I really wish you hadn't released this package. I may have to manually delete it
to prevent versioning issues in the future.

https://codereview.chromium.org/877433003/diff/1/pubspec.yaml
File pubspec.yaml (right):

https://codereview.chromium.org/877433003/diff/1/pubspec.yaml#newcode2
pubspec.yaml:2: version: 0.1.1
Why is this not a development version? If this CL exists to support development
versions of unittest, it should itself be a development version.

https://codereview.chromium.org/877433003/diff/1/pubspec.yaml#newcode9
pubspec.yaml:9: unittest: '>=0.11.0 <=0.12.0'
A "<=" constraint should never be used. What you're expressing here is that this
package will be compatible with unittest 0.12.0, which you don't know since that
doesn't exist yet, but it *won't* be compatible with 0.12.0+1 or any other
backwards-compatible unittest version, which just doesn't make sense.
