SliverStickyHeader

You can place one or multiple SliverStickyHeaders inside a CustomScrollView.

SliverStickyHeader(
  header: Container(
    height: 60.0,
    color: Colors.lightBlue,
    padding: EdgeInsets.symmetric(horizontal: 16.0),
    alignment: Alignment.centerLeft,
    child: Text(
      'Header #0',
      style: const TextStyle(color: Colors.white),
    ),
  ),
  sliver: SliverList(
    delegate: SliverChildBuilderDelegate(
      (context, i) => ListTile(
            leading: CircleAvatar(
              child: Text('0'),
            ),
            title: Text('List tile #$i'),
          ),
      childCount: 4,
    ),
  ),
);

SliverStickyHeader.builder

If you want to change the header layout during its scroll, you can use the SliverStickyHeader.builder constructor.

The example belows changes the opacity of the header as it scrolls off the viewport.

SliverStickyHeader.builder(
  builder: (context, state) => Container(
        height: 60.0,
        color: (state.isPinned ? Colors.pink : Colors.lightBlue)
            .withOpacity(1.0 - state.scrollPercentage),
        padding: EdgeInsets.symmetric(horizontal: 16.0),
        alignment: Alignment.centerLeft,
        child: Text(
          'Header #1',
          style: const TextStyle(color: Colors.white),
        ),
      ),
  sliver: SliverList(
    delegate: SliverChildBuilderDelegate(
      (context, i) => ListTile(
            leading: CircleAvatar(
              child: Text('0'),
            ),
            title: Text('List tile #$i'),
          ),
      childCount: 4,
    ),
  ),
);
