Flutterfire: [FIREBASE_MESSAGING] Permission dialog does not show

[diegothucao]

I am facing an issue like the permission dialog does not show.
Below is libs:

  firebase: ^7.2.0
  firebase_core: ^0.4.3+2
  firebase_analytics: ^5.0.10
  firebase_messaging: ^6.0.9
  firebase_auth: ^0.15.4
  google_sign_in: ^4.1.1

And here is code

  final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();

  @override
  void initState() {
    super.initState();
    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("onMessage: $message");
      },
      onLaunch: (Map<String, dynamic> message) async {
        print("onLaunch: $message");
      },
      onResume: (Map<String, dynamic> message) async {
        print("onResume: $message");
      },
    );

    _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: true));

    _firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
      print("Settings registered: $settings");
    });

    _firebaseMessaging.getToken().then((String token) {
      print("token: $token");
    });
  }

The code run well but permission does not show.
I saw in log and see

flutter: token: erwY-nUtvjs:APA91bFE69nLycjJBFjW1ANEpQSYPTaZbGBWEwtdSE1hGMLw6NOsnbCqla7kDyIoFJawVSKH4cWI7SJXFROD7VdRL9HPnukPp4xiJdNgkmudoRIcIiiiBQ-MrMhTRH4BKPyhcYaI-Z9D
flutter: Settings registered: PushNotificationSettings {sound: false, alert: false, badge: false, provisional: true}

[diegothucao]

yep, i solved it
It could be

   _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: false));

not

   _firebaseMessaging.requestNotificationPermissions(
        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: true));

Then it works

Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so it's always better to open new issues and reference related issues.

        const IosNotificationSettings(
            sound: true, badge: true, alert: true, provisional: true));

Then it works

why setting provisional: false works?
what provisional: false means?

@sultanmyrza ,

UNAuthorizationOption is provisional authorization. If you don’t mind your notifications being delivered quietly, you can set true in provisional to your authorization options. This means that you don’t have to prompt the user to allow notifications — the notifications will still show up in the Notification Center.
