颤振构建apk

elamoh@DESKTOP-QUA3N6C MINGW64 /e/programes/Flutter_Req/sourceCode/app002
$ flutter build apk
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
        Learn more on:  https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

我也尝试过，但没有任何效果

$ flutter build appbundle --target-platform android-arm,android-arm64

在项目目录中创建了一个名为 build 的文件夹，但里面只有 app.dill 文件存在。没有 apk 没有 iOS 文件

请帮忙！！！谢谢

【解决方案1】：

您需要运行 flutter build apk 而不是 appbundle。应用程序包旨在发送到 Google Play，它将为您生成和优化 apk。完成后，apk 将位于 build\app\outputs\bundle\release\ 文件夹中。

最后它需要很长时间，但它已经完成了，谢谢

我可以在哪里找到 APK 文件！

【解决方案3】：

你的应用程序太大了，要减小它的大小，运行这个

flutter build appbundle --target-platform android-arm,android-arm64,android-x64

然后运行这个

flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi
