Future getMorePostList({String blogSlug}) async {
    scrollController.addListener(() async {
      if (scrollController.position.maxScrollExtent ==
          scrollController.position.pixels) {
        skipCount.value++;
        var response = await _cmsKitRepository.getPostListWithDetail(blogSlug,
            skipCount: skipCount.value);
        blogPostPublicDtoList.addAll(response.items);
        if (response.items.length == 0) {
          _lastPage.value = true;
        }
      }
    });
  }
