如何让 Flutter 应用程序提供 Facebook 的点赞。
我编写了此代码以使用 flutter 和 firebase 在 Facebook 上点赞。

但是当我尝试完成它时总是显示此错误。我的代码没有错误，我认为它是 faceboob-gragh-api 问题

获取点赞时出错：{\'error\'：{\'message\':\'不支持获取请求。ID 为“okxaHZh7gPfu3rev”的对象不存在，由于缺少权限而无法加载，或者不支持此操作。请阅读 Graph API 文档：https://developers.facebook.com/docs/graph-api\',\'type\':\'GraphMethodException\',\'code\'：100,\'error_subcode\'：33,\'fbtrace_id\':\'APZvYG8aMW6bU-fewHOzPPT\'}}

并且这个错误也

错误异常：无法点赞帖子：不支持帖子请求。ID 为“okxaHZh7gPfu3rev”的对象不存在，由于缺少权限而无法加载，或者不支持此操作。请阅读 https://developers.facebook.com/docs/graph-api

这是我使用的代码。
