pub get not finishing

[marcguilera]

Great job on this one! I'm trying out this server using the original example. I was able to push a library A without a problem but when calling pub get from library B which depends on A it simply never finishes the resolving packages stage. This is due to the following exception:

ERROR - 2018-08-09 23:53:30.287675

PS: Is there any plan to replicate all pub.dartlang.org functionality eventually? Including serving a website to browse packages, version, and documentation.

Can you please post the output of dart --version?

You've got to change the line that is a cast using List<Map> to a cast using List<dynamic>. It's line 33 of http_proxy_repository for the example code. At least that's what I did and it now appears to be fine.
