Added

• New attribute for HorizontalCalendar to set minSelection
• Validation for HorizontalCalendar parameters
• New Widget for example: CustomRangeSlider

Refactor

• Example
  • Using CustomRangeSlider you can select min and max selected date count. Once you want to set the new interval you have to tap on the "update" button and the widget is rebuilt with the new settings. If the setting can't be applied (range is too high for the available dates) a Snackbar is shown
  • General minor changes to optmize code indentation and remove some ambiguity (eg subtract(365) instead of add(-365) or DateTime.sunday instead of 7)

Hi, and thanks for this beautiful widget.

I wanna ask you if could you add an optional minSelectedDateCount parameter to avoid the no-selected-dates situations (this would be useful in such situations where a selected date is always required, for example retrieve a list of items that mathes that day).

Right now I am able to initialize the initialSelectedDates but without this optional setting i am able to remove it by tapping on the element.

  final isRemoved = selectedDates.remove(date);
  if (isRemoved && widget.onDateUnSelected != null) {
    widget.onDateUnSelected(date);
  }
}

Of course some validation should be added:

assert(maxSelectedDateCount >= minSelectedDateCount);
assert(initialSelectedDates.lenght >= minSelectedDateCount);

Hi 👋, First of all, thank you for your widget. It's exactly what I need. I'm just stuck on the local date. My settings language device are set to French and my Region too.

I use Locale myLocale = Localizations.localeOf(context); print(myLocale);to check the value. Everything look like ok, but the date format don't change.

Have you any ideas ?

In some layout situations the user could want to show the labels in uppercase. If no value for isLabelUppercase is given the label is shown in its original form

The package cannot be installed anymore because of intl version conflict. This error is reported on pub.dev too -> https://pub.dev/packages/horizontal_calendar_widget/score

Because horizontal_calendar_widget depends on flutter_localizations any from sdk which depends on intl 0.17.0, intl 0.17.0 is required. So, because horizontal_calendar_widget depends on intl ^0.16.1, version solving failed.

flutter_localizations already include intl dependency so is not necessary to add a direct dependency with version constraint

This is not working: initializeDateFormatting("sl").then((_) => runApp(MyApp()));

@milind-mevada-stl Can you tell what is the correct way to setup localization?
