如何在Flutter中处理聊天应用的滚动视图

ListView.builder(
  itemCount: messages.length,
  itemBuilder: (context, index) {
    return ListTile(
      title: Text(messages[index]),
    );
  },
)

CustomScrollView(
  slivers: <Widget>[
    SliverList(
      delegate: SliverChildBuilderDelegate(
        (context, index) {
          return ListTile(
            title: Text(messages[index]),
          );
        },
        childCount: messages.length,
      ),
    ),
  ],
)
