Hello,

This is a port of the nixpkgs Dart compiler package [1]. I am interested
in it specifically because it is a transitive dependency of Hugo [2],
and I figured I other people might be interested in these packages, too.

The from-source build of Dart is quite the pain (nixpkgs seems to have
given up, but I do not know the story there). I looked around and while
I did not find a strict rule saying "source only", it does stand out by
relying on prebuilt artifacts. For my current needs it is good enough,
and I hope that in the future it could get a proper source build. I saw
there was an effort a few years ago, but it appears to have stopped
completely.
