@Rexios80 - Please provide a code sample for me to drop in to example app so I know specifically what you're referring to. Thanks.

@russellwheatley The example code in the readme has this issue: https://pub.dev/packages/firebase_ui_auth

Using that code, the app does not go to the signed in page after registering a new user because there is no handler for the UserCreated event

I'm running into this as well - my newState goes from SigningIn to UserCreated and then never throws the SignedIn status. I'm assuming I'm safe to stop at UserCreated but this tripped me up as well as the documentation that @Rexios80 posted is what I was following, waiting for the status to hit SignedIn.

AuthStateListener<OAuthController>(
                child: OAuthProviderButton(
                    provider: GoogleProvider(
                        clientId:
                            'OMITTED.apps.googleusercontent.com')),
                listener: (oldState, newState, ctrl) {
                  dPrint('Old state: $oldState, New state: $newState');
                  if (newState is SigningIn) {
                    dPrint('Signing in...');
                  } else if (newState is UserCreated) {
                    dPrint('User created...');
                  } else if (newState is SignedIn) {
                    dPrint('Signed in with Google');
                    if (context.mounted) {
                      dPrint('Navigating to finish profile page');
                      Navigator.pushReplacement(
                        context,
                        MaterialPageRoute(
                          builder: (context) => const OauthFinishProfilePage(),
                        ),
                      );
                    }
                  } else if (newState is AuthFailed) {
                    dPrint('Authentication failed: ${newState.exception}');
                  }
                  return null;
                },
              ),

Here's what this outputs when I login using Google:

flutter: Old state: Instance of 'Uninitialized', New state: Instance of 'SigningIn'
flutter: Signing in...
flutter: Old state: Instance of 'SigningIn', New state: Instance of 'UserCreated'
flutter: User created...
