Bad state: GetIt: Object/factory with type <?> is not registered inside GetIt

Question

I'm learning Dependency Injection and Bloc. However, I have been facing an error that I cannot solve since last night. When I run the callback function in the GenderAsset widget, the application gives an error. When I use GenderCubit instead of Locator.sl(), the error goes away. I leave the code and pages here. I'd be happy if you help.

Gender StflW

 Widget build(BuildContext context) {
    return BlocProvider(
      create: (context) => Locator.sl<GenderCubit>(),
      child: const _GenderView(),
    );
  }

Gender Widget

  body: Center(
        child: Padding(
          padding: const ProductPadding.ten(),
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              GenderAsset(
                value: false,
                onChanged: (bool? value) {
                  print(context.read<GenderCubit>().genderValue); //error line
                },
                asset: AssetValue.female.value.lottie,
                gender: LocaleKeys.gender_fm.tr(),
                color: ProductColor().pink,
                icon: FontAwesomeIcons.venus,
              ),
            ],
          ),
        ),
      ),

GenderCubit

@injectable

      : _genderValue = genderValue ?? GenderValue.male,
        super(SelectGender(genderValue: genderValue));

  GenderValue? _genderValue;

  GenderValue get genderValue => _genderValue!;

  void changeGender2() {
    print("changeGender2");
  }

  void changeGender({GenderValue? newGender}) {
    _genderValue = newGender;
    emit(SelectGender(genderValue: _genderValue));
  }
}
