如何在getx中将变量重置为默认值？

import 'package:get/get.dart';

class MyController extends GetxController {
  var myVariable = 'default value'.obs;

  void resetVariable() {
    myVariable.value = 'default value';
  }
}

class MyPage extends StatelessWidget {
  final MyController myController = Get.put(MyController());

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            myController.resetVariable();
          },
          child: Text('Reset Variable'),
        ),
      ),
    );
  }
}
