我最近发布了一个更新（版本xx（xidox. x））在播放商店的Myapp上。我收到一条错误信息（无法安装Myapp）请检查附加的屏幕截图。当用户尝试更新应用程序，但是，初始安装（如果用户卸载现有应用并重新安装应用）运行正常，在我的应用中，我写了一个程序，当我们在Play商店有更高版本可用时通知我们的用户，这个功能会将用户重定向到应用商店安装更新，工作正常，在这个版本发布之前，用户能够安装更新。我已经尝试了建议的选项，如清除Play商店的缓存和允许更新所有网络上的应用程序等。希望您提供指导以解决此问题。

description: A new Flutter application.

# 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.

flutter:

  # 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/logo_new.png
    - assets/
    #    - assets/logo_xtra_trust.png
    - assets/XTRANET_CPS_Ver4.0.0_signed.pdf
    - assets/subscriber_agreement.pdf
    - assets/subscriber_agreement_hindi.pdf

  # 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: Poppins
      fonts:
        - asset: fonts/poppins_regular.ttf
