I have a lot of packages in the /Users/xxx/.pub-cache/hosted/pub.dev/, but the getPackageRefs and getAllPackageVersions return empty collection.

  var cache = PubCache();
  var refs = cache.getPackageRefs();
  var versions = cache.getAllPackageVersions("<the package name i.e. libgit2dart>");

Versions:

• pub-cache: 0.3.1
• MacOS: 12.6.2

I tried chmod -R 777 ~/.pub-cache just in case it's a permission issue, but still didn't work.
