从几天前开始，我就失去了为iOS构建Flutter应用程序的能力。我将iPad更新为11.4，这迫使我将xCode更新为9.4，而且我认为还添加了Flutter的新版本。我以无限的智慧更新了所有内容，现在再也无法测试我的项目了。
随着截止日期的临近，我正在寻找有关如何再次搬家的建议。我对Apple产品不那么熟悉，所以还真的不了解我对xCode等的了解。
这是一个全新的“ FLUTTER CREATE测试项目”项目，没有任何更改。

我猜这个问题是由中断 cocoapods 安装引起的。这是修复：
pod install在ios目录下运行。应生成 Flutter.framework，包括Headers/Flutter.h文件虽然切换到不同的 Flutter 可能会奏效，但它并不能真正解决缓存损坏的问题。请记住，Flutter 的 master 和 beta 分支不适合生产版本。

cd ios
pod install
如果它不起作用那么
pod update
flutter clean
flutter run

我整天都在寻找答案，最后找到了可行的修复程序，请在您的终端中运行该修复程序：
颤振通道主控
扑扑干净
扑动
我认为这只是一个扑朔迷离的错误/不兼容，尚未出现在主要渠道上。
当我尝试在我的 flutter 项目中添加共享按钮时遇到了这个问题。
