How can you properly implement infinite scrolling or pagination within a sliver based scroll view, automatically loading additional new content as a user actively scrolls further down toward the very bottom of the currently loaded list?

Implementing infinite scrolling within a sliver based scroll view typically involves properly listening to the ScrollController's own current scroll position, actively checking whenever that current position genuinely gets sufficiently close to the very bottom edge of the currently already loaded content, and then automatically triggering a request to load and properly append an entirely new additional page of further content onto your existing underlying data list, then correctly and automatically updating your SliverList so it now properly displays this newly appended additional content seamlessly as part of that exact same single continuous ongoing scroll.

scrollController.addListener(() {
  if (scrollController.position.pixels >= scrollController.position.maxScrollExtent - 200) {
    loadNextPage();
  }
});
