Feature Request: support for dart apps, not just Flutter

I need to do some video conversions in the server app I'm writing in Dart. I'd like to use your library to simplify things. Is there a reason your library is only usable in Flutter on iOS and Android? Would it be hard to add support for using your library in server apps?

My plan is to use Process.run() to run the required ffmpeg command (after making sure ffmpeg is installed on the server), but of course I would prefer to use a library like yours.
