how to implement lazy loading inside nested scroll view in flutter

Question

i want to add lazy loading for my app but when i put the new controller. the controller didn't work with the NestedScrollView that i've made.
my new controller:

final controller = ScrollController();

in my initstate:

controller.addListener(() {
      if (controller.position.maxScrollExtent == controller.offset) {
        getStoryUser();
      }

and i put the controller into list view but its didn't work with the NestedScrollView that i've mentioned earlier. any solution for this matter? any help will be valuable thank you.

Attach this _scrollController with your scrollview

if ((_scrollController.position.pixels >
        _scrollController.position.maxScrollExtent - 20)) {
      if (_isLoading || _loadMore || ((_media.media?.length ?? 0) < 30)) {
        return;
      }
      _pageNumber++;
      _loadMore = true;
      if (mounted) setState(() {});
        await _loadData();

      _loadMore = false;
      if (mounted) setState(() {});
    }
