Firebase (FCM) registration token in Flutter

Question

I am trying to send notification from Java Rest Api (using Firebase Admin sdk) to my Flutter application and it seems it requires device token to send notification and I cannot find how to get that token. I am new to Flutter and android and may be missing any of the crucial step. Please help me if you can. Thanks.

Add this to your package's pubspec.yaml file:

dependencies:   firebase_messaging: ^6.0.16 

You can install packages from the command line:

with Flutter:

$ flutter packages get 

Now in your Dart code, you can use:

import 'package:firebase_messaging/firebase_messaging.dart'; 

Implementation:

FirebaseMessaging _firebaseMessaging = FirebaseMessaging();    @override void initState() {   super.initState();   firebaseCloudMessaging_Listeners(); }  void firebaseCloudMessaging_Listeners() {   if (Platform.isIOS) iOS_Permission();    _firebaseMessaging.getToken().then((token){     print(token);   });    _firebaseMessaging.configure(     onMessage: (Map<String, dynamic> message) async {       print('on message $message');     },     onResume: (Map<String, dynamic> message) async {       print('on resume $message');     },     onLaunch: (Map<String, dynamic> message) async {       print('on launch $message');     },   ); }  void iOS_Permission() {   _firebaseMessaging.requestNotificationPermissions(       IosNotificationSettings(sound: true, badge: true, alert: true)   );   _firebaseMessaging.onIosSettingsRegistered       .listen((IosNotificationSettings settings)   {     print("Settings registered: $settings");   }); }

With firebase_messaging: ^10.0.0, you can directly get the token using

String? token = await FirebaseMessaging.instance.getToken(); 

or

FirebaseMessaging.instance.getToken().then((value) {   String? token = value; });
