I tried passing our OAuth 2.0 Client ID (which is set here) without success like this:įinal _googleSignIn = GoogleSignIn( scopes:, clientId: 'MY-CLIENT-ID' ) As soon as I add the generated google-services.json from Firebase to my project, the sign in fails with the exception mentioned below. We were using the google_sign_in package without Firebase for a few months now without any problems, while managing users in a different database.įor a new feature I had to implement Firebase.
