Dismissing a Cupertino dialogue action Flutter

Question

While dismissing a presented Cupertino alert dialogue action using the explained method my entire screen gets popped of and the alert dialogue stays on the screen. This is my code.

if (deviceList.isEmpty){

      var alert = new CupertinoAlertDialog(
        title: new Text("Alert"),
        content: new Text("There was an error signing in. Please try again."),
        actions: <Widget>[
          new CupertinoDialogAction(
              child: const Text('Discard'),
              isDestructiveAction: true,
              onPressed: () { Navigator.pop(context, 'Discard'); }
          ),
          new CupertinoDialogAction(
              child: const Text('Cancel'),
              isDefaultAction: true,
              onPressed: () { Navigator.pop(context, 'Cancel'); }
          ),
        ],
      );
      showDialog(context: context, child: alert);
    }

Is there anything wrong in what I am doing? I cant find any other solution to dismiss the alert dialogue. Please help.

Answer 1

In this case, you need to specify the rootNavigator to of() :

Navigator.of(context, rootNavigator: true).pop("Discard");

Check the implementation proposed in the documentation
