when i add or remove item from i want to update widget based on state but state not updating but if i use a extra variable bool isChangeInList for update list it’s working
and when i emit like below it’s working fine

how to update list changes in ui without extra variable

cubit.dart

      if(state.selectedFilterCategories.contains(categoryId)){
        state.selectedFilterCategories.remove(categoryId);
      }else{
       state.selectedFilterCategories.add(categoryId);
      }
      emit(state.copyWith(selectedFilterCategories:List.of(state.selectedFilterCategories)));
     } 

cubit_state.dart

    @Freezed(makeCollectionsUnmodifiable: false)
       class OfferState with _$OfferState {
         factory OfferState.initial({
           required List<int> selectedFilterCategories,
         }) = _Initial;
       }
