键盘打开时如何避免底部溢出（在警告对话框中）

Question

在这个屏幕上，每次我在警报文本字段中打开键盘时，我都会面临溢出。我已经尝试将 SingleChildScrollVIew 放在所有地方，但没有解决。这是具有警报对话框的组件：

Future<void> _showAlertDialog() async {
    return showDialog<void>(
      context: context,
      builder: (BuildContext context) {
        return AlertDialog(
          title: Text('Type the Name', textAlign: TextAlign.center,
            style: TextStyle(color: Colors.white)),
          content: TextField(
            controller: _nameController,
            keyboardType: TextInputType.text,
            textCapitalization: TextCapitalization.sentences,
          )
        );
      },
    );
  }

这是构建函数：

Widget build(BuildContext context) {
    return Scaffold(
      resizeToAvoidBottomPadding: false,
      body: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          TableCalendar(//default code),
            Divider(),
            _showList(),
          ],
        ),

      floatingActionButton: FloatingActionButton(
        child: Icon(Icons.add, color: Colors.white,),
        onPressed: () => _showCity(context) 
      ),
    );
  }

_showAlertDialog 在 _showCity 中被调用（参见 build > floating action button > onpressed）

_showCity:

_showCity(BuildContext context){
  _showAlertDialog();
}

但在所有尝试之后，每次我点击 _showAlertDialog 中的 textField 并打开键盘时，都会抛出错误：

A RenderFlex overflowed by 33 pixels on the bottom.

我该如何处理？

更新 _showList:

Widget _showList(){
    return ListView.builder(

        scrollDirection: Axis.vertical,
        shrinkWrap: true,
        itemCount: _sEv.length,
        itemBuilder: (BuildContext context, int index) {
          return GestureDetector(
            onTap: () {
              
            },
            child: Dismissible(
              child: ListTile(
                leading: //loremipsum,
                title: //blablabla,
                subtitle: //dolorsit,
                ),
              ),
              key: UniqueKey(),
              direction: DismissDirection.startToEnd,
              background: Container(
                alignment: AlignmentDirectional.centerEnd,
                color: Colors.redAccent,
                child: Icon(Icons.delete_rounded),
              ),
              onDismissed: (DismissDirection direction) {
                setState(() {
                  //my irrelevant code
                });
            }
          ),);
        },
      );
  }

只需将此页面的正文包裹在 SingleChildScrollView 中即可。

Widget build(BuildContext context) {
   return SingleChildScrollView(
      child: Scaffold(
         resizeToAvoidBottomPadding: false,
         body: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [ TableCalendar(
              //default code), 
              Divider(), _showList(),
            ],
         ),
         floatingActionButton: FloatingActionButton(
            child: Icon(Icons.add, color: Colors.white,),
            onPressed: () => _showCity(context)
         ),
      ),
   );
}
