datepicker_studio 1.0.0

A themeable date picker toolkit for Flutter — range, single, birthday, and date-time modes across a bottom sheet, dialog, inline calendar, and form field.

1.0.0

Initial release.

Entry points — four presentations over one calendar engine: showDateRangeSheet (modal bottom sheet), showDateRangeDialog (centred dialog), DateRangePickerView (inline), and DateRangeField (a tappable form field).

Modes — range, single, birthday (year → month → day drill-down with an age summary and maxDate defaulting to today), and dateTime (a span carrying a time of day on each endpoint, with minuteInterval and use24HourFormat).

Selection rules — minDate/maxDate bounds, a selectableDayPredicate for per-day filtering, and minRangeLength/maxRangeLength limits enforced while selecting rather than rejected afterwards.

Presets — nine built-in shortcuts plus fully custom ones, each clamped to the configured bounds. Individual default chips can be hidden via showTodayPreset, showLast7DaysPreset, and their siblings.

Theming — twelve colour slots, seven radii including buttonRadius, chipRadius, and dayRadius, plus six text styles. Every unset field resolves from the ambient ThemeData, so light and dark work without configuration.

Localisation — configurable first day of week, locale, date formats, and all UI strings via DateRangePickerLabels.

Also — horizontal month paging with swipe support, a tappable year grid, multi-month layouts that collapse on narrow screens, hover range preview on desktop and web, today highlighting, and semantics labels on day cells.

No dependency on flutter_screenutil or any state-management package; intl only.
