I managed to solve it. In my case, I was using the Android client ID in my code instead of the Web client ID. Additionally, if you're making a release build and have added your SHA1 from the Google Play Console on Firebase, it seems that Google Sign-In will only work when installed directly from the store. To test, you can use internal testing: https://play.google.com/intl/en/console/about/internal-testing/

SOLVED!
If you have problems with DeveloperError Exception of type 'Google.GoogleSignIn+SignInException' was thrown.

• Go to Google cloud console -> APIs & Services -> Create Credentials
• Then you need to create a new OAuth Client ID with web application type, use its Client ID instead of your android client ID.
  (This Web client ID you create is use to get ID token of a user from google. And remember the client ID auto generated by Firebase won’t work, you need to create it manually)

(*) Also if it's not work, you may need to add API Key by go to APIs & Services -> Create Credentials -> API Key, config OAuth consent screen and add service accounts if you don't have.
One more thing you need to know, this google Id Token is isolated from firebase, you can get it by just using google cloud without config your firebase. Firebase will require this Id Token for Firebase.Auth.

The same error, to be honest, this SDK is very difficult to use.
