window_manager [LINUX] 虚拟机，Ubuntu，按照readme文件指引添加代码后，启动应用失败

环境： Flutter 3.0.5 Dart 2.17.6

代码如下

import 'package:window_manager/window_manager.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  // Must add this line.
  await windowManager.ensureInitialized();

  const windowOptions = WindowOptions(
    size: Size(600, 600),
    center: true,
    backgroundColor: Colors.transparent,
    skipTaskbar: false,
    titleBarStyle: TitleBarStyle.hidden,
  );
  windowManager.waitUntilReadyToShow(windowOptions, () async {
    await windowManager.show();
    await windowManager.focus();
  });

  runApp(const MyApp());
}

控制台报错：

请问这是什么原因
