ios - 使用颤振编译到iOS时找不到错误是什么

Question

我已经尝试了大多数我能找到但无法修复错误的东西。我所有的包裹似乎都有问题。该代码在android上编译并运行。当我尝试在 Xcode 中编译代码时，它会在到达 firebase_auth 时停止。Flutter 版本是 1.22.6，我在设备上将开发目标设置为 10。我遇到的问题是一切，我可以向上滚动直到达到最大计数。

添加了更多错误，这与我的本地化有关。但是我添加了所有内容，就像它在为 iOS 添加本地化的操作指南中所说的那样。当我尝试添加不可为空的部分时，它会破坏我已经编写的代码，因为我没有为此编写代码。

它现在可以工作了，我所做的是我删除了颤振，重新下载了相同的版本。编译，现在它安装在设备上。
