在这种情况下，在 flutter 中构建 .apk 文件有什么问题？

Question

我最近一直在用 flutter 写一个 app 命名为 app002，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

Flutter Doctor

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

[√] Android Studio (version 3.5)
[√] VS Code, 64-bit edition (version 1.40.2)

这个命令耗时太多，没有执行

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

我也试过这个，但什么都没有

$ 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**

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 个文件

求助！！！谢谢

我在哪里可以找到 APK 文件！

Answer 2

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。

Answer 3

您的应用程序太大，要缩小尺寸运行这个

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
