当我在iOS上测试它时，它工作正常，但当我尝试在XCode上存档时，它给予我以下错误：
未找到模块'audioplayer'
我使用audioplayers 0.13.5
正如你从我的pubspec文件中看到的，我有最新的flutter，一切正常，但我不知道为什么我会得到这个错误。
我也尝试了很多事情，如以下解决方案：

brew install cocoapods
pod setup

而且我还删除了iOS文件夹，重新安装。

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/mohammad.png
    - assets/new-word.png
    - assets/open-book.png
    - assets/icon/icon.jpeg
    - assets/elearning.png
    - assets/messenger.png
    - assets/icon/facebook.svg
    - assets/icon/instagram.svg
    - assets/icon/snapchat.svg
    - assets/icon/youtube.svg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: bahij
      fonts:
       - asset: assets/bahij.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
