AuthState: Instance of 'Uninitialized': need help using social sign-in methods

[khanliKU]

Hello,

I am using Flutter and Firebase to build my mobile app. Although I followed the guides, I am stuck and need help using social sign-in methods. Can you help me figure out the problem? Or is there a bug?

1. I set up Sign-in Methods in my Firebase project.

2. I ran flutterfire configure
3. I initialized Firebase as follows:

  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

  FirebaseUIAuth.configureProviders([
    EmailAuthProvider(),
    GoogleProvider(
      clientId: googleClientID,
    ),
    TwitterProvider(
      apiKey: twitterApiKey,
      apiSecretKey: twitterSecret,
    ),
  ]);

4. I am using the sign-in screen provided by firebase_ui_auth as follows:

          return SignInScreen(
            actions: [
              AuthStateChangeAction((BuildContext context, AuthState state) {
                SimpleLogger().config('AuthState: $state');
              }),
            ],
          );

5. When I click on the Sign-in with Google or Sign-in with Twitter, I get the following output:
   AuthState: Instance of 'Uninitialized'
