android - 如何在不占用更多空间的情况下在末端抽屉中添加可滚动 ListView ？

Question

这是我的主页，有两个抽屉，最后抽屉我必须显示通知列表。我尝试使用 NestedScrollView，但它创建了一个我不需要的 SliverAppBar。我只需要滚动列表数据并保持标题固定。我不想使用消耗更多空间的 DrawerHeader。

    class HomeScreen extends StatefulWidget {
      @override
      State<StatefulWidget> createState() {
        return new HomeScreenState();
      }
    }

    class HomeScreenState extends State<HomeScreen>{
      ScrollController _controller = new ScrollController();
      final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();

      void _logout() async {
        var db = new DatabaseHelper();
        await db.deleteUsers();
      }

      @override
      Widget build(BuildContext context) {
        return Scaffold(
          key: _scaffoldKey,
          endDrawer: new Drawer(
            child: new ListView(
              children: <Widget>[
                new ListTile(
                  title: new Text('Notifications',
                  style: new TextStyle(
                  fontSize: 24.0,
                  fontWeight: FontWeight.bold,
                ),
                textAlign: TextAlign.center,
              ),
            ),
            // List of notifications shld be done here...
            new CustomScrollView(
              shrinkWrap: true,
              controller: _controller,
              slivers: <Widget>[
                new SliverPadding(
                  padding: const EdgeInsets.all(20.0),
                  sliver: new SliverList(
                    delegate: new SliverChildListDelegate(
                    <Widget>[
                      const Text('I\'m dedicating every day to you'),
                      const Text('Domestic life was never quite my style'),

                      const Text('Domestic life was never quite my style'),
                      const Text('When you smile, you knock me out, I fall apart'),
                      const Text('And I thought I was so smart'),

您可以只使用 Column 和其中的 ListView

endDrawer: Drawer(
          child: Column(
            children: <Widget>[
              new Text('Notifications',
                  style: new TextStyle(
                  fontSize: 24.0,
                  fontWeight: FontWeight.bold,
                ),
                textAlign: TextAlign.center,
              ),
              Flexible(
                child: ListView(
                  children: List.generate(20, (i)=>ListTile(
                    title: Text('Notification $i'),
                  )),
                ),
              )
            ],
          ),
        ),
