Issue in setting correct dates to be displayed.

[Aryan2892]

I want to set the the date to be displayed as 1st january 13 years from now. How can I do it? even if i initialize it to DateTime(2013,1,1) this widget still shows 2nd FEB 2024. Can you please tell me what is wrong or how can I fix it?

final DateTime currentDate = DateTime.now();
final DateTime initialDate = DateTime(currentDate.year - 13, 1, 1); 

ScrollWheelDatePicker(
    initialDate: initialDate,
    startDate: initialDate,
    lastDate: currentDate,
    theme: CurveDatePickerTheme(
      wheelPickerHeight: 200.0,
      overlay: ScrollWheelDatePickerOverlay.highlight,
      itemTextStyle: GoogleFonts.urbanist(
        color: Theme.of(context).colorScheme.secondary,
        fontSize: 30,
        fontWeight: FontWeight.w800,
      ),
      monthFormat: MonthFormat.threeLetters,
      overlayColor: Theme.of(context).colorScheme.primary,
      overAndUnderCenterOpacity: 0.2,
    ),
    onSelectedItemChanged: (value) {
      Logger().d('Selected date: $value');
      setState(() {
        _selectedDate = value;
      });
    },
),

For 13 years ago:

final initialDate = DateTime.now().subtract(const Duration(days: 13* 365))

For 13 years ago and 1st january:

final daysCount = now.difference(january1st).inDays;
DateTime.now().subtract(const Duration(days: (13* 365) + daysCount));

DateTime.now().subtract(const Duration(days: (13* 365) + daysCount));

Hi, in final dayCount I am not finding how to implement now.difference is undefined for me. I initialized it like this accorinfg to my understanding of what now meant final DateTime now = DateTime.now(); But january1st is still undefined.

The issue that I am facing is that I when I scroll past the start date it gives this error: Last date must be after the initial date or DateTime.now(). 'package:scroll_wheel_date_picker/src/date_controller.dart': Failed assertion: line 50 pos 14: 'DateTime.now().isBefore(lastDate)'

    final DateTime currentDate = DateTime.now();
    final DateTime firstDate = DateTime(2011, 1, 1);
ScrollWheelDatePicker(
                initialDate: firstDate,
                startDate: firstDate,
                lastDate: currentDate,
                theme: CurveDatePickerTheme(
                  wheelPickerHeight: 200.0,
                  overlay: ScrollWheelDatePickerOverlay.highlight,
                  itemTextStyle: GoogleFonts.urbanist(
                    color: Theme.of(context).colorScheme.secondary,

                    fontWeight: FontWeight.w800,

                  monthFormat: MonthFormat.threeLetters,

                ),
                onSelectedItemChanged: (value) {
                  WidgetsBinding.instance.addPostFrameCallback((_) {
                    setState(() {
                      _selectedDate = value;
                    });
                  });
                },
              ),

Another error I am facing is that after screen loads the widget and I scroll upwards as in to go to previous months. It says widget cannot be marked as needing to build because the framework ' 'is already in the process of building widgets. A widget can be marked as ' 'needing to be built during the build phase only if one of its ancestors ' 'is currently building. This exception is allowed because the framework ' 'builds parent widgets before children, which means a dirty descendant ' 'will always be built. Otherwise, the framework might not visit this ' 'widget during this build phase.' specificaly when I scroll months, date and year are fine when I scroll but when I scroll months it shows error. Also I have set it to 3 letters but its showing entire month name.

@Aryan2892 Have you check this 2dd7e507c0931005c2359400c129e2f4d8093d08? If not, kindly clone and check if the issue has been resolved or not. I believe the assert error was fixed in that commit. Also open another issue if you found another one instead of populating it inside another issue, thanks!
