thai_buddhist_date_pickers #

Screenshots & Demo #

Flutter calendar and pickers for Thai Buddhist (พ.ศ.) and Gregorian (ค.ศ.), distributed separately from the core thai_buddhist_date package.

• Month calendar header formats with BE/CE.
• Dialog pickers: single date, date-time (with preview), range, multi-date.
• Fullscreen single-date picker.
• Theming knobs for dialog shape/padding.

Install #

dependencies:
  thai_buddhist_date_pickers: ^0.1.6
  thai_buddhist_date: ^0.2.7

Usage #

import 'package:thai_buddhist_date_pickers/thai_buddhist_date_pickers.dart';
import 'package:thai_buddhist_date/thai_buddhist_date.dart' as tbd;

final picked = await showThaiDatePicker(context, era: tbd.Era.be, locale: 'th_TH');

Initialize Thai locale once if you want localized month/weekday names:

await tbd.ThaiDateService().initializeLocale('th_TH');

Picker variants #

Range picker #

final range = await showThaiDateRangePicker(
  context,
  era: tbd.Era.be,
  locale: 'th_TH',
);
// range?.start, range?.end

Multi-date picker #

final days = await showThaiMultiDatePicker(
  context,
  era: tbd.Era.be,
  locale: 'th_TH',
);
// days is Set<DateTime>

Fullscreen picker #

final d = await showThaiDatePickerFullscreen(
  context,
  initialDate: DateTime.now(),
  era: tbd.Era.be,
  locale: 'th_TH',
);
