Freezed when method isn't recognized — help needed

[Mohamad-Ammis]

Hey folks 👋
I'm trying to use freezed for the first time to handle my Cubit states, but I can't access the generated methods like when, maybeWhen, etc. The error I get is:

---

✅ What I did

📄 My AuthState class

part of 'auth_cubit.dart';

@freezed
class AuthState with _$AuthState {
  const factory AuthState.initial() = _Initial;
  const factory AuthState.registerLoading() = _RegisterLoading;
  const factory AuthState.registerFailure({required String errMessage}) = _RegisterFailure;
  const factory AuthState.registerSuccess() = _RegisterSuccess;
}

📄 My `AuthCubit class

import 'dart:developer';
import 'package:delta_app/core/bloc/base_cubit.dart';
import 'package:delta_app/core/utils/service_locator.dart';
import 'package:delta_app/feature/auth/data/models/register_input_model.dart';
import 'package:delta_app/feature/auth/data/repos/auth_repository.dart';
import 'package:freezed_annotation/freezed_annotation.dart';

part 'auth_state.dart';
part 'auth_cubit.freezed.dart';

class AuthCubit extends BaseCubit<AuthState> {
  AuthCubit() : super(AuthState.initial());

  final AuthRepository authRepository = getIt.get<AuthRepository>();

  Future<bool> register({required RegisterInputModel model}) async {
    try {
      bool result = false;
      safeEmit(AuthState.registerLoading());

      final data = await authRepository.register(model: model);

      data.fold(
        (failure) => safeEmit(AuthState.registerFailure(errMessage: failure.errorMessage)),
        (success) {
          safeEmit(AuthState.registerSuccess());
          result = true;
        },
      );

      return result;
    } catch (e) {
      log('e: $e');
      safeEmit(AuthState.registerFailure(errMessage: e.toString()));
      return false;
    }
  }
}

😢 where i try to use when

BlocBuilder<AuthCubit, AuthState>(
  builder: (context, state) {
    return CustomButton(
      onTap: () {
        if (_key.currentState!.validate()) {
          log('validate');
        } else {
          setState(() {
            _autoValidateMode = AutovalidateMode.onUserInteraction;
            _key.currentState!.save();
          });
        }
      },
      gradient: kCommonGradinet,
      child: Text(
        "إنشاء حساب",
        style: Styles.style15Bold.copyWith(color: Colors.white),
      ),
    );
  },
);

what i've tried

remove all dependencies and add them again

delete pubspec.lock and run flutter clean ,flutter pub get then run build runner again

Ran flutter pub run build_runner build --delete-conflicting-outputs

add this to analysis_options.yaml

analyzer:
  errors:
    invalid_annotation_target: ignore

Tried hot restart and full rebuild

I think you're looking to file an issue against the freezed package? This repository is for discussions regarding the Dart language.

Sorry I didn't notice that.
