NOTE: This is not a duplicate! My previous issue #64993 is closed because of wrongly marked as a duplicate. Thus I have no choice but to create it again :/

(Why not duplicate of #8230 : I want to bundle those 1MB photos only in Android. Thus, in the final .ipa file of iOS, there are no such photos taking space.)

Steps to Reproduce

Hi thanks for the wonderful Flutter! I have some images (1.1MB) that should only be used in Android, not iOS. Therefore, I want to remove those images from the IPA file in iOS. I have read the official doc, but it did not mention things like this :/

Expected results:

Give some options, such as (pubspec.yaml):

flutter:
  assets:
    android:
      - some_images_only_in_android/
    ios:
      - some_images_only_in_ios/
   all:
      - some_images_for_both/

Actual results: No such feature
