Perfect

I might be wrong, but java should not be involved here (I'm not
including java as an input).  I think it will be required when building
with the android sdk, but I still haven't tried running flutter yet, so
I've no idea.

However, during the "code polishing" I'll verify again that no binaries
are in the repo! (At first I tried using their tar.gz release, but they
included a full debian distribution (1.1Gb of gzipped data, 45Mb of
code)).

The repo is quite clean (with the downside that I have to specify all
compiler dart dependencies by hand.

I'll send a tentative patch series during the week, hopefully.

Thanks!
Nicolò
