Get.back() not working in Get.Dialog using GetMaterialApp builder property

[ptawde95]

Describe the bug I have used the Default layout using material App for all pages, so i have a Get.Dialog() in which I have used a container to show a dialog box, but on the click of the button Get.back() is not working due to which i am not able to close dialog box on the button click.

Please refer to the below examples for the details with Screenshots and error description

Example:

main.dart

import 'package:flutter/material.dart';
import 'package:flutter_application_1/defaultview.dart';
import 'package:get/get.dart';

void main() {
  runApp(GetMaterialApp(
    initialRoute: '/task',
    builder: (context, child) => DefaultView(child: child),
    getPages: [
      GetPage(
        name: '/task',
        page: () => Container(
          child: Center(
            child: RaisedButton(
              child: Text('Open Dialog'),
              onPressed: () => Get.defaultDialog(
                title: 'Login Failure',
                radius: 5.0,
                middleText: "result",
                actions: [
                  RaisedButton(
                    onPressed: () {
                      print("test");
                      Get.back();
                    },
                    child: Text(
                      "OK",
                      style: TextStyle(color: Colors.white),
                    ),

            ),
          ),
        ),

Why you use MaterialApp inside GetMaterialApp?

[ptawde95]

I had referred the issue raised by one of my colleague for Use of Popupbutton which requires a material App in which he suggested we can use Material App inside a material app which does not create the Material App twice. https://github.com/jonataslaw/getx/issues/729

@ghprod Any updates..?

[danbo]

Try this:

Get.back(closeOverlays: true);

Tested on get: 4.2.0

[rahul12hisar]

Do not use Material App in GetMaterial App, and try to create a scaffold before creating dialog

[iamtechmanish]

try this : Navigator.of(Get.overlayContext!, rootNavigator: true).pop();

[bijon95]

Try this:

Get.back(closeOverlays: true);

Tested on get: 4.2.0

Its working in windows
