Exception during upgrade #1846
Description
With a bleeding edge build (18cc35f78c6239cce39d97c86a1e1214f912db38), on my Mac, I ran pub upgrade in the 'linter' package. It resulted in an exception and requested that I create an issue with trace output. The trace output was:
$ pub --trace upgrade
Resolving dependencies...
The method 'read' was called on null.
Receiver: null
Tried calling: read(Instance of '_SimpleUri', headers: Instance of '_ImmutableMap')
