flutter - 如何将滚动发光放在 sliverList 而不是 customScrollView 中？

Question

发光就像整个屏幕是一个列表。有什么方法可以将发光放在应用栏下方？（编辑：不失appbar的浮动效果）

CustomScrollView(
      slivers: <Widget>[
        SliverAppBar(
          title: Text('Home Scree'),
          floating: true,
          leading: Icon(Icons.alarm),
        ),
        SliverList(
          delegate: SliverChildBuilderDelegate(
            (ctx, i) {
              return Column(
                children: <Widget>[
                  ProductCard(),
                  Divider(
                    height: 0,
                    thickness: 1,
                  ),
                ],
              );
            },
            childCount: 10,
          ),
        ),
      ],
    ),

也许你可以尝试使用NestedScrollView，像这样：

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: NestedScrollView(
        headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
          return [SliverAppBar(
            leading: Icon(Icons.alarm),
            title: Text('Home Scree'),
            expandedHeight: kToolbarHeight,
            floating: true,
          )];
        },
        body: ListView.builder(
          padding: EdgeInsets.zero,
            itemCount: 10,
            itemBuilder: (context, index) {
              return Column(
                children: <Widget>[
                  ProductCard(),
                  Divider(
                    height: 0,
                    thickness: 1,
                  ),
                ],
              );
            }),
      ),
    );
  }
