SBBHeaderbox class

The SBB Headerbox. Use according to documentation

To place over non scrollable screen content, place this Widget in a Stack with the content underneath.

@override
Widget build(BuildContext context) {
  return Stack(
    children: [
      _PageContentWidget(),
      SBBHeaderbox(
        title: 'Awesome Headerbox'
      ),
    ],
  );
}

This will lead to the expected behavior of the Headerbox.

See SBBSliverHeaderbox for a headerbox that behaves as expected in scrollable content, or SBBSliverFloatingHeaderbox for a fully dynamic version in scrolling contexts.
