Date Selection #

CleanCalendar( enableDenseViewForDates: true, enableDenseSplashForDates: true, datesForStreaks: [ DateTime(2022, 8, 5), DateTime(2022, 8, 6), ... ], // Enabling selecting single or multiple dates. Defaults to disable selection. dateSelectionMode: DatePickerSelectionMode.singleOrMultiple, // Listening to selected dates. onSelectedDates: (List<DateTime> value) { // If selected date picked again then removing it from selected dates. if (selectedDates.contains(value.first)) { selectedDates.remove(value.first); } else { // If unselected date picked then adding it to selected dates. selectedDates.add(value.first); } // setState to update the calendar with new selected dates. setState(() {}); }, // Providing calendar the dates to select in ui. selectedDates: selectedDates, // Customizing selected date. selectedDatesProperties: DatesProperties( datesDecoration: DatesDecoration( datesBorderRadius: 1000, ), ),)copied to clipboard

Single date selection
For single date selection modify the above example code onSelectedDates logic to store only single latest date as selected.

Range, multiple ranges (coming soon)

Changing calendar view type #
Currently mothly and weekly views are added. You can change them as shown below:
CleanCalendar(
// Setting DatePickerCalendarView.weekView for weekly view
datePickerCalendarView: DatePickerCalendarView.weekView,
)
copied to clipboard
Note: datePickerCalendarView defaults to DatePickerCalendarView.monthView.
Changing calendar start weekday #
You can change the claendar start weekday as shown below:
CleanCalendar(
// Setting start weekday
startWeekday: WeekDay.monday,
)
copied to clipboard
Note: startWeekday defaults to WeekDay.sunday.
Changing weekday and month symbols #
You can change the claendar months and weekdays symbols as shown below:
CleanCalendar(
// Setting custom weekday symbols
weekdaysSymbol: const Weekdays(sunday: "s", monday: "m", tuesday: "t", wednesday: "w", thursday: "t", friday: "f", saturday: "s"),
// Setting custom month symbols
monthsSymbol: const Months(january: "Jan", february: "Feb", march: "Mar", april: "Apr", may: "May", june: "Jun", july: "Jul", august: "Aug", september: "Sep", october: "Oct", november: "Nov", december: "Dec"),
)
copied to clipboard
Note: weekdaysSymbol defaults to Mo, Tu, We, Th, Fr, Sa, Su from monday to sunday and monthsSymbol defaults to January, February, March, April, May, June, July, August, September, October, November, December.
Accessing selected dates #
To access selected dates use the onSelectedDates callback but keep in mind that this callback always provides a list of dates as shown below:
CleanCalendar(
...
onSelectedDates: (List<DateTime> selectedDates) {
// Called every time dates are selected or deselected.
print(selectedDates);
},
)
copied to clipboard
Note: Even for single selection mode it provides a list with just one date and for multiple selection it provides a list with multiple dates.
Providing pre-selected dates #
You can provide pre-selected dates by providing a list of dates to selectedDates as shown below:
CleanCalendar(
...
selectedDates: [
DateTime(2022, 8, 6),
DateTime(2022, 8, 9),
DateTime(2022, 8, 11),
],
)
copied to clipboard
Note: Even with selection mode set to single or disable it will still show the provided pre-selected dates as selected. And I think is the correct behavious as sometimes we might want to show selected dates while also preventing users from interacting with them.
Providing start and end dates #
You can provide start and end dates for calendar view as shown below:
CleanCalendar(
...
// Setting start date of calendar.
startDateOfCalendar: DateTime(2022,6,5),

// Setting end date of calendar.
endDateOfCalendar: DateTime(2022,10,15),
)
copied to clipboard
Note: startDateOfCalendar defaults to DateTime.utc(0000, 1, 1) and endDateOfCalendar defaults to DateTime.utc(9999, 1, 1).
Providing initial month view for calendar #
You can provide initial month view for calendar by providing date of that month as shown below:
CleanCalendar(
...
// Setting initial month view of calendar.
initialViewMonthDateTime: DateTime(2022,9,5),
)
copied to clipboard
Note: initialViewMonthDateTime defaults to current date and if current is not between startDateOfCalendar and endDateOfCalendar then defaults to start date..
Providing current date for calendar #
You can provide current date for calendar as shown below:
CleanCalendar(
...
// Setting current date of calendar.
currentDateOfCalendar: DateTime(2022,9,5),
)
copied to clipboard
Note: currentDateOfCalendar defaults to DateTime.now().
Listening for calendar view week or month change #
You can listen and get the current calendar view date on calendar view change. Useful in case you want to change your ui acording to the dates visible to user.
CleanCalendar(
...
onCalendarViewDate: (DateTime calendarViewDate) {
// Called every time view is changed like scrolled etc.
print(calendarViewDate);
},
)
copied to clipboard
Note: For now onCalendarViewDate will only provide the view starting date. Later I may can add an option to get all dates of current view depending on users request. Also, onCalendarViewDate is called only on change of view like scroll, etc and will not be called on the creation of calendar as at thst time we already know the date.
Additional information #
Support is surely planned for these:

Complete documentation.

Option to disable user interactions on whole view, past dates, and dates after-before end-start date. (🐇)

More customization and premade templates for calendar. (🐢)

More calendar view types. (🐢)

Date selection options such as range, and multiple range selections. (🐢)

A calendar option for choosing a view by year, month, or day. (🐢)

Support for dates to be displayed in events style. (🐢)

Dry mode, which optimizes performance for low-end devices by removing or substituting heavy animations and widgets. (🐢)

And, if I'm forgetting something crucial/important/necessary then please let me know.
