Introduction to Hijri Date Range Picker in Flutter

The Islamic or Hijri calendar is a lunar calendar consisting of 12 months in a year of 354 or 355 days. We have added the Hijri date picker in our 2020 Volume 4 release to display the Islamic calendar.

This widget has all the Gregorian calendar functionalities like minimum and maximum dates, the first day of the week, different selection modes, RTL, and customization for special dates.

Multiple picker views

Display month, year, and decade views that allow users to easily select and navigate between built-in views using UI and programmatically.

Date selection

You can select single, multiple, and a range of dates. The widget also supports programmatic selection.

Programmatic date selection

Select dates programmatically in the Hijri date-range picker using the selectedDate, selectedDates, selectedRange, and selectedRanges properties in HijriDatePickerController. You can also use the corresponding selectionMode to select the dates programmatically.

class MyAppState extends State<MyApp> {
  HijriDatePickerController _controller;

  @override
  void initState() {
    _controller = HijriDatePickerController();
    _controller.view = HijriDatePickerView.month;
    _controller.selectedRanges = <HijriDateRange>[
      HijriDateRange(HijriDateTime.now().add(Duration(days: 4)),
          HijriDateTime.now().add(Duration(days: 9))),
      HijriDateRange(HijriDateTime.now().add(Duration(days: 11)),
          HijriDateTime.now().add(Duration(days: 16)))
    ];
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: SfHijriDateRangePicker(
        selectionMode: DateRangePickerSelectionMode.multiRange,
        controller: _controller,
      )),
    );
  }
}

First day of week

The Date Range Picker widget will be rendered with Sunday as the first day of the week. You can customize it to any day using the firstDayOfWeek property. The following code example illustrates this.

@override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: SfHijriDateRangePicker(
        view: HijriDatePickerView.month,
        monthViewSettings: HijriDatePickerMonthViewSettings(firstDayOfWeek: 1),
      )),
    );
  }

Appearance customization
