InputDatePicker class

Provides a date picker for a DateTime value.

The current value is displayed together with an icon. Tapping it opens a dialog box with a date picker. The picker can be fully customized.

To allow only dates in the past, set lastDate to or just add validators: [(v) => past( v ),].

To allow only dates in the future, set firstDate to or just add validators: [(v) => future( v ),].

TODO [X] year as an integer TextField TODO [X] Internationalize this input widget: day names, month names, tooltips, display format, first day of week

See InputField for all common parameters.
