当我通过USB调试模式将应用程序上载到设备时，我没有任何问题，该应用程序可以编译。另一方面，当我尝试生成.apk文件时，出现以下错误（见下文）。
错误的主要部分是在构建“√生成build \ app \ outputs \ repo”的“ Building plugin screen_state ...”时。东西
C:\flutter\flutter\flutter\bin\flutter.bat --no-color build 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
Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split
