flutter build apk

$ 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

Solution

You need to run flutter build apk instead of appbundle. An app bundle is intended to be sent to Google Play, which will generate and optimize the apk for you. Once done, the apk will be in the build\app\outputs\bundle\release\ folder.
