An Introduction to Flutter

Flutter introduction

An introduction to Flutter.

Preconditions

You need to have Android Studio and Flutter installed.

documentation

The documentation for the programming language ‘Dart’ can be found at: https://dart.dev/guides , The one for Flutter at https://flutter.dev/docs .

The beginning

Create a new flutter project in Android Studio. Select ‘Flutter Application’. Open ‘main.dart’ in the ‘lib’ folder. There you will find generated code which you can delete.

We have to import Flutter and we need a main program:

import  'package: flutter / material.dart' ;

void  main () {
   runApp ( MyApp ());
}

Then we need a widget to start our application:

class  MyApp  extends  StatelessWidget {
   @override 
  Widget  build ( BuildContext context) {
     return  MaterialApp (
      title :  'Flutter Into' ,
      theme :  ThemeData (
        primarySwatch :  Colors .blue,
        visualDensity :  VisualDensity .adaptivePlatformDensity,
      ),
      home :  CookiePage (),
    );
  }
}

So far so good. You always need this code for every new app.

As you can see, we install the CookieHomePage().

Cookie of the Day

You are probably familiar with the fortune cookies that you will receive from the Chinese along with the bill. If you break it you will find a wise saying in it.

We will write an app that shows us a new saying every time we shake the phone.

Widgets

In Flutter, everything you see on the screen is made up of widgets. Widgets generally have an appearance and a functionality.

Flutter has a widget for almost everything. We can (and must) program our own widgets. For this purpose we will discuss some of the existing widgets such as Text, ListTile, RaisedButtonand so on use.

There are also widgets without visual representation. They are used to arrange other widgets. As an example Center, Columnand should be mentioned here ListView.

Widgets are arranged in a hierarchy. To do this, each widget has the property child:or property children:.

In this way we can create a hierarchical layout.

If we program our own widgets, we have to derive them from a suitable widget class and specify how our widget is put together.

This happens in the function Widget build(BuildContext context) which we have to overwrite in our subclass.

CookiePage

Let’s write our first widget.

We want to display a text in the center of our page which contains the saying of the day.

So that our app looks like a real app, we Scaffoldwill use a widget for the basic layout :

class  CookiePage  extends  StatelessWidget {
   @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Cookie of the Day' )
      ),
      body :  Center (
        child :  Text ( 'Should show a cookie' ),
      )
    );
  }
}

Start an emulator under ‘Tools / AVD Manager’ and let the program run.

Data

Next we need data. Let’s write a class that will manage our wisdom.

import  'dart: math' ;

class  Cookies {
   List < String > _cookies; // private member

  Cookies () { // Constructor 
    _cookies = [
       'The good day starts with getting up \ n the bad too' ,
       'Even a blind hen finds a grain' ,
       '42'
    ];
  }

  List < String >  get  cookies => List . unmodifiable (_cookies);

  String  get  cookieOfTheDay => _cookies [ Random (). nextInt (_cookies.length)];

  addCookie ( String wisdom) {_cookies. add (wisdom); }
}

Then we can complete our CookiePage:

class  CookiePage  extends  StatelessWidget {
   final cookies =  Cookies (); // <- new 
  @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Cookie of the Day' )
      ),
      body :  Center (
        child :  Text ( '$ { cookies.cookieOfTheDay }' ), // <- new
      )
    );
  }
}

Select 'Run / Flutter Hot Restart ’ several times .

You should then see various pieces of wisdom.

Collection of cookies

Let’s create another page in which we can manage our cookies.

The upper half of the window should display a list of the existing cookies, below we will display a form for entering a new cookie.

Statefull widget

We’ll create a new widget for this, this time one of type StatefulWidget.

So what is a statefull widget and why do we need it?

In Flutter, all widgets are recreated each time you redraw. If these contain local data, this data is reinitialized each time.

But sometimes we want data (the state) to be retained between the new characters. That’s why we broke in StatefullWidget.

Statefull widgets always consist of two parts, a widget and an associated state.

class  CookieMaintenancePage  extends  StatefulWidget {
   @override 
  _CookieMaintenanceState  createState () =>  _CookieMaintenanceState ();
}

class  _CookieMaintenanceState  extends  State < CookieMaintenancePage > {
   @override 
  Widget  build ( BuildContext context) {
     // TODO: implement widget
  }
}

The basic structure is always the same. The StatefullWidget overwrites the function createState()and returns a suitable state implementation. In the State class we overwrite the function as usual build(...). All variables that are to survive the redraw are defined in the State class.

CookieMaintenancePage

In the CookieMaintenancePagewidget we use against one Scaffoldas a framework. In the middle we have a column that shows the list in the upper part and the form in the lower part.

The cookies are defined in the state variable _cookies.

class  _CookieMaintenanceState  extends  State < CookieMaintenancePage > {
   @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Manage Cookies' ),
      ),
      body :  Center (
        child :  Column (
          mainAxisAlignment :  MainAxisAlignment .center,
          children : [
             Expanded (child :  cookieList ()),
             cookieForm ()
          ],
        ),
      ),
    );
  }

  Widget  cookieList () { return  Container (); } // todo 
  widget  cookieForm () { return  Container (); } // todo 
}

ListView in Flutter

First we implement the list in the function cookieList():

Widget  cookieList () {
     return  ListView . builder (
      itemCount : _cookies.cookies.length,
      itemBuilder : (context, index) {
         return  Card (
          child :  ListTile (
            title :  Text (_cookies.cookies [index]),
          )
        );
      }
    );
  }

Entering text in Flutter

For an overview of how to create a text input in Flutter, please see https://flutter.dev/docs/cookbook/forms/retrieve-input .

We need one in the _CookieMaintenanceState class TextEditingControllerand have to dispose()override the function. Then we have to cookieForm()implement the function .

class  _CookieMaintenanceState  extends  State < CookieMaintenancePage > {
  ...

  final myController =  TextEditingController ();

  @override 
  void  dispose () {
    myController. dispose ();
    great . dispose ();
  }

  ...

  Widget  cookieForm () {
     return  Column (
      children :  < Widget > [
         TextField (controller : myController),
         ElevatedButton (
          child :  text ( 'append' ),
          onPressed : () {
             if (myController.text.isNotEmpty) {
               setState (() {
                _cookies. addCookie (myController.text);
                myController.text =  '' ;
              });
            }
          }
        )
      ]
    );
  }
}

The setState () function

Ok, the code can be read somehow, but what’s this setState()thing about?

Whenever we change the state of our application, the dependent widgets have to be redrawn.

Specifically, this means that the list of cookies has to be redrawn when we add new wisdom. But how is Flutter supposed to know that the condition has changed?

The function is used for this setState(). You get a (callback) function as a parameter. It does this at the appropriate time and then causes the page to be redesigned.

In our case we define a function ‘on ther fly’. With () {}we create a so-called lambda function. It doesn’t want any parameters and does whatever we put inside the curly braces. We pass this lambda function to setState () as an argument.

Try it out!

Then change the call home: CookiePage(),in the MyApp class home: CookieMaintenancePage(),and try out the code.

Switch between pages

Next, let’s connect the two sides. It’s not that difficult. We simply install one IconButtonin the AppBar of CookiePage which sends us to the CookieMaintenancePage with the help of a navigator . We come back then simply with the ‘back button’.

class  CookiePage  extends  StatelessWidget {
   final cookies =  Cookies ();
  @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Cookie of the Day' ),
        actions :  actions (context), // <- new
      ),
      body :  Center (
        child :  text ( '$ { cookies.cookieOfTheDay }' ),
      )
    );
  }

  // new 
  List < Widget >  actions ( BuildContext context) {
     return [
       IconButton (
          icon :  Icon ( Icons .edit_rounded),
          onPressed : () {
             Navigator . push (context,
                 MaterialPageRoute (builder : (context) =>  CookieMaintenancePage ()));
          }
      )
    ];
  }
}

Two times cookie data?

Let’s look at what we’ve done so far. The CookiePage is a StatelessWidget with a constant cookie which is re-instanced each time it is redrawn. We have implemented the CookieMaintenancePage as a StatefulWidget, which instantiates the _cookies variable exactly once in its state and which is retained for as long as the CookieMaintenancePage exists (is displayed).

class  CookiePage  extends  StatelessWidget {
   final cookies =  Cookies (); // new instance on every redraw
  ...
}
class  _CookieMaintenanceState  extends      State < CookieMaintenancePage > {
   Cookies _cookies =  Cookies (); // One instance for the whole lifetime of the page
  ...
}

So we have two different instances of the cookie data.

That’s not right. We need an instance which is used by both sides.

Condition management in Flutter

Flutter has no idea of ​​how to solve the global state management problem. In the article State Management you will find an overview of what you could use.

Since Flutter recommends the provider pattern , I’ll show you this.

Provider is easy.

• First, we have to make our data an ‘observable’.
• Second, we create an instance of the data and install it somewhere high in the Widegt hierarchy.
• We can then access the data in any widget in this hierarchy, modify it and thereby trigger an automatic redraw.

So let’s do that 😀

So that we can use the provider package, we have to specify in the ‘pubspec.yaml’ file that we need it. Open this file, search for the entry ‘dependencies:’ and adjust the entry as follows:

dependencies :
   provider : ^ 4.3.3 ## <- new 
  flutter :
     sdk : flutter

Step 1

Our cookies class must ChangeNotifierinherit from and notifyListeners()call the function every time its internal state changes .

class  Cookies  extends  ChangeNotifier { // <- new
  ...

  addCookie ( String wisdom) {
    _cookies. add (wisdom);
    notifyListeners (); // <- new
  }
}

step 2

We create main()a cookies object in the function and pass this as a parameter to the MyAppwidget, which inserts it into the widget hierarchy. We do this by packing our MaterialApp into a provider widget:

import  'package: provider / provider.dart' ;
...

class  MyApp  extends  StatelessWidget {
   final cookies;
  MyApp ( this .cookies);

  @override 
  Widget  build ( BuildContext context) {
     return  Provider < Cookies > ( // <- new 
      create : (_) => cookies, // provide cookie data 
      child :  MaterialApp (
        ...
      )
    ); // <- new
  }
}

Step 3

In the CookiePage we delete the constant cookies and get the required data from the provider at the beginning of the build () function. The rest remains as usual.

class  CookiePage  extends  StatelessWidget {
   // <- deleted 
  @override 
  Widget  build ( BuildContext context) {
     var cookies =  Provider . of < Cookies > (context); // <- new 
    return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Cookie of the Day' ),
        actions :  actions (context),
      ),
      body :  Center (
      child :  text ( '$ { cookies.cookieOfTheDay }' ),
      )
    );
  }

  ...
}

We do the same thing in _CookieMaintenanceState.

However, the effort is a bit greater because we have outsourced the creation of the form and the ListView to two functions. In each of these functions, we need access to the cookie data. We can only find the right provider if we have the current context. We must therefore transfer this when calling the functions and also receive it there.

As for the simplicity, I’ll give you the whole code below.

class  _CookieMaintenanceState  extends  State < CookieMaintenancePage > {
   // <- deleted 
  final myController =  TextEditingController ();

  @override 
  void  dispose () {
    myController. dispose ();
    great . dispose ();
  }

  @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Manage Cookies' ),
      ),
      body :  Center (
        child :  Column (
          mainAxisAlignment :  MainAxisAlignment .center,
          children : [
             Expanded (child :  cookieList (context)), // <- changed 
            cookieForm (context) // <- changed
          ],
        ),
      ),
    );
  }

  Widget  cookieList ( BuildContext context) { // <- changed 
    var _cookies =  Provider . of < Cookies > (context); // <- new 
    return  ListView . builder (
      itemCount : _cookies.cookies.length,
      itemBuilder : (context, index) {
         return  Card (child :  ListTile (
          title :  Text (_cookies.cookies [index]),
        ));
      }
    );
  }

  Widget  cookieForm ( BuildContext context) { // <- changed 
    var _cookies =  Provider . of < Cookies > (context); // <- new 
    return  Column (
      children :  < Widget > [
         TextField (controller : myController),
         ElevatedButton (
          child :  text ( 'append' ),
          onPressed : () {
             if (myController.text.isNotEmpty) {
               setState (() {
                _cookies. addCookie (myController.text);
                myController.text =  '' ;
              });
            }
          }
        )
      ]
    );
  }
}

state of things

Not bad. With just 142 lines of code, we wrote a complete app.

It demonstrates how we switch between different pages, that there are stateless (StatelesWidget) and stateful (StatefullWidget) and how we can install ‘global’ state so that it can not only be used in all widgets, but also triggers automatic redrawing if his condition changes.

The only thing that is missing now is the possibility to order a new fortune cookie by shaking it on the CookiePage.

Hardware access with Flutter

Flutter makes it possible to create applications for the web, the desktop and for mobile devices. Both Android and the Apple operating system are supported on the mobile devices. Ideally, you write code once and the app runs everywhere.

Sensors

We generally only find sensors in mobile devices. They are addressed and evaluated by drivers of the corresponding operating system. Since Flutter is a cross-platform development environment, it must communicate with the existing operating system, which in turn communicates with the sensor hardware.

In Flutter there is the possibility to write code which calls platform-specific code. We can then write code for each operating system that omits the sensors and takes care of communication with Flutter. For this we have to write platform-specific code for each supported platform.

But that’s exactly what we don’t want. Let someone else do it for us, please😈.

So we need a suitable library.

on https://pub.dev/ we can search for suitable libraries. Let’s try the sensors package. According to the installation instructions, we add to our pubspec.yaml file.

dependencies :
   provider : ^ 4.3.3 
  sensors : ^ 0.4.2 + 6 ## <- new 
  flutter :
     sdk : flutter

The sensors package gives us access to the acceleration and gyroscope sensors.

You can find an example of how we handle sensor data under SensorPage .

CookiePage with shake

We would certainly be able to program a shake detector with the existing sensor data. Fortunately, such a library already exists and we will use it.

Install shake .

dependencies :
   provider : ^ 4.3.3 
  shake : ^ 0.1.0 ## <- new 
  flutter :
     sdk : flutter

Unfortunately, the shake sensor has to be used in a StatefulWidget. So we adapt our CookiePage accordingly and add a initState()function according to the example from shake. In onPhoneShake:we do not have to do anything except call setState (), a redraw is triggered automatically. This in turn acquires a new piece of wisdom in terms of the cookies data structure.

class  CookiePage  extends  StatefulWidget {
   @override 
  _CookiePageState  createState () =>  _CookiePageState ();
}

class  _CookiePageState  extends  State < CookiePage > {

  @override 
  void  initState () {
     great . initState ();
    ShakeDetector detector =  
      ShakeDetector . autoStart (onPhoneShake : () {
       setState (() {}); // Force redraw
    });
  }

...

}

Sh …, everything is red! Why is this thing not working?

Flutter tries to protect us from mistakes. To do this, it analyzes the code and, if necessary, issues warnings on the screen.

The most important part of the error message is:

This is likely a mistake, as Provider will not automatically update dependents when Cookies is updated.

Flutter noticed that our page will not be automatically redrawn if the cookie data changes.

But that’s exactly what we want. We do not want new wisdom when something has changed in the cookie data, but only when we ask for new wisdom by shaking it.

As a solution, Flutter suggests to suppress the analysis output in main (). And that’s exactly what we’re doing now:

void  main () {
   Provider .debugCheckInvalidValueType =  null ; // <- add this to disable check

  runApp ( MyApp ());
}

Now the thing should actually work 😀

Note, however, that such mechanisms should only be switched off if you are really sure that you know better.

SensorPage

The SensorPage only shows the bare essentials. We need a StatefulWidget so that we can attach ourselves to the initState()function in the accelerometerEvents. dispose()We then log off again in the function. In the callback function, we only accept every 20th event, copy the received values ​​into the local state and trigger the redraw.

In the build()function we create a rudimentary GUI to display the data.

Note that we directionIcon()convert the data in the function into directional information using a threshold value. Never test for a specific sensor value but always against a threshold or an interval. Sensor values ​​are tainted with noise and it is possible that a certain value never occurs.

import  'package: flutter / material.dart' ;
import  'dart: async' ;
import  'package: sensors / sensors.dart' ;

class  SensorPage  extends  StatefulWidget {
   @override 
  _SensorPageState  createState () =>  _SensorPageState ();
}

class  _SensorPageState  extends  State < SensorPage > {
   int delayCount =  0 ;
  double _ax =  0 , _ay =  0 , _az =  0 ;
  StreamSubscription < dynamic > _accelerometerSubscription;

  void  initState () {
     super . initState ();
    // Subscribe for accelerator events 
    _accelerometerSubscription = accelerometerEvents. listen ((event) {
       // We do not need evey event 
      if ( ++ delayCount <  20 ) return ; delayCount =  0 ;

      // whenever we get new data, force redraw by calling setState () 
      setState (() {
         // Copy values ​​to local state 
        _ax = event.x; _ay = event.y; _az = event.z;
      });
    });
  }

  void  dispose () {
     super . dispose ();
    _accelerometerSubscription. cancel ();
  }

  @override 
  Widget  build ( BuildContext context) {
     return  Scaffold (
      appBar :  AppBar (
        title :  Text ( 'Sensor' ),
      ),
      body :  Center (
        child :  Column (
          children : [
             Expanded (child :  Center (child :  directionIcon ( 2.5 ))),
             Text ( 'Accel: x: $ { _d2s (_ax) }, y: $ { _d2s (_ay) }, z: $ { _d2s (_az ) } ' , textScaleFactor :  1.5 ,),
          ],
        ),
    ));
  }

  Widget  directionIcon ( double threshold) {
     if (_ay <  - threshold) return  Icon ( Icons .arrow_upward);
    if (_ay >   threshold) return  Icon ( Icons .arrow_downward);
    if (_ax <  - threshold) return  Icon ( Icons .arrow_left_sharp);
    if (_ax >   threshold) return  Icon ( Icons .arrow_right_alt);
    return  Icon ( Icons .account_circle_outlined);
  }

  String  _d2s ( double d) => d. toStringAsFixed ( 2 );
}

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.

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.

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 RangeSlider, DatePicker with support for date range and time picker with the new style.

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.

You can get more free Flutter tutorials you can follow these courses:

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.

Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

Dream11

NuBank

Reflectly app

Abbey Road Studios

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
