  Widget build(BuildContext context) {
    return Container(
      padding: const EdgeInsets.all(20),

      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          const Text('line 1'),
          const SizedBox(height: 20),
          Row(

class _HomepageState extends State<Homepage> {
  @override

    return Scaffold(
      body: SafeArea(
        child: CustomScrollView(
          slivers: [
            const AdaptiveHeightSliverPersistentHeader(
              child: Header(),
              floating: true,
              needRepaint: true,
            ),
            SliverList(
              delegate: SliverChildBuilderDelegate(
                    (context, index) => Card(
                  margin: const EdgeInsets.all(20),
                  child: Padding(
                    padding: const EdgeInsets.all(20.0),
                    child: Text('card $index'),
                  ),
                ),
                childCount: 100,
              ),
            )
          ],
