The screen is not navigating in onLaunh()and onResume() methods of firebase messaging, And I tried to show local notification to navigate scree but still fail.

My Payload

onResume payload======{notification: {}, data: {notification_type: VideoCalling, role: ROLE_CONSILIER_CARIERA, google.original_priority: high, google.sent_time: 1576478554401, google.delivered_priority: high, appointment: {"video_duration":"0","mod_desfasurare":"3","observatii_destinatar":"","initiator":"204","observatii_initiator":"chdh","data_sfarsit_programare":"2019-12-14 12:00:00","created_by_user":"204","data_inceput_programare":"2019-12-14 11:00:00","status_destinatar":"1","status_initiator":"1","descriere":"chhxsh","destinatar":"246","tip":"0","id":"241","data_adaugarii":"2019-12-13 15:56:39","titlu":"test 13 dc","disponibilitate":"346"}, body: Apelul video programat este activ acum pentru student, title: Escouniv, click_action: FLUTTER_NOTIFICATION_CLICK, google.message_id: 0:1576478554409777%dd3b8f6edd3b8f6e, collapse_key: com.sys.escouniv, google.ttl: 2419200, from: 347273381579, id: 50, status: done}}

  onLaunch: (Map<String, dynamic> msg) async {
        Log.e('onLaunch====== ', msg);
        Log.e('onLaunch data====== ', msg['data']);
       // showNotification(msg);
        _navigateToItemDetail(msg);
      /*  Future.delayed(
            const Duration(seconds: 4),
                () =>    Navigator.push(
          context,
          new MaterialPageRoute(builder: (context) => new StudentTutorials(user:UserType.Student,)),
        ));*/

      },

@Anand Saga here I followed the same thing , As i understand why I'm getting key notification null but in onMessage i'm getting notification with title and body.

Add one bool flag and set it true after build complete like this

WidgetsBinding.instance.addPostFrameCallback((_){ flag = true; });

And use this timer inside your onLaunch

Timer.periodic(Duration(seconds: 1), (timer){
  if(flag) {
    timer.cancel();
    doNavigation();
  }
});

    Your code is reaching me inside in `Timer` but i stuck in ` Navigator operation requested with a context that does not include a Navigator` I'm trying to rid off from this situation. – Farhana Naaz Ansari Dec 16 '19 at 07:27
  • Could you please shared proper example, not able to understand where should we add this code and how they communicate with each other. Thank you in advance. – Sathish Gadde Jul 23 '20 at 09:44
