Cannot create a FlutterEngine instance in debug mode without Flutter tooling or Xcode.

To launch in debug mode in iOS 14+, run flutter run from Flutter tools, run from an IDE with a Flutter IDE plugin or run the iOS project from Xcode.
Alternatively profile and release mode apps can be launched from the home screen.

在没有 Flutter 工具或 Xcode 的情况下，无法在调试模式下创建 FlutterEngine 实例。

要在 iOS 14+ 中以调试模式启动，请从 Flutter 工具运行 flutter run，从带有 Flutter IDE 插件的 IDE 运行或从 Xcode 运行 iOS 项目。
或者，可以从主屏幕启动配置文件和发布模式应用程序。
