🐛 [firebase_messaging] onRefreshToken doesn't invoke when the app opens for the first time.

[iLoveDocs]

Bug report

When the app is opened for the first time, the onRefreshToken callback doesn't get called.

Steps to reproduce

Uninstall the app (if it is already installed) and run the following code.
The print statement doesn't print the token.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  FirebaseMessaging.instance.onTokenRefresh.listen((token) {
    print('token = $token'); // Doesn't print
  });

  runApp(...);
}

Expected behavior

The onRefreshToken should fire when the app opens (launches) for the first time.

Version:

firebase_messaging: ^14.0.3

Additional context:

I have this code in a java file and this does print the new token:

public class MessagingService extends FirebaseMessagingService {
    @Override
    public void onNewToken(@NonNull String s) {
        super.onNewToken(s);
        Log.i("Tag", "New FCM token = " + s);
    }
}

@iLoveDocs
On what platform are you seeing this behavior ?
Can you also provide flutter doctor -v and verify the same using latest plugin version ?

Android.

Yes, the latest plugin version 14.1.3 also has this same issue. Wouldn't it be better if you run the min reproducible code (and I hope this is why we need to provide it) on your end and confirm whether or not you also see this issue. This will make things go faster.

Also seeing this on firebase_messaging: ^14.5.0 platform web. I have to use getToken on each run and update the token in my db as it is different than the previous.
