datepicker_studio

A themeable date & time picker toolkit for Flutter — range, single, birthday, date-time, week & multi-date, as a sheet, dialog, inline calendar, field, or iOS modal.

---

Install

dependencies:
  datepicker_studio: ^1.1.0

import 'package:datepicker_studio/datepicker_studio.dart';

final range = await DateRangePickerSheet(context);   // null if cancelled
print('${range?.start} → ${range?.end} · ${range?.days} days');

Presets, month swiping, a year picker, and your app's colours — out of the box.

Show it

DateRangePickerSheet(context);      // bottom sheet (phones)
DateRangePickerPopup(context);      // centred dialog (tablet / desktop / web)
DateRangePickerAdaptive(context);   // sheet or dialog, by screen width
DateRangePickerCupertino(context);  // iOS-style modal with Cancel/Done

DateRangePickerView(showActions: false, onChanged: (r) => …);  // inline widget
DateRangeField(value: _range, onChanged: (r) => …);            // tap-to-open field
DateRangeFormField(validator: (r) => r == null ? 'Required' : null);  // in a Form

Both fields are fully styleable — pass any decoration, plus borderRadius and textStyle:

DateRangeField(
  value: _range, onChanged: (r) => …,
  borderRadius: BorderRadius.circular(18),
  textStyle: const TextStyle(fontWeight: FontWeight.w600),
  decoration: const InputDecoration(labelText: 'Period', filled: true),
);

Drive the inline picker imperatively:

final c = DateRangePickerController();
DateRangePickerView(controller: c, onChanged: (r) => …);
c.setRange(DateRangePreset.lastDays(7).build(DateTime.now()));
c.goToMonth(DateTime(2027, 1));
c.clear();

Modes

config: DateRangePickerConfig(mode: DateRangeMode.birthday)

Mode	Gives you
range	A span (default)
single	One day
birthday	Year → month → day, blocks the future, range.ageInYears()
dateTime	A time on each end → 2026-08-05 09:30
week	One tap selects the whole week
multiple	Toggle loose days → PickedDates

Standalone pickers

Each opens on its own and returns its own value (null if cancelled):

final time  = await DateRangePickerTime(context, initialTime: TimeOfDay.now()); // TimeOfDay?
final span  = await DateRangePickerTimeRange(context);                          // ({start, end})?
final dur   = await DateRangePickerDuration(context);                           // Duration?
final month = await DateRangePickerMonth(context);                             // DateTime?
final year  = await DateRangePickerYear(context);                              // int?
final dates = await DateRangePickerMultiple(context);                          // PickedDates?

if (time != null) print(time.format(context));   // 9:00 AM

Style the time-based pickers with TimePickerStyle.from(accent: Colors.indigo) (also .rounded() / .minimal() / .compact()), and set minuteInterval / use24HourFormat as needed.

Options — DateRangePickerConfig

Option	Does
mode	Selection mode (above). Default range
minDate / maxDate	Selectable bounds; outside days greyed
minRangeLength / maxRangeLength	Length limits, enforced while picking
selectableDayPredicate	Per-day filter (weekends, holidays, booked)
disabledRanges	Block whole DateTimeRanges
firstDayOfWeek	First column. Default Monday
visibleMonths	Months side by side; collapses when narrow
autoApply	Confirm on complete selection
presets	Chip row; [] hides it
showTodayPreset / showThisWeekPreset / showThisMonthPreset / showLast7DaysPreset / showLast30DaysPreset	Toggle each default chip
showHeader / showDayCount / showClearButton	Chrome toggles
highlightToday	Ring around today
enableYearPicker / enableSwipe	Tap title for years; swipe to page
showWeekNumbers	ISO-8601 week column
dayBuilder	Custom day cell (DayCellDetails)
eventLoader	Events per day, drawn as dots
dayHighlightColor	Per-day background tint
firstYear / lastYear	Year-grid bounds
headerDateFormat / monthTitleFormat	intl date skeletons
minuteInterval	Time steps in dateTime — 15 → :00 :15 :30 :45
use24HourFormat	Force a 24-hour clock
initialStartTime / initialEndTime	Default endpoint times
locale	Names and formats
labels	Every UI string (Localisation)

Presets

Today, This Week, This Month, Last 7 & Last 30 Days by default — hide one with showLast7DaysPreset: false, or bring your own:

presets: [
  DateRangePreset.lastDays(90),
  DateRangePreset(label: 'Q1', build: (now) =>
      PickedDateRange(DateTime(now.year), DateTime(now.year, 3, 31))),
]

Built in: today, yesterday, thisWeek, lastWeek, thisMonth, lastMonth, thisYear, lastDays(n), nextDays(n) — clamped to your bounds.

Theming

Skip it and it follows your app, light or dark. 12 colours, 7 radii, 6 text styles.

theme: DateRangePickerTheme.from(primary: Colors.teal)   // one colour
theme: DateRangePickerTheme.rounded()                    // or .minimal() / .compact()

cupertinoDateRangePickerTheme() mirrors the iOS palette for DateRangePickerCupertino.

Localisation

Names follow the device locale; every string is overridable — use a built-in bundle (en es fr de pt it tr ar) or set fields:

labels: DateRangePickerLabels.forLocale('es')
labels: const DateRangePickerLabels(from: 'From', to: 'To', apply: 'Apply')

Result

range.start / range.end     // ordered; end is never before start
range.days                  // inclusive count (one day = 1)
range.duration;             range.contains(day);
range.toList();             range.toDateTimeRange();   range.toJson();
range.hasTime;  range.startTime;  range.endTime;  range.ageInYears();  range.isSingleDay;

Multi-date returns PickedDates (dates, count, contains, toggle, toJson).
