我在GitHub和StackOverflow上尝试了几乎所有的解决方案，但都不起作用。在从基于英特尔的mac更改为M1 Max mac后，我的Flutter应用程序停止了编译，给出了这个奇怪的错误，没有任何进一步的细节。我正在附加XCode日志。我真的需要帮助。非常感谢。

我认为您使用的是较旧的flutter版本，该版本将WidgetBinding作为可为null的值，但在flutter 3+中，小部件绑定是不可为null。该功能发现已被解析为最新版本，可能仅适用于flutter 3+。
尝试降级支持旧版本的flutter 的功能发现包
尝试安装rosetta，这解决了我的问题。
sudo softwareupdate --install-rosetta --agree-to-license
