如何使用GetX包获取Flutter中的当前语言环境？

dependencies:
  flutter:
    sdk: flutter
  get: ^4.1.4
  get_storage: ^2.0.3

import 'package:get/get.dart';
import 'package:get_storage/get_storage.dart';

void main() async {
  await GetStorage.init(); // 初始化GetStorage

  // 获取当前语言环境
  String currentLocale = GetStorage().read('locale') ?? 'en'; // 默认为英文

  runApp(MyApp(currentLocale));
}

class MyApp extends StatelessWidget {
  final String currentLocale;

  MyApp(this.currentLocale);

  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      translations: MyTranslations(), // 自定义翻译文件
      locale: Locale(currentLocale), // 设置当前语言环境
      fallbackLocale: Locale('en'), // 设置默认语言环境
      home: HomeScreen(),
    );
  }
}

class MyTranslations extends Translations {
  @override
  Map<String, Map<String, String>> get keys => {
        'en': {
          'hello': 'Hello',
          'world': 'World',
        },
        'zh': {
          'hello': '你好',
          'world': '世界',
        },
      };
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('GetX Language Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('当前语言环境：${Get.locale.languageCode}'),
            Text('翻译示例：${'hello'.tr} ${'world'.tr}'),
          ],
        ),
      ),
    );
  }
}
