SliverVisibility

The Stac SliverVisibility allows you to conditionally show or hide a sliver inside a CustomScrollView. When the sliver is not visible, it can either be completely removed from the scroll layout or replaced with another sliver, depending on the configuration. To know more about the SliverVisibility widget in Flutter, refer to the official documentation.
