flutter - cubit 的静态返回值不会发出新的状态

Question

我正在学习冻结的块，当我使用这个肘时不会发出新的状态。

class HomeCubit extends Cubit<HomeState> {
  HomeCubit() : super(HomeState.init());
     void addNewNoteButton() async {
        emit(state.copyWith(
          isOpenBottomSheet:true,
        ));
        }
}

但是当我使用这个肘部时，会发出新的状态：

class HomeCubit extends Cubit<HomeState> {
  HomeCubit() : super(HomeState.init());
     void addNewNoteButton({required bool isOpenBottomSheet}) async {
        emit(state.copyWith(
          isOpenBottomSheet:isOpenBottomSheet,
        ));
        }
}

状态代码是：

@freezed
abstract class HomeState with _$HomeState {
  const factory HomeState({
    required bool isOpenBottomSheet,
  }) = AddNewNoteClicked;

  factory HomeState.init() => HomeState(
        isOpenBottomSheet: true,
      );
}
