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: advanced_date_picker_plus_date_picker, advanced_date_picker_plus_date_picker.AdvancedDatePickerPlusDatePicker, advanced_date_picker_plus_date_picker.AdvancedDatePickerPlusDatePicker.AdvancedDatePickerPlusDatePicker.new, advanced_date_picker_plus_date_picker.AdvancedDatePickerPlusDatePicker.buttonPadding, advanced_date_picker_plus_date_picker.AdvancedDatePickerPlusDatePicker.cancelButtonStyle.
