Use constrained dependencies. (-20 points)

The pubspec.yaml contains 1 dependency without version constraints. Specify version ranges for the following dependencies: protobuf.

Homepage URL isn't helpful. (-10 points)

Update the homepage field from pubspec.yaml: link to a website about the package or use the source repository URL.

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 pre-v0.1 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.
