Suggestions

  • Maintain CHANGELOG.md.

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

  • 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.

  • Fix analysis and formatting issues.

    Analysis or formatting checks reported 4 hints.

    Strong-mode analysis of lib/src/base_chart.dart gave the following hint:
