如何用GetX设置displayName？

import 'package:flutter/material.dart';
import 'package:get/get.dart';

class MyController extends GetxController {
  final count = 0.obs;
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('GetX Example'),
      ),
      body: Center(
        child: GetBuilder<MyController>(
          init: MyController(),
          name: 'myController', // 设置displayName
          builder: (controller) {
            return Text(
              'Count: ${controller.count}',
              style: TextStyle(fontSize: 24),
            );
          },
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          Get.find<MyController>().count++;
        },
        child: Icon(Icons.add),
      ),
    );
  }
}

void main() {
  runApp(GetMaterialApp(
    home: MyHomePage(),
  ));
}
