我对 Flutter & Dart 还很陌生。我可以尝试什么？
我有类似的错误，经过多次尝试，我以这种方式解决了：
- 更新 MacOS
- 更新Xcode 和命令行工具
- 运行
flutter pub upgrade, flutter pub get 在项目文件夹
- 删除项目ios文件夹中的podfile.lock
- 运行
cd ios, pod repo update, pod install 项目文件夹

我尝试删除 *.g.dart 和 运行 我能找到的所有类似问题的解决方案，但没有任何效果。这一切似乎都是在我将以下内容添加到我的 info.plist 之后发生的，但不确定这是否相关。

当我在 vs 代码的输出 运行 中执行 flutter 运行 时也得到以下信息 window 但不确定是否相关：

我对 Flutter & Dart 还很陌生。我可以尝试什么？
我有类似的错误，经过多次尝试，我以这种方式解决了：
- 更新 MacOS
- 更新Xcode 和命令行工具
- 运行
flutter pub upgrade,flutter pub get在项目文件夹 - 删除项目ios文件夹中的podfile.lock
- 运行
cd ios,pod repo update,pod install项目文件夹
