PagedListView<PageKeyType, ItemType> class

Paged ListView with progress and error indicators displayed as the last item.

To include separators, use PagedListView.separated.

Wraps a PagedSliverList in a BoxScrollView so that it can be used without the need for a CustomScrollView. Similar to a ListView.
