Flutter "showDialog" with Navigator.pop()

Question

I have problem with showDialog, when i press nothing happens but if i use Navigator.pushNamed(context, "/screen1") it works. I can not run Navigator.pop(context), it does not return any errors.

_showDialog(BuildContext context) {
return showDialog(
    context: context,
    builder: (BuildContext context) {
      return AlertDialog(
        title: new Text("Alert Dialog title"),
        actions: <Widget>[
          new FlatButton(
            child: new Text("Back"),
            onPressed: () {
              //Navigator.pushNamed(context, "/screen1");
              Navigator.pop(context);
            },
          ),
        ],
      );
    });}

In my build() :

IconButton(
iconSize: 30.0,
onPressed: () => _showDialog(context),
icon: Icon(
  Icons.clear,
  color: Colors.white,
 ),

)

Answer 1

had the same issue .having useRootNavigator: false, in showDialog params solved my issue .

Answer 2

Use pop() two times:-

Navigator.of(context).pop(); Navigator.of(context).pop();

Reason: first pop function dismiss the dialog and Second pop function close the screen
