DKStateEventFlutterExtension<T> extension

Flutter 原生拓展 适用于 StreamController<DKStateEvent

final submitEvent = StreamController<DKStateEvent<void>>();
void submitData() {
  submitEvent.triggerEvent(() async {
    // 执行提交操作
    await Future.delayed(Duration(seconds: 2));
  });
}
submitEvent.listenEvent(
  onLoading: () {
    // 显示加载中
  },
  onSuccess: (data, message) {
    // 处理成功
  },
  onError: (message, error, stackTrace) {
    // 处理错误
  },
);
