///A [CustomScrollView] lets you supply [slivers] directly to create various scrolling effects,
///such as lists, grids, and expanding headers. For example, to create a scroll view
///that contains an expanding app bar followed by a list and a grid, use a list of
///three slivers: [SliverAppBar], [SliverList], and [SliverGrid].
