我正在使用Flutter，并在iOS模拟器的帮助下构建一个应用程序。
当我运行flutter doctor时，我得到以下错误：

flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.7.11, on macOS 13.3.1 22E261 darwin-arm64, locale en-DE)

    ✗ Unable to locate Android SDK.
      Install Android Studio from: https://developer.android.com/studio/index.html
      On first launch it will assist you in installing the Android SDK components.
      (or visit https://flutter.dev/docs/get-started/install/macos#android-setup for detailed instructions).
      If the Android SDK has been installed to a custom location, please use
      `flutter config --android-sdk` to update to that location.

我不能再构建应用程序了。我以前从未遇到过类似的问题。
我使用以下版本：

flutter --version
Flutter 3.7.11 • channel stable • https://github.com/flutter/flutter.git
Framework • revision f72efea43c (24 hours ago) • 2023-04-11 11:57:21 -0700
Engine • revision 1a65d409c7
Tools • Dart 2.19.6 • DevTools 2.20.1

xcodebuild -version
Xcode 14.3
Build version 14E222b

我已经执行了sudo xcodebuild -runFirstLaunch，它什么也没做。
flutter clean也没有帮助。
我重新安装了Xcode和Flutter，但它没有帮助。
