YearPicker constructor
YearPicker({})
Creates a year picker.
The selectedDate and onChanged arguments must not be null. The lastDate must be after the firstDate.
Rarely used directly. Instead, typically used as part of the dialog shown by showDatePicker.

YearPicker({
Key? key,
required this.selectedDate,
required this.onChanged,
required this.firstDate,
required this.lastDate,
}) : assert(selectedDate != null),
assert(onChanged != null),
assert(!firstDate.isAfter(lastDate)),
super(key: key);
