DatePicker class

A date picker widget.

The date picker widget allows users to select a date.

DatePicker requires an onChanged callback to be provided. This callback will be called when the user selects a date. The callback provides the selected year, month, and day.

The beginYear and endYear properties can be used to specify the range of years that the user can select. If these properties are not provided, the range of years will be from the current year to the current year plus 16.

The ascendingYear property can be used to specify whether the years should be displayed in ascending order. By default, the years are displayed in ascending order.

The initialDate property can be used to specify the initial date that the user should be displaying on initialization (ex. geting data from database). If this property is not provided, the initial will display the default value on first load.
