify our app.

Adding widgets

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    //material app widget
    return MaterialApp(
      title: 'Crypto Price List',
      theme: new ThemeData(primaryColor: Colors.white),
      home: CryptoList(),
    ); //use our widget instead of the text previously
  }
}

//creates a stateful widget (data inside will change once created)
class CryptoList extends StatefulWidget {
  @override
  CryptoListState createState() => CryptoListState();
}

class CryptoListState extends State {
  //will be used later to view favourited cryptos
  void _pushSaved() {}

//build method
  @override
  Widget build(BuildContext context) {
    //Implements the basic Material Design visual layout structure.
    //This class provides APIs for showing drawers, snack bars, and bottom sheets.
    return Scaffold(
        appBar: AppBar(
          title: Text('CryptoList'),
          actions: [
            // will be used to view favourites
            new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
          ],
        ),
        body: new Center(
          // body of the scaffold
          child: new Text('my crypto app'),
        ));
  }
}

main.dart

Stateless widgets are immutable, meaning that their properties can’t change — all values are final

Stateful widgets maintain state that might change during the lifetime of the widget. Implementing a stateful widget requires at least two classes: 1) a StatefulWidget class that creates an instance of 2) a State class. The StatefulWidget class is, itself, immutable, but the State class persists over the lifetime of the widget.

Edit our code to be like what is shown above.

What we have done is:

  1. Add a stateful widget CryptoList which creates its state class CryptoListState
  2. Most of the logic will be stored in CryptoListState and CryptoList just creates its State class
  3. build to describe how the widget will look. Here we are returning Scaffold which creates an appBar with title and icons and body with centralised text.

Press r to reload changes or R to hot restart (and rebuild state)

With Scaffold we have infinitely improved the overall UI of our app. Remember we used theme in the MyApp class? It was used to set the primary colour of our app, (and by extension appBar's colour).

Feel free to change it accordingly, for eg new ThemeData(primaryColor: Colors.orange) but we will continue using white.

Making HTTP request to get data

Before we add a list of Cryptocurrencies into the body of our view, let’s first get all the data required for us to continue.

import 'package:flutter/material.dart';
import 'dart:math';
import 'dart:async';
import 'dart:convert';
import 'dart:core';
import 'package:http/http.dart' as http;

Import all these modules we will be using at the top of your main.dart file. Find the file pubspec.yaml and http: ^0.12.0+1 (which is required to make http requests) so that it looks like this:

  1. pubspec is where the packages metadata is stored
  2. dart:async allows writing asynchronous code using Future class
  3. dart:convert allows decoding JSON response
  4. package:http/http.dart allows making http requests
  5. dart:math and dart:code provides some helper functions to manipulate data
import 'package:flutter/material.dart';
import 'dart:math';
import 'dart:async';
import 'dart:convert';
import 'dart:core';
import 'package:http/http.dart' as http;

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    //material app widget
    return MaterialApp(
      title: 'Crypto Price List',
      theme: new ThemeData(primaryColor: Colors.white),
      home: CryptoList(),
    ); //use our widget instead of the text previously
  }
}

//creates a stateful widget (data inside will change once created)
class CryptoList extends StatefulWidget {
  @override
  CryptoListState createState() => CryptoListState();
}

class CryptoListState extends State {
  List _cryptoList;
  //this means that the function will be executed sometime in the future (in this case does not return data)
  Future getCryptoPrices() async {
    //async to use await, which suspends the current function, while it does other stuff and resumes when data ready
    print('getting crypto prices'); //print
    String _apiURL =
        "https://api.coinmarketcap.com/v1/ticker/"; //url to get data
    http.Response response = await http.get(_apiURL); //waits for response
    setState(() {
      this._cryptoList =
          jsonDecode(response.body); //sets the state of our widget
      print(_cryptoList); //prints the list
    });
    return;
  }

  @override
  void initState() { //override creation of state so that we can call our function
    super.initState();
    getCryptoPrices(); //this function is called which then sets the state of our app
  }

//build method
  @override
  Widget build(BuildContext context) {
    //Implements the basic Material Design visual layout structure.
    //This class provides APIs for showing drawers, snack bars, and bottom sheets.
    return Scaffold(
        appBar: AppBar(
          title: Text('CryptoList'),
          actions: [
            // will be used to view favourites
            new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
          ],
        ),
        body: new Center(
          // body of the scaffold
          child: new Text('my crypto app'),
        ));
  }

  //will be used later to view favourited cryptos
  void _pushSaved() {}
}

main.dart

Update the code as shown above. Please read the comments on what is added. Essentially, we have asked our widget to execute getCryptoPrices when the state is initialized. We then perform an async operation to get the data from an api, and set state of cryptoList.

Perform hot restart by pressing R

Great! Our data is available for us to use. We can now generate UI to show this data.

Creating ListView

import 'package:flutter/material.dart';
import 'dart:math';
import 'dart:async';
import 'dart:convert';
import 'dart:core';
import 'package:http/http.dart' as http;

void main() => runApp(MyApp());

      home: CryptoList(),
    ); //use our widget instead of the text previously
  }
}

//creates a stateful widget (data inside will change once created)
class CryptoList extends StatefulWidget {
  @override
  CryptoListState createState() => CryptoListState();
}

class CryptoListState extends State {
  List _cryptoList; //store cryptolist
  final _saved = Set(); //store favourited cryptos
  final _boldStyle =
      new TextStyle(fontWeight: FontWeight.bold); //bold text style to be reused
  bool _loading = false; //will be used later to control state
  final List _colors = [
    //to show different colors for different cryptos
    Colors.blue,
    Colors.indigo,
    Colors.lime,
    Colors.teal,
    Colors.cyan
  ];
  //this means that the function will be executed sometime in the future (in this case does not return data)
  Future getCryptoPrices() async {
    //async to use await, which suspends the current function, while it does other stuff and resumes when data ready
    print('getting crypto prices'); //print
    String _apiURL =
        "https://api.coinmarketcap.com/v1/ticker/"; //url to get data
    http.Response response = await http.get(_apiURL); //waits for response
    setState(() {
      this._cryptoList =
          jsonDecode(response.body); //sets the state of our widget
      print(_cryptoList); //prints the list
    });
    return;
  }

  //takes in an object and returns the price with 2 decimal places
  String cryptoPrice(Map crypto) {
    int decimals = 2;
    int fac = pow(10, decimals);
    double d = double.parse(crypto['price_usd']);
    return "\$" + (d = (d * fac).round() / fac).toString();
  }

  // takes in an object and color and returns a circle avatar with first letter and required color
  CircleAvatar _getLeadingWidget(String name, MaterialColor color) {
    return new CircleAvatar(
      backgroundColor: color,
      child: new Text(name[0]),
    );
  }

  @override
  void initState() {
    //override creation of state so that we can call our function
    super.initState();
    getCryptoPrices(); //this function is called which then sets the state of our app
  }

//build method
  @override
  Widget build(BuildContext context) {
    //Implements the basic Material Design visual layout structure.
    //This class provides APIs for showing drawers, snack bars, and bottom sheets.
    return Scaffold(
        appBar: AppBar(
          title: Text('CryptoList'),
          actions: [
            // will be used to view favourites
            new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
          ],
        ),
        body: _buildCryptoList());
  }

  //will be used later to view favourited cryptos
  void _pushSaved() {}

  //widget that builds the list
  Widget _buildCryptoList() {
    return ListView.builder(
        itemCount: _cryptoList
            .length, //set the item count so that index won't be out of range
        padding:
            const EdgeInsets.all(16.0), //add some padding to make it look good
        itemBuilder: (context, i) {
          //item builder returns a row for each index i=0,1,2,3,4
          // if (i.isOdd) return Divider(); //if index = 1,3,5 ... return a divider to make it visually appealing

          // final index = i ~/ 2; //get the actual index excluding dividers.
          final index = i;
          print(index);
          final MaterialColor color = _colors[index %
              _colors.length]; //iterate through indexes and get the next colour
          return _buildRow(_cryptoList[index], color); //build the row widget
        });
  }

  Widget _buildRow(Map crypto, MaterialColor color) {
    // if _saved contains our crypto, return true
    final bool favourited = _saved.contains(crypto);

    // function to handle when heart icon is tapped
    void _fav() {
      setState(() {
        if (favourited) {
          //if it is favourited previously, remove it from the list
          _saved.remove(crypto);
        } else {
          _saved.add(crypto); //else add it to the array
        }
      });
    }

    // returns a row with the desired properties
    return ListTile(
      leading: _getLeadingWidget(crypto['name'],
          color), // get the first letter of each crypto with the color

        onPressed: _fav, //when pressed, let _fav function handle
      ),
    );
  }
}

main.dart

Update your code with the one shown above. A lot of codes have been added, but I have tried to add as much comments as possible to make it understandable. Here is what we have done:

  1. Replace our Scaffold body with _buildCryptoList. This returns a ListView. Rows are build using _buildRow
  2. _buildRow takes in the each cryptocurrency object with colour. It builds a row accordingly: Avatar, Title, Subtitle and Icon
  3. _fav handles when the heart icon is clicked. _saved contains the list of crypto objects we have favourited.

Perform hot restart by pressing R

Great! You have now built an extremely decent looking UI that contains real data about various Cryptocurrencies. If you could not understand the code, it is okay! Take your time and with enough practice, you will get the hang of it. Else, feel free to leave a comment below.

Adding Loading Bar

If you noticed, when you restart the app, there is a brief second where an error is displayed. This is because when the getCryptoPrices is called, the _cryptoList state, which is used to build the list view, is not set, and thus you get an error until the state is set. Let’s edit the code to show an loading bar until _cryptoList is set.

import 'package:flutter/material.dart';
import 'dart:math';
import 'dart:async';
import 'dart:convert';
import 'dart:core';
import 'package:http/http.dart' as http;

void main() => runApp(MyApp());

    //material app widget
    return MaterialApp(
      title: 'Crypto Price List',
      theme: new ThemeData(primaryColor: Colors.white),
      home: CryptoList(),
    ); //use our widget instead of the text previously
  }
}

//creates a stateful widget (data inside will change once created)
class CryptoList extends StatefulWidget {
  @override
  CryptoListState createState() => CryptoListState();
}

class CryptoListState extends State {
  List _cryptoList; //store cryptolist
  final _saved = Set(); //store favourited cryptos
  final _boldStyle =
      new TextStyle(fontWeight: FontWeight.bold); //bold text style to be reused
  bool _loading = false; //will be used later to control state
  final List _colors = [
    //to show different colors for different cryptos
    Colors.blue,
    Colors.indigo,
    Colors.lime,
    Colors.teal,
    Colors.cyan
  ];
  //this means that the function will be executed sometime in the future (in this case does not return data)
  Future getCryptoPrices() async {
    //async to use await, which suspends the current function, while it does other stuff and resumes when data ready
    print('getting crypto prices'); //print
    String _apiURL =
        "https://api.coinmarketcap.com/v1/ticker/"; //url to get data
    setState(() {
      this._loading = true; //before calling the api, set the loading to true
    });
    http.Response response = await http.get(_apiURL); //waits for response
    setState(() {
      this._cryptoList =
          jsonDecode(response.body); //sets the state of our widget
      this._loading = false; //set the loading to false after we get a response
      print(_cryptoList); //prints the list
    });
    return;
  }

  //takes in an object and returns the price with 2 decimal places
  String cryptoPrice(Map crypto) {
    int decimals = 2;
    int fac = pow(10, decimals);
    double d = double.parse(crypto['price_usd']);
    return "\$" + (d = (d * fac).round() / fac).toString();
  }

  // takes in an object and color and returns a circle avatar with first letter and required color
  CircleAvatar _getLeadingWidget(String name, MaterialColor color) {
    return new CircleAvatar(
      backgroundColor: color,
      child: new Text(name[0]),
    );
  }

  _getMainBody() {
    if (_loading) { //return progress indicator if it is loading
      return new Center(
        child: new CircularProgressIndicator(),
      );
    } else {
      return _buildCryptoList(); //return the list view
    }
  }

    return Scaffold(
        appBar: AppBar(
          title: Text('CryptoList'),
          actions: [
            // will be used to view favourites
            new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
          ],
        ),
        body: _getMainBody());
  }

  //will be used later to view favourited cryptos
  void _pushSaved() {}

  //widget that builds the list
  Widget _buildCryptoList() {
    return ListView.builder(
        itemCount: _cryptoList
            .length, //set the item count so that index won't be out of range
        padding:
            const EdgeInsets.all(16.0), //add some padding to make it look good
        itemBuilder: (context, i) {
          //item builder returns a row for each index i=0,1,2,3,4
          // if (i.isOdd) return Divider(); //if index = 1,3,5 ... return a divider to make it visually appealing

          // final index = i ~/ 2; //get the actual index excluding dividers.
          final index = i;
          print(index);
          final MaterialColor color = _colors[index %
              _colors.length]; //iterate through indexes and get the next colour
          return _buildRow(_cryptoList[index], color); //build the row widget
        });
  }

  Widget _buildRow(Map crypto, MaterialColor color) {
    // if _saved contains our crypto, return true
    final bool favourited = _saved.contains(crypto);

    // function to handle when heart icon is tapped
    void _fav() {
      setState(() {
        if (favourited) {
          //if it is favourited previously, remove it from the list
          _saved.remove(crypto);
        } else {
          _saved.add(crypto); //else add it to the array
        }
      });
    }

    // returns a row with the desired properties
    return ListTile(
      leading: _getLeadingWidget(crypto['name'],
          color), // get the first letter of each crypto with the color
      title: Text(crypto['name']), //title to be name of the crypto
      subtitle: Text(
        //subtitle is below title, get the price in 2 decimal places and set style to bold
        cryptoPrice(crypto),
        style: _boldStyle,
      ),
      trailing: new IconButton(
        //at the end of the row, add an icon button
        // Add the lines from here...
        icon: Icon(favourited
            ? Icons.favorite
            : Icons
                .favorite_border), // if button is favourited, show favourite icon
        color:
            favourited ? Colors.red : null, // if button is favourited, show red
        onPressed: _fav, //when pressed, let _fav function handle
      ),
    );
  }
}

main.dart

Update the code with this. Instead of directly calling the _buildCryptoList in the body of our Scaffold we are calling another function _getMainBody.

In getCryptoPrices we have also set _loadingto true before we make a request and _loadingto false after have completed the request. _getMainBody then checks and returns a progress bar if _loading is true.

When you run the app, you should see a circular progress indicator for a split second instead of an error page we saw earlier.

Pull to Refresh

We have a decently working app right now. Since I have had prior experience building iOS apps, I wanted to see how it would be to mimic some functionalities. One of the most commonly used functionalities is Pull to Refresh.

Turns out, it is actually very simple.

 _getMainBody() {
    if (_loading) {
      return new Center(
        child: new CircularProgressIndicator(),
      );
    } else {
      return new RefreshIndicator(
        child: _buildCryptoList(),
        onRefresh: getCryptoPrices,
      );
    }
  }

main.dart

Replace the _getMainBody with the above function. What it does is, instead of returning ListView directly, it wraps it around RefreshIndicator which allows pull to refresh possible. We then point the onRefresh to the function where we make the api call.

This is why we needed our widget to be Stateful. When the data is changed, either through polling or serve pushes, we want the data to change and UI to be rendered accordingly. If we just want to display the data once for the duration of the application, we can make our widget to be Stateless.

Pushing New View

We have mentioned earlier that we want to be able to view the favourited Cryptocurrencies. So let’s implement that.

//called when the button is pressed to go to the next view
  void _pushSaved() {
    Navigator.of(context).push( //get the current navigator
      new MaterialPageRoute( //A modal route that replaces the entire screen with a platform-adaptive transition.
        builder: (BuildContext context) {
          final Iterable tiles = _saved.map( //iterate through our saved cryptocurrencies sequentially
            (crypto) {
              return new ListTile( //same list tile as what we have shown in the previous page
                leading: _getLeadingWidget(crypto['name'], Colors.blue),
                title: Text(crypto['name']),
                subtitle: Text(
                  cryptoPrice(crypto),
                  style: _boldStyle,
                ),
              );
            },
          );
          final List divided = ListTile.divideTiles( //divided tiles allows to insert the dividers for visually pleasing outcome
            context: context,
            tiles: tiles,
          ).toList();
          return new Scaffold( //return a new scaffold with a new appbar and listview as a body
            appBar: new AppBar(
              title: const Text('Saved Cryptos'),
            ),
            body: new ListView(children: divided),
          );
        },
      ),
    );
  }

main.dart

Implement _pushSaved function we have declared previously as above. I’ve written in comments what is happening. Basically we get each saved item and build a new list and pass it to the new route’s Scaffold.

This function is triggered when:

new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),

in the home screen. Let’s run the app and see what happens.

And of course, cross platform framework would not be useful if we cannot run it on both Android and iOS! So here are the Android equivalent screenshots with no code change.

I believe certain customisations are definitely possible to better suit the native looks of each platforms, such as by using cupertino style widgets but that is not covered in this tutorial.

Final Thoughts

This was my first project I have made using Flutter. I have referenced the original sample shown in the official Flutter page, but have extended it to facilitate my own learning. The framework really feels cool, so I might write other complex tutorials in the future.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.

sksl_warm-up

If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.

flutter_autofill

A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.

flutter_DatePicker

New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:

It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

micro-mobility

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

benefits-micromobility

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

  • Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
  • Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
  • Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
  • Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.
