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

Flutter 1.5.4-hotfix.2 appbundle currently targets android-arm which builds only 32bit native code (flutter build appbundle -h). To change this run flutter build appbundle --target-platform=android-arm64 to change the default target.
