I tested them. Pub works. Goodbye, world!

How does it work?

Yeah, it's mostly a hack.

We create a binary (using Go) that contains everything you need tar'd and chopped into chunks. Each chunk is embedded as a literal byte array in Go source. These arrays are rejoined and unpacked into /tmp at runtime by a bootstrapper which just executes dart bin/main.dart.

Performance

Not entirely terrible. The whole build takes around 5 seconds on this crappy laptop, and the binaries seem to start pretty fast.
