Initialize

 await FCMConfig.init();
 //or if you need to listen background notification
 //Pass top level function

  Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage  message) async {
   print("Handling a background message: ${message.messageId}");
  }
  
  void main() async {
    FCMConfig.init(onBackgroundMessage: _firebaseMessagingBackgroundHandler);
    runApp(MaterialApp(
      home: MyHomePage(),
    ));
  }

• To know more about background handler please https://firebase.flutter.dev/docs/messaging/usage#background-messages

Get token

FCMConfig.getToken().then((token) {
      print(token);
 });

To get notification that launched the application

 await FCMConfig.getInitialMessage();// may be null
 

Now to listen to incomming notification :

• First option

  class MyScreen extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      return FCMNotificationListener(
        onNotification:
            (RemoteMessage notification, void Function() setState) {},
        child: SizedBox(),
      );
    }
  }
  

• Second option

  class MyScreen extends StatefulWidget {
    @override
    _MyScreenState createState() => _MyScreenState();
  }
    
  class _MyScreenState extends State<MyScreen>
      with FCMNotificationMixin {
    @override
    Widget build(BuildContext context) {
      return SizedBox();
    }
    
    @override
    void onNotify(RemoteMessage notification) {
      // do some thing
    }
  }
    
  

To listen notification tap there is FCMNotificationClickListener and FCMNotificationClickMixin but be aware that its recommended to use it in main screen
