I am trying to log in using firebase using the Google Login in and trying to register a username and account. Basically any authentication process i try to do i get the following error:

Unhandled Exception: type ‘List<Object?>’ is not a subtype of type ‘PigeonUserDetails?’ in type cast

Here is the code for my google login in and registering using username and password:

class LoginAccountBloc extends Bloc<LoginAccountEvent, LoginAccountState> {
  LoginAccountBloc() : super(LoginAccountInitial()) {
    on<LoginAccountSubmitted>(
      (event, emit) async {
        emit(LoginAccountSubmitting());
        try {
          await FirebaseAuth.instance.signInWithEmailAndPassword(
            email: event.email,
            password: event.password,
          );
          emit(LoginAccountSuccessful());
        } on FirebaseAuthException catch (e) {
          if (e.code == 'user-not-found') {
            emit(LoginAccountFailure('No user found for that email.'));
          } else if (e.code == 'wrong-password') {
            emit(LoginAccountFailure('Wrong password provided for that user.'));
          } else {
            emit(LoginAccountFailure(e.toString()));
          }
        }
      },
    );
  }
}



class RegisterAccountBloc
    extends Bloc<RegisterAccountEvent, RegisterAccountState> {
  RegisterAccountBloc() : super(RegisterAccountInitial()) {
    on<RegisterAccountSubmitted>(
      (event, emit) async {
        print(event.username);
        print(event.email);
        print(event.password);
        emit(RegisterAccountSubmitting());
        if (event.username.isEmpty ||
            event.email.isEmpty ||
            event.password.isEmpty) {
          emit(RegisterAccountFailure("All fields are required."));
          return;
        }
        print('All fields are written');
        try {
          // Step 1: Create a new user with Firebase Authentication

          final credential =
              await FirebaseAuth.instance.createUserWithEmailAndPassword(
            email: event.email,
            password: event.password,
          );
          print('Added Credentials to FirebaseAuth');
        } on FirebaseAuthException catch (e) {
          if (e.code == 'weak-password') {
            emit(RegisterAccountFailure('The password provided is too weak.'));
          } else if (e.code == 'email-already-in-use') {
            emit(RegisterAccountFailure(
                'The account already exists for that email.'));
          } else {
            emit(RegisterAccountFailure(e.toString()));
          }
        }

        try {
          CollectionReference users =
              FirebaseFirestore.instance.collection('User');
          print("Trying to add");
          await users.add({
            'username': event.username,
            'email': event.email,
            'password': event.password
          });
          print("User Created");
          emit(RegisterAccountSuccess());
        } catch (error) {
          emit(RegisterAccountFailure(error.toString()));
        }
      },
    );
  }
}

I tried to debug for hours but no signs of any change at this point. It was working before firebase started showing this message in the authentication tab.

==> Cross origin redirect sign-in is no longer supported in many browsers. Update your app to ensure your users can continue to sign into your app.

  1. there is nothing wrong with your code, this is a firebase auth issue, I was facing the same, all did was update firebase_auth and firebase_core to the latest version, and re-run the app, that solved the issue in my case.

  2. i am getting a similar problem also: W/System (11937): Ignoring header X-Firebase-Locale because its value was null.

    [log] Error during sign-in: type ‘List<Object?>’ is not a subtype of type ‘PigeonUserDetails?’ in type cast. i doest log in, however, then it throws this error. On my emulator, i get a popup saying my credentials were incorrect even though they are.
