【问题描述】：

Flutter Cloud Firestore 在我的 Flutter 应用程序上创建一个错误，当我在发布模式下的 APK 上执行它时，它只会使应用程序崩溃并关闭它。我有 AndroidX，当我从 flutter run --release 尝试应用程序并且我连接了我的设备时，一切正常。我有这个问题一周了，我还没有找到解决方法。

首先我认为这是谷歌地图插件的问题，但后来我意识到它也发生在我不使用它但我也使用 cloud_firestore 库的应用程序的其他部分。所以我认为这是有问题的

这是我执行flutter build apk时的控制台

You are building a fat APK that includes binaries for android-arm, android-arm64.
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
        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 --split-per-abi

【问题讨论】：

是的，但它是构建的。你能提供一个堆栈跟踪吗？
正如我告诉你的，在调试模式下一切正常，当我制作构建 apk 并安装它时，问题就出现了，它根本不起作用
你试过flutter run --release吗？
它与 Flutter run 配合得很好 --release 问题是当我创建一个 apk 文件时，当我从中执行应用程序时它会崩溃

【解决方案1】：

我认为以下几行指出了问题。

Resolving dependencies...                                           4.0s
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

弃用不是错误，而是警告。在这种情况下，它会警告您该功能最终将被删除。

这是一个已知的issue，根据这次对话，它已经是fixed
