Suggestions

  • Fix lib/compass.dart.

    Strong-mode analysis of lib/compass.dart failed with the following error:

    line: 4 col: 8
    Target of URI doesn't exist: 'dart:json'.

  • Fix lib/src/geom/vector.dart.

    Strong-mode analysis of lib/src/geom/vector.dart failed with the following error:

    line: 31 col: 3
    Invalid override. The type of 'Vector.==' ('(Vector) → bool') isn't a subtype of 'Object.==' ('(dynamic) → bool').

  • Fix further 1 Dart files.

    Similar analysis of the following files failed:

    • lib/src/renderer/renderer.dart
  • Fix platform conflicts.

    Make sure none of the libraries use mutually exclusive dependendencies.

  • Maintain CHANGELOG.md.

    Changelog entries help clients to follow the progress in your code.

  • Fix issues reported by dartanalyzer.

    dartanalyzer reported 3 error(s) and 0 warning(s).

  • Use constrained dependencies.

    The pubspec.yaml contains 3 dependencies without version constraints. Specify version ranges for the following dependencies: browser, stats, vector_math.

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    None of the files in your example/ directory matches a known example patterns. Common file name patterns include: main.dart, example.dart or you could also use compass.dart.
