0/10 points: 20% or more of the public API has dartdoc comments

2 out of 19 API elements (10.5 %) have documentation comments.

Providing good documentation for libraries, classes, functions, and other API elements improves code readability and helps developers find and use your API. Document at least 20% of the public API elements.

To highlight public API members missing documentation consider enabling the public_member_api_docs lint.

Some symbols that are missing documentation: date_range_picker_flutter, date_range_picker_flutter.CustomDateTimeRange, date_range_picker_flutter.CustomDateTimeRange.CustomDateTimeRange.new, date_range_picker_flutter.CustomDateTimeRange.end, date_range_picker_flutter.CustomDateTimeRange.start.
