Флаттер: PlatformException (sign_in_failed, com.google.android.gms.common.api.ApiException: 10:, null)

Question

У меня есть приложение Flutter, и я пытаюсь разрешить пользователям входить в их Gmail, потому что я хочу иметь возможность перечислять свои электронные письма.Когда я нажимаю LoginButton, мне выдается запрос на вход в Gmail, и я ввожу свои учетные данные, но затем он возвращается к экрану с LoginButton, и я сталкиваюсь с ошибкой:

Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Что я пробовал:

• Добавлено google-services.json в / android / app и добавлено GoogleService-Info.plist в ios / Runner.
• Включение Gmailдля аутентификации Firebase.
• Добавление моих отладочных SHA1 и SHA256 к моей аутентификации Firebase.
• Заполнение формы согласия OAuth (я сделал это после всего остального. Я не знаю, повлияет ли это наэто.)

Есть идеи?Спасибо!

Вот мой код:

class AuthService {
  final GoogleSignIn _googleSignIn = GoogleSignIn();
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _db = Firestore.instance;

  Observable<FirebaseUser> user;
  Observable<Map<String, dynamic>> profile;
  PublishSubject loading = PublishSubject();

  AuthService() {
    user = Observable(_auth.onAuthStateChanged);

    profile = user.switchMap((FirebaseUser u) {
      if (u != null) {
        return _db
            .collection('users')
            .document(u.uid)
            .snapshots()
            .map((snap) => snap.data);
      } else {
        return Observable.just({});
      }
    });
  }

  Future<FirebaseUser> googleSignIn() async {
    loading.add(true);
    GoogleSignInAccount googleUser = await _googleSignIn.signIn();
    GoogleSignInAuthentication googleAuth = await googleUser.authentication;
    final AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
    FirebaseUser user = (await _auth.signInWithCredential(credential)).user;

    updateUserData(user);
    print("signed in " + user.displayName);

    loading.add(false);
    return user;
  }

  void updateUserData(FirebaseUser user) async {
    DocumentReference ref = _db.collection('user').document('user.uid');

    return ref.setData({
      'uid': user.uid,
      'email': user.email,
      'photoURL': user.photoUrl,
      'displayName': user.displayName,
      'lastSeen': DateTime.now()
    }, merge: true);
  }

  void signOut() {
    _auth.signOut();
  }
}

final AuthService authService = AuthService();
