颤抖-在列表视图构建器中滚动列表视图

Question

我有一个“过滤器”，下面是足球比赛的列表。我用ListView包装“ Filter and” listview builder”（这样就解决了blablabla下的重载问题）。但是，当您正常滚动时，会有一些奇怪的事情。滚动到无效的列表。只有一个“发光效果”，但是我从上面的“过滤器菜单”滚动，该滚动有效。如何使滚动正常运行？

我的代码片段：

Widget _buildListView(FixtureModel model, BuildContext context) {
    return Container(
        child: model.getFixturesCount() == 0
            ? Center(child: Text('No fixtures found'))
            : ListView(
                shrinkWrap: true,
                children: <Widget>[
                  Column(
                    children: <Widget>[
                      Row(
                        mainAxisAlignment: MainAxisAlignment.spaceBetween,
                        children: <Widget>[
                          Container(
                              padding: EdgeInsets.only(left: 10.0),
                              child: InkWell(
                                onTap: () => _onTap(context),
                                child: Container(
                                    margin:
                                        EdgeInsets.only(top: 5.0, bottom: 5.0),
                                    child: Row(
                                      children: <Widget>[
                                        Container(
                                            padding: EdgeInsets.only(left: 5.0),
                                            child:
                                                Icon(FontAwesomeIcons.github)),
                                        Container(
                                          padding: EdgeInsets.only(left: 15.0),
                                          child: Text(

在您的ListView中添加：

shrinkWrap: true,
physics: NeverScrollableScrollPhysics(),

要从ListView中取出过滤器：remove physics: NeverScrollableScrollPhysics(), then in ListView

body: Column(
                  children: <Widget>[
                     Filter(),
                     Expanded(
                        child: ListView()
                     ),
                ]
            )
