CupertinoDatePicker class Null safety

A date picker widget in iOS style.

There are several modes of the date picker listed in CupertinoDatePickerMode.

The class will display its children as consecutive columns. Its children order is based on internationalization, or the dateOrder property if specified.

Example of the picker in date mode:

  • US-English: | July | 13 | 2012 |
  • Vietnamese: | 13 | Th├íng 7 | 2012 |

Can be used with showCupertinoModalPopup to display the picker modally at the bottom of the screen.

Sizes itself to its parent and may not render correctly if not given the full screen width. Content texts are shown with CupertinoTextThemeData.dateTimePickerTextStyle.
