【问题描述】：

您好，我终于完成了使用颤振开发我的应用程序，它取决于我开发时的 API 数据我使用我的手机运行它做得很好，但是当我需要使用 communed 输出 apk 时 flutter build apk 我可以显示，但是当使用来自 API 的数据登录应用程序时，我无法正常工作，但是当运行应用程序时，一切正常……有什么问题？？？

提示我何时构建 apk

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
