Flutter Getx route argument data is lost when hot reload

Question might be misleading, but I'm currently working on a project where I use Get.toNamed a lot and I'm sending some data every time. But, when I hot reload the changes I get

════════ Exception caught by widgets library ═══════════════════════════════════
type 'Null' is not a subtype of type `int` 

and I'm changing route with

onTap: () {
    print(_sliderValue);
    Get.toNamed('/stations/detail/booking', arguments: {
        'duration': _sliderValue,
    });
},

Edit:

As I have mentioned, I'm using Stateless Widget to for that screen, so the code I have is:

class ConnectorScreen extends StatelessWidget {
  const ConnectorScreen({super.key});

  @override
  Widget build(BuildContext context) {
    final Map<String, dynamic> arguments =
        Get.arguments as Map<String, dynamic>;
    final Connector connector = arguments['connectors'];

which gives error that type 'Null' is not a subtype of type Connector once I hot reload.

Is there any proper way of not losing data while routing between pages or hot reload?

Im always using Get.toNamed to send arguments but never found issue like this soo maybe you can try this

You can route to page by SecondPage.show(somethingId : 'id#0');

class SecondPage extends StatelessWidget {
  static String get name => '/second-page';

  const SecondPage({Key? key}) : super(key: key);

  static Future<void> show({
    required String somethingId,
  }) async {
    await Get.toNamed(
      name,
      arguments: {
        'somethingId': somethingId,
      },
    );
  }

  @override
  Widget build(BuildContext context) {
   ....
  }

and in controller

class SecondPageController extends GetxController {
  @override
  void onInit() async {
    somethingId.value = Get.arguments['somethingId'] ?? '';

    super.onInit();
  }

  final somethingId = ''.obs;
}
