> I think it should be nonfree because we are not building from source. Afaik restricted is usually used for packages we can not distribute, is it this case?

Yeah, I didn't consider that, I guess this might better fit in in nonfree.

> Either way, building from source would be much better, we could build for multiple architectures, modify the source when needed and remove the nonfree restriction. This way it's equivalent to 2 commands - curl and tar xf

I agree, but this is the best we can do until somebody comes up with a template to build Flutter from source.
