Flutter Local Notifications

Here we will cover every thing about flutter local notifications. We will cover here the below topics,

1. Showing notification

2. Notification Icon

3. Custom notification sound

First go ahead and install the plugin

then in the main.dart file put the code below

final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      debugShowCheckedModeBanner: false,
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  void initState(){
    super.initState();
    Noti.initialize(flutterLocalNotificationsPlugin);
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: const BoxDecoration(
          gradient: LinearGradient(
              begin: Alignment.topLeft,
              end: Alignment.bottomRight,
              colors: [Color(0xFF3ac3cb), Color(0xFFf85187)])),
      child: Scaffold(
          backgroundColor: Colors.transparent,
          appBar: AppBar(
            backgroundColor: Colors.blue.withOpacity(0.5),

          ),
          body: Center(
            child: Container(
              decoration: BoxDecoration(
                  color: Colors.white,
                  borderRadius: BorderRadius.circular(20)
              ),
              width: 200,
              height: 80,
              child: ElevatedButton(
                onPressed: (){

                  Noti.showBigTextNotification(title: "New message title", body: "Your long body", fln: flutterLocalNotificationsPlugin);
                }, child: Text("click"),
              ),
            ),
          )),
    );
  }
}

Then create a new class called Noti.dart and put the code below

class Noti{
  static Future initialize(FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin) async {
    var androidInitialize = new AndroidInitializationSettings('mipmap/ic_launcher');
    var iOSInitialize = new IOSInitializationSettings();
    var initializationsSettings = new InitializationSettings(android: androidInitialize,
        iOS: iOSInitialize);
    await flutterLocalNotificationsPlugin.initialize(initializationsSettings );
  }

  static Future showBigTextNotification({var id =0,required String title, required String body,
    var payload, required FlutterLocalNotificationsPlugin fln
  } ) async {
    AndroidNotificationDetails androidPlatformChannelSpecifics =
    new AndroidNotificationDetails(
      'you_can_name_it_whatever1',
      'channel_name',

      playSound: true,
      sound: RawResourceAndroidNotificationSound('notification'),
      importance: Importance.max,
      priority: Priority.high,
    );

    var not= NotificationDetails(android: androidPlatformChannelSpecifics,
        iOS: IOSNotificationDetails()
    );
    await fln.show(0, title, body,not );
  }

}
