onSelectNotification Navigator not working if app closed flutter

Question

onSelectNotification when good when app open

  Future<void> onSelectNotification(String payload) async {
    Category category = Category();
    category.id = notification.idNew;
    category.email = notification.mainphoto;
    category.since = notification.since;
    category.name = notification.title;
    await Navigator.push(
        context,
        MaterialPageRoute(
            builder: (context) => FourthRoute(
                  category: category,
                )));
  }

when open and click at notification it's go to FourthRoute

but when closed it's just open app Navigator not working

problem at ios and android

i was think to use SharedPreferences inside onSelectNotification to save key and check it later

but i read dart not working when app closed

the Navigator has to be wrapped as child in MaterialApp widget, otherwise, you have to use navKey to refer you materialApp.

1. final navKey = new GlobalKey<NavigatorState>();

2. MaterialAPP(title: 'title', ..., navigatorKey: navKey)

3. And then use the key to route to your widget, 
navKey.currentState.push(MaterialPageRoute(builder: (context) => NewRoute()));

var details = await NotificationService()
    .flutterLocalNotificationsPlugin
    .getNotificationAppLaunchDetails();
if (details.didNotificationLaunchApp) {
    print(details.payload);
}

Use this code in the app entry it can get notification tapped payload

i contact support of plugin

Here

Future<void> main() async {
  // needed if you intend to initialize in the `main` function
  WidgetsFlutterBinding.ensureInitialized();

  notificationAppLaunchDetails =
      await flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails();

  var initializationSettingsAndroid = AndroidInitializationSettings('app_icon');
  // Note: permissions aren't requested here just to demonstrate that can be done later using the `requestPermissions()` method
  // of the `IOSFlutterLocalNotificationsPlugin` class
  var initializationSettingsIOS = IOSInitializationSettings(
      requestAlertPermission: false,
      requestBadgePermission: false,
      requestSoundPermission: false,
      onDidReceiveLocalNotification:
          (int id, String title, String body, String payload) async {
        didReceiveLocalNotificationSubject.add(ReceivedNotification(
            id: id, title: title, body: body, payload: payload));
      });
  var initializationSettings = InitializationSettings(
      initializationSettingsAndroid, initializationSettingsIOS);
  await flutterLocalNotificationsPlugin.initialize(initializationSettings,
      onSelectNotification: (String payload) async {
    if (payload != null) {
      debugPrint('notification payload: ' + payload);
    }
    selectNotificationSubject.add(payload);
  });
  runApp(
    MaterialApp(
      home: HomePage(),
    ),
  );
}

this is confused, onSelectNotification vs selectNotificationSubject? can you give more specific details? — Ping Woo, Aug 15 '20 at 07:15
