How to make multiplatform flutter apk release or app bundle for playstore upload

Question

By multiplatform I mean arm64 and arm, using the default way of build a release apk it gives me an apk that works only on arm, but I can make an arm64 version by using the command

flutter build apk --release --target-platform --android-arm

The question is, how to make 1 apk for both platform or an app bundle that will work for play store?

Answer 1

I think is by using:

flutter build appbundle
