如何使颤振容器滚动？

Question

我在Flutter中非常陌生，我想使注释后的容器能够滚动。 Nd我不想增加容器的高度如何实现此目的？除容器外，还有其他可使用的小部件吗？ 我真的需要帮助，我在全球的所有亲爱的朋友都请帮助我寻找解决方案。

String dropdownValue = 'One';
Widget _DropDown(BuildContext context) {
  return DropdownButton<String>(
    value: dropdownValue,
    icon: Icon(Icons.arrow_downward),
    iconSize: 24,
    elevation: 16,
    style: TextStyle(
        color: Colors.deepPurple
    ),
    underline: Container(
      height: 2,
      color: Colors.deepPurpleAccent,
    ),
    onChanged: (String newValue) {
      setState(() {
        dropdownValue = newValue;
      });
    },
    items: dropdownvalue
        .map<DropdownMenuItem<String>>((String value) {
      return DropdownMenuItem<String>(
        value: value,
        child: Text(value),
      );
    })
        .toList(),
  );
}

Widget _myListView(BuildContext context) {
  return ListView.separated(
    itemCount:initialAttendance == null ? 0 : initialAttendance.length,
    itemBuilder: (context, index) {
      return Card(

        elevation: 8.0,
        child: ClipPath(
          clipper: ShapeBorderClipper(shape: RoundedRectangleBorder(
