UseRequestResult<TData, TParams> class

useRequest 的返回结果对象

包含请求状态和操作方法，提供完整的请求控制能力。

状态属性

操作方法

示例

final result = useRequest<User, int>(fetchUser);

// 根据状态渲染 UI
if (result.loading) {
  return CircularProgressIndicator();
}

if (result.error != null) {
  return Text('Error: ${result.error}');
}

return Text('User: ${result.data?.name}');
