Transform's input file does not exist: C:\Users\user\AppData\Local\Pub\Cache\hosted\pub.dev\get_mac_address-0.0.2\android\Users\vickyleu\Develop\flutter\bin\cache\artifacts\engine\android-arm64-release\flutter.jar

This file does not exist in the library. Confirmed this, confirmed setting lintOptions to false does not resole the issue per git/issues/58247

Its worth noting that if you're chasing this plugin for MAC address in android 11+ you wont get it. I recommend following Goggles best practices for unique identifiers based on use case.
