alertDialog won't appear in flutter - flutter

Question

I have a list item when long pressed executes _selectionAlert which have two buttons one for delete and one for edit(refer image). Delete works fine but when I press on edit it should execute _editAlert which should show another alertDialog but when I click it nothing happens what's the problem here?
This is responsible to show alert dialog in _selectionAlert
TextButton( // refer code bellow
child: Text('Edit', style: TextStyle(color: Colors.grey)),
onPressed: (){
_editAlert();
Navigator.of(context).pop();
},
)
This bellow code runs when item is long pressed:
void _selectionAlert(){
var selItem = AlertDialog(
title: Text('What you want to do?'),
content: Column(
mainAxisSize: MainAxisSize.min,
children: [
TextButton( // ignore this it is for deletion this works fine
child: Text('Delete', style: TextStyle(color: Colors.red)),
onPressed: (){
_deleteItem();
Navigator.of(context).pop();
},
),
TextButton(
child: Text('Edit', style: TextStyle(color: Colors.grey)),
onPressed: (){
_editAlert(); // this line should call _editAlert
Navigator.of(context).pop();
},
)
],
),
);
showDialog(
context: context,
builder: (BuildContext context){
return selItem;
}
);
}
Representation of above code:
void _editAlert(){ // edit alertDialog
var editItem = AlertDialog(
title: Text('Edit'),
content: Column(
mainAxisSize: MainAxisSize.min,
children: [
TextField(
decoration: InputDecoration(
hintText: 'Edit Item',
),
controller: addeditem,
),
TextButton(
child: Text('Done'),
onPressed: (){
_editItem();
Navigator.of(context).pop();
}
)
],
),
);
showDialog(
context: context,
builder: (BuildContext context){
return editItem;
}
);
}
PS: edit button is of grey color the button surely is clickable and I am testing on google chrome.

Try to add return statement at your _editAlert method
_editAlert(){ // edit alertDialog
var editItem = AlertDialog(
title: Text('Edit'),
content: Column(
mainAxisSize: MainAxisSize.min,
children: [
TextField(
decoration: InputDecoration(
hintText: 'Edit Item',
),
controller: addeditem,
),
TextButton(
child: Text('Done'),
onPressed: (){
_editItem();
Navigator.of(context).pop();
}
)
],
),
);
return showDialog( //like that
context: context,
builder: (BuildContext context){
return editItem;
}
);
}
Also your way is right,you can use poping for close previous pop up.
