Place Picker on Google Maps for Flutter

Google Maps Place Picker .A Flutter plugin which provides ‘Picking Place’ using Google Maps widget.

The project relies on below packages.

Map using Flutter’s official google_maps_flutter
Fetching current location using Baseflow’s geolocator
Place and Geocoding API using hadrienlejard’s google_maps_webservice
Builder using kevmoo’s tuple

Support

If the package was useful or saved your time, please do not hesitate to buy me a cup of coffee! ;)
The more caffeine I get, the more useful projects I can make in the future.

Getting Started

Get an API key at https://cloud.google.com/maps-platform/.

Android

Specify your API key in the application manifest android/app/src/main/AndroidManifest.xml:

<manifest ...
  <application ...
    <meta-data android:name="com.google.android.geo.API_KEY"
               android:value="YOUR KEY HERE"/>

NOTE: As of version 3.0.0 the geolocator plugin switched to the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project is also upgraded to support AndroidX. Detailed instructions can be found here.

The TL;DR version is:

1. Add the following to your “gradle.properties” file:

android.useAndroidX=true
android.enableJetifier=true

2. Make sure you set the compileSdkVersion in your “android/app/build.gradle” file to 28:

android {
 compileSdkVersion 28

 ...
}

3. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

iOS

Specify your API key in the application delegate ios/Runner/AppDelegate.m:

#include "AppDelegate.h"
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GMSServices provideAPIKey:@"YOUR KEY HERE"];
  [GeneratedPluginRegistrant registerWithRegistry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

Or in your swift code, specify your API key in the application delegate ios/Runner/AppDelegate.swift:

import UIKit
import Flutter
import GoogleMaps

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GMSServices.provideAPIKey("YOUR KEY HERE")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Opt-in to the embedded views preview by adding a boolean property to the app’s Info.plist file
with the key io.flutter.embedded_views_preview and the value YES.

Usage

Basic usage

You can use PlacePicker by pushing to a new page using Navigator.
When the user picks a place on the map, it will return the result (PickResult).

Navigator.push(
      context,
      MaterialPageRoute(
        builder: (context) => PlacePicker(
          apiKey: APIKeys.apiKey,   // Put YOUR OWN KEY here.
          onPlacePicked: (result) { 
            print(result.address); 
            Navigator.of(context).pop();
          },
          initialPosition: HomePage.kInitialPosition,
          useCurrentLocation: true,
        ),
      ),
    );

PickResult

Parameter	Type	Description
placeId	String	A textual identifier that uniquely identifies a place. To retrieve information about the place, pass this identifier in the placeId field of a Places API request. See PlaceId for more information.
geometry	Geometry	Contains geometry information about the result, generally including the location (geocode) of the place and (optionally) the viewport identifying its general area of coverage.
address	String	A string containing the human-readable address of this place. Often this address is equivalent to the “postal address”.
types	List <String\>	Contains an array of feature types describing the given result. See the list of supported types. XML responses include multiple <type> elements if more than one type is assigned to the result.
addressComponents	List <AddressComponent\>	An array containing the separate components applicable to this address.

More info about results at google.

PlacePicker

Parameter	Type	Description
apiKey	String	(Required) Your google map API Key
onPlacePicked	Callback(PickResult)	Invoked when user picks the place and selects to use it. This will not be called if you manually build ‘selectedPlaceWidgetBuilder’ as you will override default ‘Select here’ button.
initialPosition	LatLng	Initial center position of google map when it is created. If useCurrentLocation is set to true, it will try to get device’s current location first using GeoLocator.
useCurrentLocation	bool	Whether to use device’s current location for initial center position
desiredLocationAccuracy	LocationAccuracy	Accuracy of fetching current location. Default to ‘high’.
hintText	String	Hint text of search bar
searchingText	String	A text which appears when searching is performing. Default to ‘Searching…’
searchBarHeight	double	Height of search bar. Default 40. Recommended using together with contentPadding.
contentPadding	EdgeInsetsGeomery	content padding of search bar input textField’s InputDecoration
proxyBaseUrl	String	Used for API calling on google maps. In case of using a proxy the baseUrl can be set. The apiKey is not required in case the proxy sets it.
httpClient	Client	Used for API calling on google maps. In case of using a proxy url that requires authentication or custom configuration.
autoCompleteDebounceInMilliseconds	int	Debounce timer for auto complete input. Default 500
cameraMoveDebounceInMilliseconds	int	Debounce timer for searching place with camera(map) dragging. Default 750
intialMapType	MapType	MapTypes of google map. Default normal.
enableMapTypeButton	bool	Whether to display MapType change button on the map
enableMyLocationButton	bool	Whether to display my location button on the map
onAutoCompleteFailed	Callback(String)	Invoked when auto complete search is failed
onGeocodingSearchFailed	Callback(String)	Invoked when searching place by dragging the map failed
onMapCreated	MapCreatedCallback	Returens google map controller when created
selectedPlaceWidgetBuilder	WidgetBuilder	Specified on below section
pinBuilder	WidgetBuilder	Specified on below section

Customizing picked place visualisation

By default, when a user picks a place by using auto complete search or dragging the map, we display the information at the bottom of the screen (FloatingCard).

However, if you don’t like this UI/UX, simple override the builder using ‘selectedPlaceWidgetBuilder’. FlocatingCard widget can be reused which floating around the screen or build entirly new widget as you want. It is stacked with the map, so you might want to use Positioned widget.

Note that using this customization WILL NOT INVOKE [onPlacePicked] callback as it will override default ‘Select here’ button on floating card

...
PlacePicker(apiKey: APIKeys.apiKey,
            ...
            selectedPlaceWidgetBuilder: (_, selectedPlace, state, isSearchBarFocused) {
              return isSearchBarFocused
                  ? Container()
                  // Use FloatingCard or just create your own Widget.
                  : FloatingCard(
                      bottomPosition: MediaQuery.of(context).size.height * 0.05,
                      leftPosition: MediaQuery.of(context).size.width * 0.05,
                      width: MediaQuery.of(context).size.width * 0.9,
                      borderRadius: BorderRadius.circular(12.0),
                      child: state == SearchingState.Searching ? 
                                      Center(child: CircularProgressIndicator()) : 
                                      RaisedButton(onPressed: () { print("do something with [selectedPlace] data"); },),
                   );
            },
            ...
          ),
...

Parameters	Type	Description
context	BuildContext	Flutter’s build context value
selectedPlace	PickResult	Result data of user selected place
state	SearchingState	State of searching action. (Idle, Searching)
isSearchBarFocused	bool	Whether the search bar is currently focused so the keyboard is shown

Customizing Pin

By default, Pin icon is provided with very simple picking animation when moving around.
However, you can also create your own pin widget using ‘pinBuilder’

PlacePicker(apiKey: APIKeys.apiKey,
            ...
            pinBuilder: (context, state) {
                  if (state == PinState.Idle) {
                    return Icon(Icons.favorite_border);
                  } else {
                    return AnimatedIcon(.....);
                  }
                },
            ...                        
          ),
...

Parameters	Type	Description
context	BuildContext	Flutter’s build context value
state	PinState	State of pin. (Preparing; When map loading, Idle, Dragging)

Changing Colours of default FloatingCard (Prediction tile)

While you can build your own prediction tile, you still can change the style of default tile using themeData as below:

theme: ThemeData.dark().copyWith(
        cardColor: Colors.grey,                  // Background color of the FloatingCard
        buttonTheme: ButtonThemeData(
          buttonColor: Colors.yellow,            // Select here's button color
          textTheme: ButtonTextTheme.primary,    // Applying this will automatically change text color based on buttonColor. (Button color is dark ? white / is light ? black)
        ),
        textTheme: TextTheme(
          body1: TextStyle(color: Colors.white), // This will change the text color of FloatingCard
        ),
      ),

What is GEEK

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.

Seat Reservation With Jquery And Php

Seat Reservation with jQuery

In my Online Bus Reservation System project, I got queries from many people about how to implement seat selection screen effectively. So, I decided to write on it. This post explains how to implement seat booking with jQuery. It can be used in online Bus, flight, hotel, exam support, cinema and ticket booking system.

 

HTML:

<h2> Choose seats by clicking the corresponding seat in the layout below:</h2>

    <div id="holder">

        <ul  id="place">

        </ul>   

    </div>

    <div style="float:left;">

    <ul id="seatDescription">

        <li style="background:url('images/available_seat_img.gif') no-repeat scroll 0 0 transparent;">Available Seat</li>

        <li style="background:url('images/booked_seat_img.gif') no-repeat scroll 0 0 transparent;">Booked Seat</li>

        <li style="background:url('images/selected_seat_img.gif') no-repeat scroll 0 0 transparent;">Selected Seat</li>

    </ul>

    </div>

        <div style="clear:both;width:100%">

        <input type="button" id="btnShowNew" value="Show Selected Seats" />

        <input type="button" id="btnShow" value="Show All" />          

        </div>

We will add seats in “#place” element using javascript.

Settings:

To make it generalize, settings object is used.

var settings = {

               rows: 5,

               cols: 15,

               rowCssPrefix: 'row-',

               colCssPrefix: 'col-',

               seatWidth: 35,

               seatHeight: 35,

               seatCss: 'seat',

               selectedSeatCss: 'selectedSeat',

               selectingSeatCss: 'selectingSeat'

           };

rows: total number of rows of seats.
cols: total number of seats in each row.
rowCssPrefix: will be used to customize row layout using (rowCssPrefix + row number) css class.
colCssPrefix: will be used to customize column using (colCssPrefix + column number) css class.
seatWidth: width of seat.
seatHeight: height of seat.
seatCss: css class of seat.
selectedSeatCss: css class of already booked seats.
selectingSeatCss: css class of selected seats.

Seat Layout:

We will create basic layout of seats.

var init = function (reservedSeat) {

                var str = [], seatNo, className;

                for (i = 0; i < settings.rows; i++) {

                    for (j = 0; j < settings.cols; j++) {

                        seatNo = (i + j * settings.rows + 1);

                        className = settings.seatCss + ' ' + settings.rowCssPrefix + i.toString() + ' ' + settings.colCssPrefix + j.toString();

                        if ($.isArray(reservedSeat) && $.inArray(seatNo, reservedSeat) != -1) {

                            className += ' ' + settings.selectedSeatCss;

                        }

                        str.push('<li class="' + className + '"' +

                                  'style="top:' + (i * settings.seatHeight).toString() + 'px;left:' + (j * settings.seatWidth).toString() + 'px">' +

                                  '<a title="' + seatNo + '">' + seatNo + '</a>' +

                                  '</li>');

                    }

                }

                $('#place').html(str.join(''));

            };

            //case I: Show from starting

            //init();

            //Case II: If already booked

            var bookedSeats = [5, 10, 25];

            init(bookedSeats);

 

init method is used to draw seats layout. Already booked seats array will be passed as argument of this method.

Seat Selection:

?

$('.' + settings.seatCss).click(function () {

if ($(this).hasClass(settings.selectedSeatCss)){

    alert('This seat is already reserved');

}

else{

    $(this).toggleClass(settings.selectingSeatCss);

    }

});

$('#btnShow').click(function () {

    var str = [];

    $.each($('#place li.' + settings.selectedSeatCss + ' a, #place li.'+ settings.selectingSeatCss + ' a'), function (index, value) {

        str.push($(this).attr('title'));

    });

    alert(str.join(','));

})

$('#btnShowNew').click(function () {

    var str = [], item;

    $.each($('#place li.' + settings.selectingSeatCss + ' a'), function (index, value) {

        item = $(this).attr('title');                  

        str.push(item);                  

    });

    alert(str.join(','));

})

When user clicks on available seat, it is selected and second click on same seat will unselect seat. Button “Show All” will show all booked seat numbers and “Show Selected Seats” will show selected seats only.

CSS:

?

#holder{   

height:200px;   

width:550px;

background-color:#F5F5F5;

border:1px solid #A4A4A4;

margin-left:10px;  

}

#place {

position:relative;

margin:7px;

}

#place a{

font-size:0.6em;

}

#place li

{

 list-style: none outside none;

 position: absolute;  

}   

#place li:hover

{

background-color:yellow;     

}

#place .seat{

background:url("images/available_seat_img.gif") no-repeat scroll 0 0 transparent;

height:33px;

width:33px;

display:block;  

}

#place .selectedSeat

{

background-image:url("images/booked_seat_img.gif");         

}

#place .selectingSeat

{

background-image:url("images/selected_seat_img.gif");       

}

#place .row-3, #place .row-4{

margin-top:10px;

}

#seatDescription li{

verticle-align:middle;   

list-style: none outside none;

padding-left:35px;

height:35px;

float:left;

}

In my next post, you will get how to use this in asp.net project with sql server database .

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.
