PagedSliverBuilder<PageKeyType, ItemType> class
Assists the creation of infinitely scrolled paged sliver widgets.
Combines a PagingController with a PagedChildBuilderDelegate and calls the supplied loadingListingBuilder, errorListingBuilder or completedListingBuilder for filling in the gaps.
For ordinary cases, this widget shouldn't be used directly. Instead, take a look at PagedSliverList, PagedSliverGrid, PagedGridView and PagedListView.
