Lost connection to device when MenuItem is clicked

I am facing some issues that flutter always terminate app running with Lost connection to device. when I tap any MenuItem.

Since I do not want to show any window, I do not use win.show() in my doWhenWindowReady initialization function. Here is the snippet of my code.

import 'package:bitsdojo_window/bitsdojo_window.dart';
import 'package:flutter/material.dart' hide MenuItem;
import 'package:system_tray/system_tray.dart';

import 'package:url_launcher/url_launcher.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(const MenuBar());
}

class MenuBar extends StatefulWidget {
  const MenuBar({Key? key}) : super(key: key);

  @override
  State<MenuBar> createState() => _MenuBarState();
}

class _MenuBarState extends State<MenuBar> {
  final SystemTray _tray = SystemTray();
  final AppWindow _appWindow = AppWindow();
  final Uri _url = Uri.parse('https://google.com/');

  @override
  void initState() {
    super.initState();
    doWhenWindowReady(() {
      initSystemTray();
      // final win = appWindow;
      // const initialSize = Size(600, 450);
      // win.minSize = initialSize;
      // win.size = initialSize;
      // win.alignment = Alignment.center;
      // win.title = "How to use system tray with Flutter";
      // win.show();
    });
  }

  @override
  void dispose() {
    super.dispose();
  }

  Future<void> initSystemTray() async {
    final menu = [
      MenuItem(
          label: 'Login',
          onClicked: () async {
            print('clicked');
            _launchUrl();
          }),
      MenuSeparator(),
      MenuItem(label: 'About', onClicked: _appWindow.hide),
      MenuSeparator(),
      MenuItem(label: 'Quit', onClicked: _appWindow.close),
    ];

    await _tray.initSystemTray(title: '', iconPath: 'assets/Logo.png');

    // assign tray menus
    await _tray.setContextMenu(menu);

    _tray.registerSystemTrayEventHandler((eventName) {
      debugPrint("eventName: $eventName");
      if (eventName == "lefMouseDown") {
      } else if (eventName == "leftMouseUp") {
        _tray.popUpContextMenu();
      }
    });
  }

  @override
  Widget build(BuildContext context) {
    return Container();
  }

  void _launchUrl() async {
    if (!await launchUrl(_url)) throw 'Could not launch $_url';
  }
}

When I initialize win.show(); in my first init function, flutter doesn't terminate my app running and works as desired. However, since I do not need any window UI and just want to use the system tray. Any way to achieve this or a solution?
