RenderSliverFloatingPinnedPersistentHeader constructor
Creates a sliver that shrinks when it hits the start of the viewport, then stays pinned there, and grows immediately when the user reverses the scroll direction.
Implementation
RenderSliverFloatingPinnedPersistentHeader({
RenderBox child,
FloatingHeaderSnapConfiguration snapConfiguration,
}) : super(child: child, snapConfiguration: snapConfiguration);
