Suggestions

  • Fix lib/src/svd.dart.

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

    line: 14 col: 7
    Undefined class 'Numeric2DView'.

    • lib/src/qr.dart
  • Fix issues reported by dartanalyzer.

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

  • Package is pre-release.

    Pre-release versions should be used with caution, their API may change in breaking ways.

  • 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 grizzly_linalg.dart.
