If you want font awesome in native, you could use my Native Font Awesome widget. There is a demo to get you started easily. You need a custom build, does not work in the Make It Native app!
create an icon entity?
have svgs as string in the entity?
would this work?
Similar to naming icons for what they do (semantic icons), we are able to do something similar with snippets.
Its not the most elegant solution, but it works (for now).
