DefaultValue not working

[Azzen-V]

Hey, I really love your date picker but the default value is not working. There is no date selected even if I specified a default value. This is my code:
CoolDatepicker( onSelected: widget.onSelected, maxYear: 2222, minYear: 2019, calendarSize: 350, firstWeekDay: 1, format: 'dd.mm.yyyy', defaultValue: [DateTime.now()], monthLabelList: const [ 'Januar', 'Februar', 'März', 'April', 'Mai', 'Juni', 'Juli', 'August', 'September', 'Oktober', 'November', 'Dezember', ], isYearMonthDropdownReverse: true, isResultLabel: true, resultWidth: 300, resultBD: BoxDecoration( color: Theme.of(context).colorScheme.background, border: Border( bottom: BorderSide( color: Theme.of(context).colorScheme.secondary, ), ), ), resultTS: TextStyle( fontSize: 20, color: Theme.of(context).colorScheme.onSecondary, ), placeholder: s.lblDate, headerColor: Theme.of(context).colorScheme.secondary, arrowIconAreaColor: Theme.of(context).colorScheme.secondary, selectedCircleColor: Theme.of(context).colorScheme.secondary, selectedBetweenAreaColor: Theme.of(context).colorScheme.secondary, cancelFontColor: Theme.of(context).colorScheme.secondary, cancelBtnLabel: 'Abbrechen', okButtonColor: LinearGradient(colors: [ Theme.of(context).colorScheme.secondary, Theme.of(context).colorScheme.secondary, ]), bottomSelectedBorderColor: Theme.of(context).colorScheme.secondary, isDark: true, )
Did I do something wrong?

CoolDatepicker(
onSelected: (_) {},
maxYear: 2222,
minYear: 2019,
calendarSize: 350,
firstWeekDay: 1,
format: 'dd.mm.yyyy',
placeholder: 'dd.mm.yyyy',
defaultValue: [DateTime.now()],
monthLabelList: const [
'Januar',
'Februar',
'März',
'April',
'Mai',
'Juni',
'Juli',
'August',
'September',
'Oktober',
'November',
'Dezember',
],
isYearMonthDropdownReverse: true,
isResultLabel: true,
resultWidth: 300,
resultBD: BoxDecoration(
color: Theme.of(context).colorScheme.background,
border: Border(
bottom: BorderSide(
color: Theme.of(context).colorScheme.secondary,
),
),
),
resultTS: TextStyle(
fontSize: 20,
color: Theme.of(context).colorScheme.onSecondary,
),
headerColor: Theme.of(context).colorScheme.secondary,
arrowIconAreaColor: Theme.of(context).colorScheme.secondary,
selectedCircleColor: Theme.of(context).colorScheme.secondary,
selectedBetweenAreaColor:
Theme.of(context).colorScheme.secondary,
cancelFontColor: Theme.of(context).colorScheme.secondary,
cancelBtnLabel: 'Abbrechen',
okButtonColor: LinearGradient(colors: [
Theme.of(context).colorScheme.secondary,
Theme.of(context).colorScheme.secondary,
]),
bottomSelectedBorderColor:
Theme.of(context).colorScheme.secondary,
isDark: true,
)

It works well for me, I just modified placeholder and onSelected options in your code.
There is no any errors or specific problems?
