在这种情况下，如何在颤动的.apk文件中构建问题？

Question

我最近一直在写一个名为app002的应用程序，但是我遇到了一些问题，我需要知道如何解决它们，我使用GitBash作为终端机

Flutter Doctor

 lamoh@DESKTOP-QUA3N6C MINGW64 /e/programes/Flutter_Req/sourceCode
$ flutter doctor

这名突击队员花了太多时间并且没有受到谴责

flutter build 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

我也尝试这个，但是什么也没有

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

    lamoh@DESKTOP-QUA3N6C MINGW64 /e/programes/Flutter_Req/sourceCode/app002
**$ flutter build appbundle --target-platform android-arm,android-arm64**
Initializing gradle...                                              2,3s

在项目目录中创建了一个名为build的文件夹，但在其中仅存在app.dill文件。没有apk没有iOs文件

请帮助！！！ 感谢

Built build\app\outputs\bundle\release\app.aab (10.5MB).

我可以在其中找到APK文件的地方！

Answer 2

您需要运行flutter build apk而不是appbundle。打算将应用程序捆绑发送到Google Play，后者会为您生成和优化apk。完成后，apk将位于build\app\outputs\bundle\release\文件夹中。
