我正在尝试将Firebase集成到我现有的Flutter应用程序中。在集成之前，我已经将我的项目从Android Studio迁移到了AndroidX。我已经完成了官方指南中提到的将Firebase集成到Flutter中的步骤。当我运行应用程序时，它会给我错误：

• 运行Gradle时出错：ProcessException：进程“E：\My Projects\MyProject\android\gradlew.bat”异常退出：

失败：生成失败，出现异常。

• 其中：构建文件'E：\My Projects\MyProject\android\app\build.gradle'行：24
• 出了什么问题：评估项目“：app”时出现问题。

• Try：使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。使用--scan运行以获得完整的见解。
• 在https://help.gradle.org获取更多帮助

BUILD在8 s命令中失败：E：\My Projects\MyProject\android\gradlew.bat app：properties
请在android/文件夹中查看Gradle项目设置。
我搜索了这个错误，找到了一些指示从com.google.gms:google-services:4.3.2切换到com.google.gms:google-services:4.2.0的答案。这样做，得到了这个错误：
registerResGeneratingTask已弃用，use registerGeneratedResFolders（FileCollection）registerResGeneratingTask已弃用，use registerGeneratedResFolders（FileCollection）registerResGeneratingTask已弃用，use registerGeneratedResFolders（FileCollection）Gradle任务装配调试失败，退出代码为% 1
搜索了一下，发现com.google.gms:google-services:4.3.0修复了这个问题。所以我在build.gradle中使用了它，这是我得到的：

• 运行Gradle时出错：ProcessException：进程“E：\My Projects\MyProject\android\gradlew.bat”异常退出：

失败：生成失败，出现异常。

• 其中：构建文件'E：\My Projects\MyProject\android\app\build.gradle'行：24

请在android/文件夹中查看Gradle项目设置。
似乎没有什么对我有用。请在下面找到gradle文件的内容。

description: A new Flutter project.

# 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.

  # An image asset can refer to one or more resolution-specific "variants", see

  # For details regarding adding assets from package dependencies, see

  # 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: Muli
      fonts:
        - asset: fonts/Muli-ExtraLight.ttf
