Hi - we intend to discontinue this package. It's no longer in use by the Dart team's tooling packages and has only limited use in the ecosystem (see https://pub.dev/packages?q=dependency%3Apub_cache).

Some possible recourse for people who are using this package:

• consume the output of dart pub cache list (that command didn't exist when this package was created)
• in-line the implementation; it's pretty minimal
• fork the package and re-publish (which may then imply some ongoing maintenance)

And as a heads up, newer Dart SDKs (2.19 and later) use pub.dev as the domain name in the cache dir path, instead of pub.dartlang.org.
