Я знаю, что есть еще несколько сообщений с той же ошибкой, но ни одно из решений еще не сработало для меня. Эта проблема возникает только на устройствах, которые еще не выполнили успешный вход в систему с помощью Firebase ранее. Например, если я очищу кэш и удалю его на своем личном устройстве (pixel 5), я смогу переустановить его из Android Studio, и все это будет работать нормально. Но попытка позвонить по телефону друзей в первый раз завершается неудачей со следующим:

Полный вывод ошибок:

This is what is being called where the stack trace points to:

 _firebaseMessaging = FirebaseMessaging.instance;

settings = await _firebaseMessaging.requestPermission(
  alert: true,
  announcement: true,
  badge: true,
  sound: true,
);
token = await _firebaseMessaging.getToken(); // <-- error here
 

I think this is the first place where a firebase service is doing anything on app load, so I’m not sure if it is specific to Firebase Messaging. But I honestly have no idea.

I’ve followed the FlutterFire instructions, app verification setup, as well as putting the google-services.json in android/google-services.json and android/app/google-services.json .

I’ve also tried providing FirebaseOptions , which didn’t seem to change anything.

I really have no idea what to do at this point. This is pretty much the only thing left before I can release the app and none of the solutions I’ve seen have worked. Thank you for any help in advance.
