I have a Flutter app and I am trying to allow users to sign into their Gmail because I want to be able to list out their emails. When I press my LoginButton, I get prompted with a Gmail login, and I enter in my credentials, but then it goes back to the screen with the LoginButton and I am faced with the error:

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

What I have tried:

  • Added google-services.json to /android/app and added GoogleService-Info.plist to ios/Runner.
  • Enabling gmail for Firebase authentication.
  • Adding my debug SHA1 and SHA256 to my firebase authentication.
  • Filling out the OAuth consent form (I did this after everything else. I don't know if that would affect it.)

Any ideas? Thanks!

Here is my code:

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();

  • Can you also specify in your question if you have downloaded `google-services.json` and added to your android project at ./android/app/google-services.json? – Chenna Reddy Sep 21 '19 at 20:28
  • Yes, I have added `google-services.json` to /android/app and added `GoogleService-Info.plist` to ios/Runner. – Riley Fitzpatrick Sep 21 '19 at 20:36
  • I'm having this issue as well. We've been using Google sign in smoothly for the past year, so I know the config is fine. It's failing within GoogleSignIn.signIn(). I can see the account in firebase under the Authentication section as well. – ThinkDigital Sep 27 '19 at 20:29
  • I am facing the same issue. I have been using google signin for more than a year too. Did you find a solution? Please help – Sunoj Vijayan Jan 07 '20 at 09:38

I also faced this issue..In my case, I tried to implement GoogleSignIn in one of my apps that is already at production level..

When I tried to do this..I also got the same error.. APIException: 10.. looks like yours is also the same case..

I tried many times..but, finally, I ended up compromising and decided not to include GoogleSignIn in my app..

But, again..I solved it..by adding 2 SHA1 keys to the FireBase Project..one for the debug mode and other for release mode..

If I put only debug SHA1 key..it is not working in release mode but working fine in debug mode and if I put only release SHA1 key..it is not working in debug mode but working fine in release mode .

Not sure why is it happening..but it is happening..and somehow it is working fine..

Ok..now..what is debug and release key.. aren't they the same..how do I get them..?

Here it is..

Go to your project in Command Prompt.. then cd android and then type..

gradlew signingReport

It will give the SHA1 keys..

There is one key generated by the debug keystore and the other by the release keystore..

Add both of them to the project..and it works(hopefully)..as it did for me..

Hope it helps..

Note: I'm using Windows..not sure if it is the same process to generate keys on Mac as well..

just connect the SHA and problem solved https://developers.google.com/android/guides/client-auth

and replace analytic dependencies for:

implementation 'com.google.firebase:firebase-core:16.0.6'

    So that this answer isn’t dependent on the availability of the link, would you mind editing your answer to summarize how to connect the SHA? – Jeremy Caney May 18 '20 at 00:12
