Could not find an option named “split-per-abi”

 

In your <app dir>/android/app/build.gradle add a splits section as described here: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

A basic configuration would be to add this to your build.gradle

android {
  ...
  splits {

    // Configures multiple APKs based on ABI.
    abi {

      // Enables building multiple APKs per ABI.
      enable true

      // By default all ABIs are included, so use reset() and include to specify that we only
      // want APKs for x86 and x86_64.

      // Resets the list of ABIs that Gradle should create APKs for to none.
      reset()

      // Specifies a list of ABIs that Gradle should create APKs for.
      include "x86", "x86_64", "armeabi", "armeabi-v7a", "arm64-v8a"

      // Specifies that we do not want to also generate a universal APK that includes all ABIs.
      universalApk false
    }
  }
}

Then just run the command as the documentation says:

flutter build apk --split-per-abi

Here is the list of supported ABIs: https://developer.android.com/ndk/guides/abis.html#sa

With the config above you should get all supported ABIs
