I have a dashboard screen where in the initState I am initializing the Firebase notification and local notification. When the app is foregrounded it’s getting the local notification and getting the notification correctly. But when the app is backgrounded then it’s getting two notifications one from the firebaseMessaging and another from the local notification which is kind of duplicate and false. I want to get rid of it and want only the Firebase messaging to work when the app is backgrounded.

Community suggests this might be my solve:
Notification show twice on flutter. But the available solution on that are not for me. If i dont use the navigation from the payload that solves might work but if i dont use message.notification the how can I navigate from notifications? So as per my understanding both are different questions. And more over the notification from the local notification, the payload is coming as empty. But in the second notification the payload is coming with data.

My code snippets:

initState

@override
 void initState() {
    super.initState();

    currentTab = widget.tab;
    initFirebaseMessaging();
    _selectTab(currentTab);
  }

Firebase messaging

 initFirebaseMessaging() async {
    await firebaseMessaging.requestPermission(
      alert: true,
      announcement: false,
      badge: true,
      carPlay: false,
      criticalAlert: false,
      provisional: false,
      sound: true,
    );
    final fcm = await firebaseMessaging.getToken();
    logger.w("Driver Token: $fcm");
    initPushNotification();
    initLocalNotifications();
  }

Push notifications

Future initPushNotification() async {
    ///if app is opened from terminated state : onTap actions performed
    firebaseMessaging.getInitialMessage().then(
      (RemoteMessage? message) {
        if (initialRemoteMessage != null) {
          RemoteNotification? notification = initialRemoteMessage!.notification;
          logger.w(
              "Driver title:${notification?.title} Driver data: ${notification?.body}");
          logger.w("Driver Data:${message?.data}");
          moveScreenFromNotification(initialRemoteMessage!.data);
          flutterToast(initialRemoteMessage!.messageType ?? '');
        } else if (message != null) {
          RemoteNotification? notification = message.notification;
          logger.w("RemoteNotification");
          logger.w("title:${notification?.title} data: ${notification?.body}");
          logger.w("Data:${message.data}");
          moveScreenFromNotification(message.data);
          flutterToast(message.messageType ?? '');
          initialRemoteMessage = message;
        }
      },
    );

    //*If app is in background state : actions performed
    FirebaseMessaging.onMessageOpenedApp.listen((message) {
      moveScreenFromNotification(message.data);
    });
    //*If app is in background state
    FirebaseMessaging.onBackgroundMessage(handleBackGroundMessage);

    //* If the app is in foreground state:(Local notifications)
    FirebaseMessaging.onMessage.listen((message) {
      final notification = message.notification;
      if (notification == null) return;
      moveScreenFromNotification(message.data);
      localNotification.show(
          notification.hashCode,
          notification.title,
          notification.body,
          NotificationDetails(
              android: AndroidNotificationDetails(
                  androidChannel.id, androidChannel.name)),
          payload: jsonEncode(message.toMap()));
    });
  }

Local notifications

    Future initLocalNotifications() async {
    const ios = IOSInitializationSettings();
    const android = AndroidInitializationSettings("@drawable/logo");
    const setting = InitializationSettings(android: android, iOS: ios);
    await localNotification.initialize(setting,
        onSelectNotification: (payload) {
      if (payload?.contains(".pdf") ?? false) {
        logger.w("PDF Executing");
        OpenFile.open(payload);
      } else {
        logger.w("Driver Message is Executing");
        logger.w("Payload: $payload");
        final message = RemoteMessage.fromMap(jsonDecode(payload ?? ""));
        logger.w("DATA from local: ${message.data}");
        handleBackGroundMessage(message);
        moveScreenFromNotification(message.data);
      }
    });
    final platform = localNotification.resolvePlatformSpecificImplementation<
        AndroidFlutterLocalNotificationsPlugin>();
    await platform?.createNotificationChannel(androidChannel);
  }

handle background message

  Future<void> handleBackGroundMessage(RemoteMessage message) async {
  RemoteNotification? notification = message.notification;
  NotificationService notificationService = NotificationService(channelId: "D");
  await notificationService.showNotification(message: message);
  flutterToast(notification?.body ?? '');
  }

These are all the associated snippets. Is there any way to get one notification while the app is in the background and not use the local notification function?

I have tried logging to understand what is going on. But it seems like the way of implementation is causing this. I cannot think of anything better for now as I am kind of new to the local notifications.
