hello am trying to navigate to a second screen after clicking on notification using flutter_local_notifications https://pub.dev/packages/flutter_local_notifications

final BehaviorSubject<String?> selectNotificationSubject =
      BehaviorSubject<String?>();
  final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
      FlutterLocalNotificationsPlugin();
  void initializeNotifcations() async {
    var initialzationSettings =
        InitializationSettings(android: initializationSettingsAndroid);

    await flutterLocalNotificationsPlugin.initialize(initialzationSettings,
        onDidReceiveBackgroundNotificationResponse:
            (NotificationResponse notificationResponse) {
      selectNotificationSubject.add(notificationResponse.payload);
    });

    flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()!
        .requestPermission();
  }

  void configureDidReceiveLocalNotificationSubject() {
    print('test01');
    selectNotificationSubject.stream.listen((String? payload) async {
      print('test02');
    });
  }

not listining to the stream if you got an example of how to make it with the best practice it will help
