We analyzed this package on May 8, 2019, and provided a score, details, and suggestions below. Analysis was completed with status completed using:

• Dart: 2.3.0
• pana: 0.12.15

#### Platforms

Detected platforms: Flutter, web, other

No platform restriction found in primary library `package:dart_math/dart_math.dart`.

#### Health issues and suggestions

Document public APIs. (-0.33 points)

43 out of 44 API elements have no dartdoc comment.Providing good documentation for libraries, classes, functions, and other API elements improves code readability and helps developers find and use your API.

Format `lib/matrix.dart`.

Run `dartfmt` to format `lib/matrix.dart`.

#### 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 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.
