How to build app compliant with Google Play 64-bit requirement?

Question

After I upload the APK to play store I got the following warning. What changes should I make to release an APK build with flutter SDK to meet the 64-bit requirement?

Answer 1

What worked for me was

flutter build appbundle --release 

Upload the appbundle file

Then increase the version and build number in the pubspec.yml file and run

flutter build appbundle --release --target-platform=android-arm64

Upload also this new appbundle.

Then the play store accepted my release
