Minimal code to reproduce:

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

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await windowManager.ensureInitialized();
  runApp(const MyApp());
}

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

  @override
  createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> with WindowListener {
  late AppLifecycleListener listener;

  @override
  void initState() {
    super.initState();

    windowManager.addListener(this);
    _initWindowManager();
  }

  @override
  void onWindowClose() async {
    bool isPreventClose = await windowManager.isPreventClose();

    if (isPreventClose) {
      windowManager.destroy();
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: Scaffold(appBar: AppBar()));
  }

  void _initWindowManager() async {
    await windowManager.setPreventClose(true);
    setState(() {});
  }

  @override
  void dispose() {
    listener.dispose();
    windowManager.removeListener(this);
    super.dispose();
  }
}

non-issue

[ujwalbasnet1]

@damywise can you explain in detail what you mean by non-issue?

was it not reproducible?

[damywise]

The error is not an issue, literally. There's no problem there. No side effects. It's normal. Happens all the time. Just ignore it.
Unless there's an unexpected problem/behavior which you haven't specified.

It doesn't seem to be caused by window_manager.
