C:UsersiDesktopNew folderCovid-19-Flutter-UI-master>flutter build apk --release
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
