Getx Version:

get: ^5.0.0-release-candidate-9.2

Describe:

I used getx init to initialize the project and an error occurred when I ran it.

example:

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

import '../controllers/home_controller.dart';

class HomeView extends GetView<HomeController> {
  const HomeView({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('HomeView'),
        centerTitle: true,
      ),
      body: Column(
        children: [
          Container(
            width: Get.width,
            height: Get.height * 0.3,
            color: Colors.blue,
          ),
          Container(
            width: context.width,
            height: Get.height * 0.3,
            color: Colors.red,
          ),
          const Center(
            child: Text(
              'HomeView is working',
              style: TextStyle(fontSize: 20),
            ),
          ),
        ],
      ),
    );
  }
}

I'm facing the same. Any ETA on this issue?

PopInvokedWithResultCallback got introduced in flutter 3.24.0. So maybe updating your flutter version might help.
