flutter web cursor not changing immediately

Question

I am trying to change the cursor when I hover or click some button but it only change if I refresh the page it's very weird I found the same problem with this website https://flutteranimations.netlify.app/#/

I use MouseRegion Widget wrap with an entire body but not working I also create a stateless class for the button and wrap it with MouseRegion same problem nothing works unless I right-click the button and popup the menu it changes

this is the code I use

class DesktopPage extends HookWidget {
  DesktopPage({Key? key}) : super(key: key);

  String logo = "images/logo.png";
  String trash = "images/trash.png";
  String file = "images/file.png";
  String cepc = "images/cepc.png";
  String doc = "images/doc.png";

  DateTime now = DateTime.now();

  @override
  Widget build(BuildContext context) {
    var isHover = useState<bool>(false);

    return Scaffold(
        backgroundColor: Color(0xff008282),
        bottomNavigationBar: Container(
          decoration: BoxDecoration(color: const Color(0xffC0C0C0), boxShadow: [
            BoxShadow(
                color: Color.fromARGB(255, 255, 255, 255),
                offset: Offset(-1.5, -1.5)),
          ]),
