Pagination Controller Call API On every Index Before Reaching End of the Page or on initializing the page

`Scaffold( 
    body: Column(children: [
        Search(),
        PagedListView<int, dynamic>(
            pagingController: controller.pagingCtrl,
            padding: EdgeInsets.only(bottom: 25.h),
            physics: const BouncingScrollPhysics(parent: AlwaysScrollableScrollPhysics()),
            builderDelegate: PagedChildBuilderDelegate<dynamic>(
                itemBuilder: (context, item, index) =>
                    _buildNewsCard(title: item?.title),
                firstPageProgressIndicatorBuilder: (_) => _buildNewsCardSkeleton(6),
                newPageProgressIndicatorBuilder: (_) => _buildNewsCardSkeleton(6)
                )
            )
      ],
    )
)`

Expecting to call API Only Once it reach the end of the page on scrolling

>Solution :

Wrap your pagination Widget with A Specific height.

    Scaffold( 
    body: Column(children: [
        _buildSearchAndFilterSection(),
         SizedBox(
          height: 90.w
          PagedListView<int, dynamic>(
            shrinkWrap: true,
            pagingController: controller.pagingCtrl,
            padding: EdgeInsets.only(bottom: 25.h),
            physics: const BouncingScrollPhysics(parent: AlwaysScrollableScrollPhysics()),
            builderDelegate: PagedChildBuilderDelegate<dynamic>(
                itemBuilder: (context, item, index) =>
                    _buildNewsCard(title: item?.title),
                firstPageProgressIndicatorBuilder: (_) => _buildNewsCardSkeleton(6),
                newPageProgressIndicatorBuilder: (_) => _buildNewsCardSkeleton(6)
                )
            )
        )
      ],
    )
)
