GoogleAuthProvider class

This class should be used to either create a new Google credential with an access code, or use the provider to trigger user authentication flows.

For example, on web based platforms pass the provider to a Firebase method (such as signInWithPopup):

GoogleAuthProvider googleProvider = GoogleAuthProvider();
googleProvider.addScope('https://www.googleapis.com/auth/contacts.readonly');
googleProvider.setCustomParameters({
  'login_hint': 'user@example.com'
});

FirebaseAuth.instance.signInWithPopup(googleProvider)
  .then(...);

If authenticating with Google via a 3rd party, use the returned accessToken to sign-in or link the user with the created credential, for example:

String accessToken = '...'; // From 3rd party provider
GoogleAuthCredential googleAuthCredential = GoogleAuthProvider.credential(accessToken: accessToken);

FirebaseAuth.instance.signInWithCredential(googleAuthCredential)
  .then(...);
