How to avoid bottom overflow when keyboard open (in alert dialog) - flutter

Question

In this screen i'm facing overflow every time I open keyboard in the alert text field. I already tried to put SingleChildScrollVIew in all the places and it didn't resolve. This is the component which have the alertdialog:
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,
)
);
},
);
}
This is the build function:
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)
),
);
}
The _showAlertDialog is called inside _showCity (see build > floating action button > onpressed)
_showCity:
_showCity(BuildContext context){
_showAlertDialog();
}
But after all attempts, every time I hit the textField in _showAlertDialog and it opens the keyboard, it throws an error:
A RenderFlex overflowed by 33 pixels on the bottom.
How can I handle that?
Update
_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
});
}
),);
},
);
}

Just wrap the body of this page in SingleChildScrollView like this.
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)
),
),
);
}
