【中文标题】无法构建flutter插件cloud_firestore，因为CloudFirestorePlugin.java使用未经检查或不安全的操作[flutter build apk]

【英文标题】：flutter plugin cloud_firestore could not be built because CloudFirestorePlugin.java uses unchecked or unsafe operations [flutter build apk]

【问题描述】：

我正在构建一个使用多个 firebase 依赖项的 Flutter 应用程序，但 cloud_firestore 依赖项在调试和构建应用程序时总是返回错误。这是构建日志

You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.

Building plugin cloud_firestore...
The plugin cloud_firestore could not be built due to the issue above.

使用的 pubspec.yaml firebase 依赖项：

firebase_core: ^0.4.4+3
cloud_firestore: ^0.13.4+2
firebase_auth: ^0.15.5+2 

任何有工作的 firebase 依赖项的人请在下面分享它们。

【问题讨论】：

似乎这是一个已知的行为：issuetracker.google.com/issues/110797725我如何重现这个？

@Mario 我不知道如何重现它，我只是使用了遇到它时的最新版本的 firebase 依赖项

【参考方案1】：

这似乎是一个暂时性问题，并且某些工具堆栈未正确同步。

我的建议是重新加载依赖项和所涉及的工具，因为在Issue Tracker 中，Android Studio 或 Gradle 之类的东西是通过以下方式恢复的：

删除文件夹：/.gradle 和 /.gradle 尝试使用本地 gradle 分发进行设置。

希望这很有用！

【参考方案2】：

要解决这个问题，请尝试两件事：

在项目/android/app/build.gradle

defaultConfig 
  ...
   multiDexEnabled true

在终端运行flutter pub upgrade

【讨论】：

MultiDexEnabled 设置为true 然后运行flutter clean 然后flutter pub upgrade 但我得到了同样的错误
