onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
void onInit() {
  pageController = PageController(initialPage: initialPageNumber);

  displayedRange.value = calculateDateRange(initialPageNumber);

  selectedYear.value = selectedDate != null
      ? PickerPlusDateUtilsX.yearOnly(selectedDate!)
      : null;

  super.onInit();
}
