Add Linux support

[guyluz11]

Description

I would like to use it on Linux as well, currently the platform is missing from the list on pub.dev

Can we add Linux support?, also what missing if not?.

Scenario

Use the plugin in my own application via Flutter dependency

Platform

None

That would be great! It would involve implementing the whole Linux layer though. I remember thinking it should probably be based on Avahi. I definitely won't be able to do this in the near future, but I'll keep this issue as enhancement.
