How to bottom align Button in the popup? - flutter

Question

How to bottom align button in the popup ?
here is my tried code, but its giving some space from bottom.
I have used listview to build up popup
onPressed: () {
// Navigator.of(context).pushNamed(homePageTag);
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
content: Form(
key: _formKey,
child: ListView(
shrinkWrap: true,//This tells items to be put in center
children: <Widget>[
FlatButton(
//padding: EdgeInsets.fromLTRB(0, 0, 0, 0),
color: appGreenColor,
child: Text("UPDATE", style: TextStyle(color: Colors.white)),
onPressed: () {
},
),
],
),
),
);
});
},
