i think because this plugin made only for desktop, you can handle UnimplementedError for mobile platforms

currently we must check platform

if(defaultTargetPlatform == TargetPlatform.macOS || defaultTargetPlatform == TargetPlatform.windows || defaultTargetPlatform == TargetPlatform.linux) {
  doWhenWindowReady(() {
      final initialSize = Size(600, 450);
      appWindow.minSize = initialSize;
      appWindow.size = initialSize;
      appWindow.alignment = Alignment.center;
      appWindow.show();
    });
}
