Flutterfire: [firebase_message] onTokenRefresh being called every time the app loads

[thanhbinh84]

Describe the bug
onTokenRefresh being called every time the app loads even the tokens are the same

To Reproduce
_firebaseMessaging.onTokenRefresh.listen((token) => _saveToken(token)); // save token when it was refreshed

Expected behavior
only fire when token is refreshed

Additional context
firebase_messaging: ^6.0.3

Still not fixed.

Still not fixed.

You can workaround by storing token local and compare to ignore in case it is the same

Yeah, this is exactly what did it :) thanks!

However this is not the expected behavior we need the library fix.

Is there any upcoming fix? This is quite disappointing.

[LukaGiorgadze]

@xJon You can do workaround, something like this:

Stream<String> fcmStream = instance.onTokenRefresh.distinct();

fcmStream.listen((token) async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  String fcmToken = prefs.getString('fcm_token');

  if (fcmToken == token) return;

  // ...
  // create new token below and save it in SharedPreferences
  // ...
});
