kollavarsham_flutter

Flutter widgets for the Malayalam calendar (Kollavarsham), built on kollavarsham.

Malayalam months	Gregorian months with festival markers

• MalayalamMonthView: a month as a week grid, paging through Malayalam months or, with mode: CalendarMode.gregorian, Gregorian months in the style of a Kerala wall calendar. Each cell shows the other calendar's date (labelled where its month changes), and optionally the nakshatra and event markers. Swipe or use the arrows to change month, or tap the header to jump to any month and year.
• MalayalamMonthViewController: reads and changes the displayed month (jumpTo, next, previous).
• showMalayalamDatePicker: a date-picker dialog that returns a MalayalamDate.
• MalayalamDateText: a Text widget that formats a Malayalam date (today's by default).
• KollavarshamCalendarTheme: a ThemeExtension for the calendar's colours and cell shape.

Names appear in Malayalam script when the app's locale is ml and in transliteration otherwise. Pass script: to override this. Cells scale their text down to fit, so large accessibility text sizes don't overflow.

import 'package:kollavarsham_flutter/kollavarsham_flutter.dart';

MalayalamMonthView(
  mode: CalendarMode.gregorian,
  selectedDate: selected,
  showNakshatra: true,
  eventLoader: festivalEventLoader(), // marks Onam, Vishu, …
  onDateSelected: (date) => setState(() => selected = date),
);

final picked = await showMalayalamDatePicker(
  context: context,
  initialDate: MalayalamDate.today(),
  script: MalayalamScript.malayalam,
);

const MalayalamDateText(pattern: 'EEEE, d MMMM y');

Theming

ThemeData(
  extensions: const [
    KollavarshamCalendarTheme(
      holidayColor: Colors.deepOrange,
      markerColor: Colors.amber,
    ),
  ],
)

Values you leave out fall back to the app's ColorScheme, so the calendar follows light and dark themes automatically.

Your own events

eventLoader can return anything: festivals, birthdays or appointments. Use markerBuilder to draw them your own way.

MalayalamMonthView(
  eventLoader: (date) => myEvents[date] ?? const [],
  markerBuilder: (context, date, events) => Badge(label: Text('${events.length}')),
)

This package re-exports package:kollavarsham/kollavarsham.dart, so MalayalamDate, Nakshatra, the festival helpers and the rest are available from the one import.
