Figured it out. You only fixed this bug in master and not in the release on heroku's buildpack registry so when just add "ee/heroku-buildpack-flutter-light" then adds from registry and doesn't work but if add with full github url then works fine. You can close this if you want but i would recommend leaving it up until it is either fixed on the registry or you change the README to use the full github url instead of the one on heroku's buildpack
