I would prefer that we only use one path library in the test scripts. Either we
use the one in dart:io or the one in pkg. We are going to evaluate where to got
with path this quarter to eliminate one of them. Can we stick to the one in
dart:io for now?

It seems like what you are using is relativeTo which is also in the dart:io
library:
