Android 如何解决；运行Gradle时出错：“0”；飘飘然？

我正在尝试将firebase\u消息添加到项目中。我之前遇到了一些错误，我已经修复了这些错误。我最终遇到了这个错误，做了很多事情来解决这个问题，比如删除

.gradle

文件，但我无法解决此问题。请帮助我解决

  # To add assets to your application, add an assets section, like this:

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

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/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: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf

您的“以前的修复”现在可能正在执行这些错误。。。你为什么要删除gradle？您如何添加firebase_消息依赖项？我们需要更多信息，编辑并发布您的pubspec.yaml以及gradle文件（项目/应用级别）@fkvestak我已更新我的问题，请查看。
