Maintenance suggestions
The package description is too short. (20 points)
Add more detail to the description
field of pubspec.yaml
. Use 60 to 180 characters to describe the package, what it does, and its target use case.
Package is prev0.1 release. (10 points)
While nothing is inherently wrong with versions of 0.0.*
, it might mean that the author is still experimenting with the general direction of the API.
