在Flutter中的ListView中滚动或“嵌套滚动”的问题

NestedScrollView(
  headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
    return <Widget>[
      SliverAppBar(
        title: Text("NestedScrollView Example"),
        expandedHeight: 200.0,
        flexibleSpace: FlexibleSpaceBar(
          background: Image.network(
            "https://example.com/image.jpg",
            fit: BoxFit.cover,
          ),
        ),
      ),
    ];
  },
  body: ListView.builder(
    itemCount: 100,
    itemBuilder: (BuildContext context, int index) {
      return ListTile(
        title: Text("Item $index"),
      );
    },
  ),
);
