After #146263 and #146264 have landed, we could consider sending existing flutter data assets to link hooks:

# pubspec.yaml of my_app
...
flutter:
...
  assets:
    - path: assets/translations.json
      link: messages # invokes package:messages' hook/link.dart to shrink  assets/translations.json

Alternatively, we could tell users that if they would like their assets to be tree shaken by a link hook, they must use a build hook to report them.

Somewhat similar behavior to

• ☂️ Implement pluggable transformation (via packages) of assets at build time #143348

Related umbrella issues:

• ☂️ Build hooks & Code assets #129757
• [native_assets_cli] data assets dart-lang/native#154
