Lost connection to device. (on ubuntu 22.04 LTS)

[hosseinvejdani]

when i want to use window_manager package in my flutter app in ubuntu 22.04 os, i got this message:
Lost connection to device.
and suddenly the opened app windows close!

my code is here:

import 'package:get/get.dart';
import 'package:flutter/material.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';
import 'package:window_manager/window_manager.dart';
import 'src/core/core.dart';
import 'src/view/view.dart';


void main() async {
  // ====================== new ========================
  WidgetsFlutterBinding.ensureInitialized();
  await windowManager.ensureInitialized();

  WindowOptions windowOptions = WindowOptions(
    size: Size(800, 600),
    center: true,
    backgroundColor: Colors.transparent,
    skipTaskbar: false,
    titleBarStyle: TitleBarStyle.hidden,
  );

  windowManager.waitUntilReadyToShow(windowOptions, () async {
    await windowManager.show();
    await windowManager.focus();
  });

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    //Set the fit size (Find your UI design, look at the dimensions of the device screen and fill it in,unit in dp)
    return ScreenUtilInit(
      designSize: designSize,
      minTextAdapt: true,
      splitScreenMode: true,
      builder: (context, _) {
        return GetMaterialApp(
          debugShowCheckedModeBanner: false,
          initialRoute: RoutesName.portConfigScreen,
          getPages: AppPages.pages,
        );
      },
    );
  }
}

but if i comment this part, the app run healthy without setting my size properly:

 windowManager.waitUntilReadyToShow(windowOptions, () async {
    await windowManager.show();
    await windowManager.focus();
  })

and finally this is my flutter doctor result:

I also encountered this problem
Mainly because of the center property
