DKStateEvent<T> class
sealed
DKStateEvent - 用于一次性事件操作的状态管理
适用场景：
- POST/PUT/DELETE 请求
- 提交操作（表单提交、按钮点击）
- 一次性事件（显示 Snackbar、导航跳转）
- 配合 StreamController 使用
通用逻辑请使用：
DKStateEventHelper工具类提供的静态方法DKStateEventFlutterExtension提供的扩展方法（用于 StreamController）
例如：
// 方式1: 使用扩展方法（推荐）
final submitEvent = StreamController<DKStateEvent<String>>();
submitEvent.triggerEvent(() async {
await Future.delayed(Duration(seconds: 2));
return 'Success';
});
final subscription = submitEvent.listenEvent(
onLoading: () => print('Loading...'),
onSuccess: (data, message) => print('Success: $data'),
onError: (message, error, stackTrace) => print('Error: $message'),
);
// 方式2: 使用工具类
await DKStateEventHelper.triggerEvent<String>(
onStateChange: (state) => controller.add(state),
event: () async => await fetchData(),
);
