board datetime picker

board_datetime_picker #
Picker to select date and time for Flutter.
It is both a calendar and a picker, offering a variety of options as a package.
On tablets, the calendar and picker can be displayed simultaneously for easy date/time selection. In other cases, the calendar and picker can be switched at the touch of a button for easy date/time selection.
Multiple selections are supported, and you can also select the start and end date and time in a single Picker display.
Features #

There are two types of Picker: a modal display and a builder display embedded in a widget.
