I'm trying to make google sign in feature in my app but this error keeps showing up

I've done the following:

  • added support email
  • activated google signin in flutter console
  • generated the sha1 and signed it to firebase
  • added the following dependencies:
    • firebase_core: ^0.4.0+6
    • firebase_auth: ^0.11.1+8
    • google_sign_in: ^4.0.4
    • rxdart: ^0.22.0
    • cloud_firestore: ^0.12.7
  • updated gradle to version 5.1.1 (latest for the time being posted)

what I already tried:

here is the brains of the app

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:google_sign_in/google_sign_in.dart';
import 'package:rxdart/rxdart.dart';

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,
    );

    final FirebaseUser user = await _auth.signInWithCredential(credential);
    print("signed in " + user.displayName);

    updateUserData(user);

    loading.add(false);
    print("signed in " + user.displayName);
    return user;
  }

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

I found the answer here https://github.com/flutter/flutter/issues/33393#issuecomment-510395178 you don't have to add the links listed in the comment, just update the picture with anything and it will work

the docs needs to be updated

For me adding scopes and hostedDomain in GoogleSignIn method works.

final GoogleSignInAccount? googleUser = await GoogleSignIn(
        scopes: ['email', 'profile'],
        hostedDomain: '',
      ).signIn();
