CupertinoTimerPicker class

A countdown timer picker in iOS style.

This picker shows a countdown duration with hour, minute and second spinners. The duration is bound between 0 and 23 hours 59 minutes 59 seconds.

There are several modes of the timer picker listed in CupertinoTimerPickerMode.

The picker has a fixed size of 320 x 216, in logical pixels, with the exception of CupertinoTimerPickerMode.hms, which is 330 x 216. If the parent widget provides more space than it needs, the picker will position itself according to its alignment property.
