unified_fields #

Unified Flutter input widgets—text, numbers, pickers, duration, date & time—and form-aware wrappers that plug into Form with validation, save, reset, and optional shake-on-error feedback. Includes a Gregorian / Jalali (Shamsi) calendar sheet and a vendored scrollable positioned list for large picker lists (no scrollable_positioned_list pub dependency).

Core concepts #

One visual language #

Fields share UnifiedInputDecoration (label, placeholder, labelStyle, fieldStyle, placeholderStyle, radii, validation colors, prefix/suffix) and UnifiedInputBrightness (light / dark palette). For colors that should be the same on every field (disabled chrome, required *, validation red, picker sheet background), wrap your app or a screen in UnifiedInputThemeScope — see Global theme.

Per-state decoration (`decorationSet`) #

Like Material InputDecoration focus/error borders, pass optional layers via decorationSet (or theme-wide fieldDecorationSet). Each layer is a partial UnifiedInputDecoration; unset properties fall back to decoration / palette defaults.

UnifiedTextField(
  decoration: const UnifiedInputDecoration(
    borderSide: BorderSide(color: Colors.grey),
  ),
  decorationSet: UnifiedInputDecorationSet(
    focused: const UnifiedInputDecoration(
      borderSide: BorderSide(color: Colors.blue, width: 1.5),
    ),
    error: const UnifiedInputDecoration(
      borderSide: BorderSide(color: Colors.red),
      validationColor: Colors.red,
    ),
    disabled: const UnifiedInputDecoration(
      backgroundColor: Color(0xFFF5F5F5),
    ),
  ),
)

States: base, focused, valid, error, locked, disabled, loading, readOnly. The valid layer applies only when you define it and validation has passed with no error.

Two usage modes #

Standalone — e.g. UnifiedTextField, UnifiedSinglePickerField: drop into any screen; you own validation if needed.
Under a Form — use UnifiedForm… variants so GlobalKey<FormState> can call validate(), save(), and reset() on the whole form.

`label`, `placeholder`, `isRequired` #

Every field exposes label, placeholder, and isRequired as root-level constructor parameters. They always win over the equivalent values inside UnifiedInputDecoration (which still work as the form-wide default):

UnifiedTextField(
  label: 'Email',
  placeholder: 'name@example.com',
  isRequired: true,
)

Placeholder, label, and focus defaults (0.2.4+) #

Value text style — set on UnifiedInputFieldDefaults (or per field via UnifiedInputDecoration.fieldStyle, UnifiedBaseTextField.style, or style on phone/date fields):

fieldDefaults: const UnifiedInputFieldDefaults(
  textStyle: TextStyle(fontSize: 16, color: Colors.black87),
  textStylePersian: TextStyle(fontFamily: 'KookFaNum'),
),

Applies to text/number fields, UnifiedPhoneField, UnifiedDateField, and UnifiedDateRangeField. When Persian digits are active (Jalali calendar, usePersianDigits, or global Persian mode), textStylePersian is merged onto textStyle (font family, weight, size, etc.).

Placeholder style — set on decoration or theme; inherits field typography (fontFamily, fontSize, …) unless you override:

UnifiedTextField(
  decoration: const UnifiedInputDecoration(
    fieldStyle: TextStyle(fontFamily: 'Vazirmatn', fontSize: 16),
    // placeholder uses Vazirmatn 16 + theme hint color
    placeholderStyle: TextStyle(fontStyle: FontStyle.italic),
  ),
  placeholder: 'Search…',
)

Label style / padding per layout mode — on UnifiedInputFieldDefaults:

fieldDefaults: const UnifiedInputFieldDefaults(
  labelInRowStyle: UnifiedInputLabelModeStyle(
    labelStyle: TextStyle(fontSize: 13, fontWeight: FontWeight.w600),
    labelPadding: EdgeInsets.symmetric(horizontal: 12),
  ),
  labelInColumnStyle: UnifiedInputLabelModeStyle(
    labelPadding: EdgeInsets.only(top: 4, bottom: 6),
  ),
),

Select all on focus — useful for number fields; replace value on first keystroke:

UnifiedNumberField(
  controller: quantityController, // e.g. text: '42'
  selectTextOnFocus: true,
  label: 'Quantity',
)

Or app-wide: UnifiedInputFieldDefaults(selectTextOnFocus: true).

`UnifiedFormField<T>` #

Low-level shell: one FormField<T> + your builder. Prefer the prebuilt UnifiedForm… widgets; use UnifiedFormField when you need a custom control but the same autovalidate, reset sync, and optional shakeOnError.

Form integration (validate · save · reset) #

Wrap inputs in a Form and keep a key:

final _formKey = GlobalKey<FormState>();

@override
Widget build(BuildContext context) {
  return Form(
    key: _formKey,
    child: Column(
      children: [
        UnifiedFormTextField(
          label: 'Name',
          validator: (v) => (v == null || v.isEmpty) ? 'Required' : null,
        ),
        UnifiedFormSinglePickerField<String?>(
          label: 'Country',
          items: countries,
          resetValue: () => null, // on Form reset, clear selection
          validator: (v) => v == null ? 'Pick one' : null,
        ),
        FilledButton(
          onPressed: () {
            if (_formKey.currentState!.validate()) {
              _formKey.currentState!.save();
            }
          },
          child: const Text('Submit'),
        ),
      ],
    ),
  );
}

Reset behavior — `UnifiedFormResetValue<T>` #

typedef UnifiedFormResetValue<T> = T Function();

You pass	On `FormState.reset`
`resetValue: null` (default)	Field value is not forced by reset (baseline tracks live value / controller).
`resetValue: () => ''`	Text / number string resets to empty.
`resetValue: () => null`	Nullable picker / date clears to null (use nullable generic, e.g. `UnifiedFormSinglePickerField<MyEnum?>`).
`resetValue: () => model.defaultX`	Restores that snapshot (pass a new closure if the snapshot should change).
Lists	`UnifiedFormMultiPickerField`: `resetValue: () => const <T>[]` or `() => myList`

Nullable return type is carried by T on the picker (e.g. RoastLevel?), not by T? on the typedef.

Shake on validation error #

Any UnifiedForm… widget and UnifiedFormField accept shakeOnError (default false). When true, the field runs a short horizontal shake the first time hasError goes from false to true (typical failed validate()).

UnifiedFormTextField(
  label: 'Email',
  shakeOnError: true,
  validator: (v) => v!.contains('@') ? null : 'Invalid',
)

Date & calendar #

Sheet API #

showUnifiedFieldsDatePicker — returns DateTime?.
showUnifiedFieldsDatePickerRange — returns DateTimeRange?.

Presentation: bottom sheet on smaller widths; centered dialog when context.unifiedFieldsUseDialogLayout is true (see UnifiedFieldsContextX — width ≥ 900).

Granularity (`UnifiedFieldsDatePickerGranularity`) #

day — full month grid (default).
month — pick first day of month in range.
year — pick first day of year in range.

Calendars (`UnifiedFieldsCalendarKind`) #

Users can switch Gregorian vs Jalali (Shamsi) when showCalendarKindToggle is true. Jalali math uses the shamsi_date package.

Widgets #

UnifiedDateField / UnifiedFormDateField — text field + tap to open picker.
UnifiedDateRangeField / UnifiedFormDateRangeField — range in one field.

Picker style (`UnifiedFieldsDatePickerStyle`) #

Style	UI
`calendar` (default)	Month grid (day granularity) or year/month lists
`wheels`	Scroll wheels left→right: year · month · day (subset per `pickerGranularity`)

Both styles support Gregorian / Shamsi when showCalendarKindToggle is true. In Shamsi wheel mode, column headers use سال / ماه / روز (customize via UnifiedFieldsStrings). Set showWeekdayInWheel: false to show only the day numeral; weekday + day use fixed column widths on UnifiedFieldsDateWheelStyle.

Calendar today is shown as a hollow circle (same shape as the selected day fill).

UnifiedDateField(
  label: 'Birth date',
  pickerStyle: UnifiedFieldsDatePickerStyle.wheels,
  showWeekdayInWheel: true,
  initialCalendarKind: UnifiedFieldsCalendarKind.jalali,
  pickerGranularity: UnifiedFieldsDatePickerGranularity.day,
)

// Same parameters on the Form wrapper:
UnifiedFormDateField(
  label: 'Birth date',
  pickerStyle: UnifiedFieldsDatePickerStyle.wheels,
  wheelStyle: null, // optional; auto-themed when omitted
)

Date ranges still use the calendar sheet (showUnifiedFieldsDatePickerRange).

Wheel chrome is themed automatically (UnifiedFieldsDateWheelStyle.resolve). Pass optional wheelStyle: only when you need custom colors or zoom.

Date picker styling (`UnifiedInputDatePickerStyle`) #

Set calendar / sheet chrome on UnifiedInputThemeData.datePickerStyle or per field via datePickerStyle: on UnifiedDateField, UnifiedDateRangeField, UnifiedFormDateField, and showUnifiedFieldsDatePicker.

Controls sheet background, title / weekday / day colors and font sizes, range highlight, month-year jump grid, year list, Gregorian/Shamsi toggle, confirm/cancel buttons, optional shamsiTextStyle (merged when the picker is in Jalali mode — use for Persian font family / size), nested wheelStyle for wheel pickers, and yearStripStyle for the horizontal year strip (mouse wheel/drag scroll, optional center zoom + edge fade — falls back to wheelStyle fade/magnification when unset).

UnifiedInputThemeScope(
  data: UnifiedInputThemeData(
    datePickerStyle: UnifiedInputDatePickerStyle(
      sheetBackgroundColor: Color(0xFFF5F5F5),
      dayTextColor: Colors.black87,
      daySelectedBackgroundColor: Colors.indigo,
      daySelectedTextColor: Colors.white,
      dayFontSize: 15,
      weekdayTextStyle: TextStyle(fontSize: 11, fontWeight: FontWeight.w600),
      titleStyle: TextStyle(fontSize: 18, fontWeight: FontWeight.bold),
      shamsiTextStyle: TextStyle(fontFamily: 'KookFaNum', fontSize: 16),
      yearStripStyle: UnifiedFieldsDateYearStripStyle(
        magnification: 1.15,
        showFade: true,
      ),
    ),
  ),
  child: myForm,
)

UnifiedDateField(
  label: 'Due date',
  datePickerStyle: UnifiedInputDatePickerStyle(
    daySelectedBackgroundColor: Colors.teal,
  ), // merges on top of theme
)

Jalali field text: when initialCalendarKind / active kind is jalali, the field shows Shamsi-formatted text (e.g. ۱۳,مرداد ۱۴۰۳) after pick, not a Gregorian DateFormat. initialCalendarKind: jalali applies to both calendar grid and wheel pickers (0.1.4).

UnifiedDateField(
  label: 'Event',
  initialCalendarKind: UnifiedFieldsCalendarKind.jalali,
  pickerStyle: UnifiedFieldsDatePickerStyle.calendar, // grid respects jalali
)

Time #

UnifiedTimeOfDayField / UnifiedFormTimeOfDayField — display + edit time with unified chrome.
showUnifiedFieldsTimePicker — bottom sheet with UnifiedFieldsTimePickerStyle.dial (Material) or wheels (H:M:S scroll wheels).
TimePickerUtils.show(context, …) — forwards to showUnifiedFieldsTimePicker (wheels by default in recent versions; pass pickerStyle to use the platform dial).

Picker style (`UnifiedFieldsTimePickerStyle`) #

Style	UI
`dial`	Platform `showTimePicker`
`wheels`	Scroll wheels for hour · minute · (optional) second

Granularity (`UnifiedFieldsTimeGranularity`) #

hours — hour wheel only
hoursMinutes — hour + minute (default for wheels)
hoursMinutesSeconds — hour + minute + second

Wheels support Gregorian / Shamsi digit toggle via initialCalendarKind and showCalendarKindToggle (same idea as date/duration wheels).

UnifiedTimeOfDayField(
  label: 'Start time',
  pickerStyle: UnifiedFieldsTimePickerStyle.wheels,
  pickerGranularity: UnifiedFieldsTimeGranularity.hoursMinutesSeconds,
  initialCalendarKind: UnifiedFieldsCalendarKind.jalali,
)

Custom wheel picker (`CustomWheelPicker`) #

Multi-column scroll wheels with the same sheet chrome as date/duration pickers. Columns and values are maps keyed by index (not variadic generics):

CustomWheelPicker(
  label: 'Line item',
  wheelLayout: CustomWheelPickerWheelLayout.vertical, // or .horizontal
  columns: {
    0: CustomWheelPickerColumn.typed<int>(
      options: [1, 2, 3, 5],
      label: 'Qty',
      valueToString: (v) => '$v',
    ),
    1: CustomWheelPickerColumn.typed<String>(
      options: ['S', 'M', 'L'],
      label: 'Size',
    ),
  },
  value: {0: 2, 1: 'L'},
  onChanged: (map) => setState(() => _selection = map),
  wheelStyle: UnifiedFieldsDateWheelStyle(magnification: 1.15),
)

Standalone sheet: showCustomWheelPicker(context: context, columns: …, value: …).

Sheet chrome and modal behavior use the same APIs as list pickers (see Picker sheet chrome below): pickerSheetStyle, pickerSheetModalSettings, and nested basePickerSheetStyle / modalSettings.

Duration #

UnifiedDurationField / UnifiedFormDurationField — tap to open a duration sheet; optional manual edit of the formatted string.
showUnifiedFieldsDurationPicker — imperative sheet API (also used internally by the field).

Picker style (`UnifiedFieldsDurationPickerStyle`) #

Style	UI
`wheels` (default)	Unified scroll wheels (themed like date/time wheels)
`cupertino`	Legacy Cupertino-style H:M:S wheels

Granularity vs custom columns #

Use granularity for the classic fixed shapes when you do not need year/month/week:

`UnifiedDurationGranularity`	Columns	Display example
`hours`	hour	`05`
`hoursMinutes`	hour, minute	`05:30`
`hoursMinutesSeconds`	hour, minute, second	`05:30:45`
`minutesSeconds`	minute, second (minutes may exceed 59)	`90:00`

Use pickerColumns when you need calendar-style units in a custom order (largest unit first, left → right on the wheel):

UnifiedDurationField(
  label: 'Tenure',
  pickerColumns: [
    UnifiedFieldsDurationColumn.year,
    UnifiedFieldsDurationColumn.week,
    UnifiedFieldsDurationColumn.day,
    UnifiedFieldsDurationColumn.hour,
  ],
  // or: UnifiedFieldsDurationColumnPresets.yearsWeeksDaysHours
  initialCalendarKind: UnifiedFieldsCalendarKind.jalali,
  min: Duration.zero,
  max: const Duration(days: 365 * 10),
)

UnifiedFieldsDurationColumn: year, month, week, day, hour, minute, second.

Presets on UnifiedFieldsDurationColumnPresets: yearsMonthsDays, yearsWeeksDaysHours, hoursMinutesSeconds, minutesSeconds.

When pickerColumns is set, it overrides granularity for both the picker and display format. Wheel ranges: year 0…999, month 0…11, week 0…4 (when used with coarser calendar columns). Totals still compose with year = 365 days, month = 30 days, week = 7 days per unit (standard day/hour/minute/second otherwise); the result is clamped to max on confirm.

Helpers: unifiedFormatDuration, unifiedTryParseDuration, composeUnifiedDuration, decomposeUnifiedDuration, formatUnifiedDurationColumns.

Pickers #

Widget	Data
`UnifiedSinglePickerField<T>`	`T?` selection, searchable list, suggestions
`UnifiedMultiPickerField<T>`	`List<T>`, checkboxes in sheet
`UnifiedAsyncPickerField<T>`	Items from `Future<List<T>> Function()`
`UnifiedAsyncMultiPickerField<T>`	Same, multi-select

PickerSheetWidget / MultiPickerSheetWidget are the sheet implementations (scrollable list + search). Every picker field and UnifiedForm*Picker* wrapper supports the same sheet customization:

Parameter	Purpose
`valueToString`	Display label for field text, search, and default list rows
`itemToWidget`	Custom list row; default uses `unifiedPickerResolveListItem` → `unifiedPickerDefaultItemWidget`
`searchBuilder`	Custom searchable text per item (defaults to `valueToString` / `unifiedPickerItemLabel`)
`gridItemBuilder`	Custom grid tile; sheet uses `GridView` instead of a list
`gridDelegate`	Full `SliverGridDelegate` (max extent, fixed count, spacing, aspect ratio, …). Omit to use `unifiedPickerDefaultGridDelegate()`
`pickerHeaderStyle` / `pickerSheetStyle`	Per-field sheet chrome (`helpWidget`, `itemOrder`, background, …)
`pickerSheetModalSettings`	Per-field `showModalBottomSheet` flags (wins over `pickerSheetStyle.modalSettings` and theme)

Picker sheet chrome (0.2.6) #

Shared bottom-sheet styling for list pickers, CustomWheelPicker, and related sheets.

UnifiedBasePickerSheetStyle — padding, colors, and radii:

Property	Effect
`sheetBackgroundColor`	Sheet surface (header gaps + footer)
`sheetBorderRadius`	Modal shape and clip (all corners, including footer)
`contentPadding`	Padding around wheel / list body
`footerPadding`	Cancel / confirm row
`panelPadding`	Inside the wheel panel
`panelBackgroundColor`	Wheel panel fill (e.g. green content area)
`panelBorderRadius` / `panelBorderColor` / `panelBorderWidth`	Wheel panel border

Set on UnifiedInputThemeData.basePickerSheetStyle or UnifiedPickerSheetStyle.basePickerSheetStyle.

UnifiedPickerSheetModalSettings — modal presentation:

Property	Maps to
`isScrollControlled`	Full-height sheet
`isDismissible`	Tap outside / back
`enableDrag`	Drag-to-dismiss (defaults to `isDismissible`)
`useSafeArea`	System bottom inset
`showDragHandle`	Material drag handle

Set on UnifiedInputThemeData.pickerSheetModalSettings, UnifiedPickerSheetStyle.modalSettings, or pickerSheetModalSettings on any picker field.

CustomWheelPicker(
  label: 'Configuration',
  pickerSheetStyle: UnifiedPickerSheetStyle(
    basePickerSheetStyle: UnifiedBasePickerSheetStyle(
      sheetBackgroundColor: Colors.blue,
      sheetBorderRadius: BorderRadius.circular(16),
      panelBackgroundColor: Colors.green,
      panelBorderRadius: BorderRadius.circular(12),
      contentPadding: EdgeInsets.zero,
    ),
    modalSettings: UnifiedPickerSheetModalSettings(
      isDismissible: false,
      isScrollControlled: true,
    ),
  ),
  columns: { /* … */ },
  value: {0: 2, 1: 'Large'},
)

Precedence: field pickerSheetModalSettings → pickerSheetStyle.modalSettings → theme → package defaults (isScrollControlled / isDismissible / enableDrag / useSafeArea: true; showDragHandle: false).

Imperative API: showUnifiedFieldsPickerBottomSheet (used internally by list/multi pickers).

List row helpers (0.2.6) #

import 'package:unified_fields/unified_fields.dart';

// Label for field text and search
final label = unifiedPickerItemLabel(country, valueToString: (c) => c.name);

// Default list row when itemToWidget is omitted
itemToWidget: (c) => unifiedPickerDefaultItemWidget(
  c,
  valueToString: (x) => x.name,
),

// Or let the sheet resolve for you (itemToWidget ?? default widget)
unifiedPickerResolveListItem(
  item,
  itemToWidget: customBuilder,
  valueToString: (x) => x.name,
);

Picker sheet header (0.2.3+ layout, 0.2.6 `helpWidget`) #

Reorder title, help, close, and clear with itemOrder. Help is a Widget (helpWidget); helpTextStyle from theme merges via DefaultTextStyle:

pickerHeaderStyle: UnifiedInputPickerHeaderStyle(
  itemOrder: const [
    UnifiedPickerHeaderItem.title,
    UnifiedPickerHeaderItem.help,
    UnifiedPickerHeaderItem.clear,
    UnifiedPickerHeaderItem.close,
  ],
  helpWidget: Text('Pick one option'),
),

Grid (single-select): builder receives (context, index, item, onSelect) — call onSelect to choose and close.

Grid (multi-select): builder receives (context, index, item, isSelected, onSelect) — onSelect toggles selection; user confirms in the sheet footer.

UnifiedMultiPickerField<String>(
  label: 'Tags',
  values: selected,
  items: allTags,
  gridDelegate: unifiedPickerDefaultGridDelegate(crossAxisCount: 3, childAspectRatio: 1.2),
  gridItemBuilder: (context, index, item, isSelected, onSelect) => FilterChip(
    label: Text(item),
    selected: isSelected,
    onSelected: (_) => onSelect(),
  ),
)

Form: use UnifiedFormMultiPickerField (or any other UnifiedForm*Picker*) with the same parameters. Imperative open: fieldController.openPicker(context) or pickerController.openPicker(context) on customizable controllers after bindPicker.

Standalone sheets: showUnifiedSinglePickerSheet / showUnifiedMultiPickerSheet.

Customizable APIs (unified_cutomizable_picker_fields.dart — filename keeps the historical typo cutomizable): single or multi selection with CustomizableSinglePickerController / CustomizableMultiPickerController plus async siblings for remote data. Each controller carries either typed text or the selected value(s); the matching UnifiedFormCustomizable… wrappers expose resetValue snapshots so FormState.reset restores both the mode and the payload in one step.

Phone (`UnifiedPhoneField`) #

International phone input with SVG flags (bundled under assets/flags/countries/), optional dial-code segment, national mask (# = digit), and a default phone suffix icon.

Countries #

Countries are a fixed UnifiedCountry enum (~250 entries) with ISO code, display name, and dial code:

UnifiedCountry.ir.isoCode   // IR
UnifiedCountry.ir.dialCode  // +98
UnifiedCountries.byIso('DE')
UnifiedCountries.matchDialCode('+98912…')
UnifiedCountries.defaults   // all enum values (picker / field default list)

India uses UnifiedCountry.countryIN (in is a reserved Dart name). Regenerate the enum after editing tool/countries.json:

dart run tool/generate_unified_countries.dart

Field usage #

UnifiedPhoneField(
  label: 'Mobile',
  placeholder: '912 123 4567',
  labelMode: UnifiedFieldLabelMode.labelInColumn,
  usePersianDigits: true, // or digitCalendarKind: UnifiedFieldsCalendarKind.jalali
  fixedCountry: UnifiedCountry.ir, // optional: lock dial code
  // showCountryCodeSection: true,
  // editableCountryCode: true, // one field: + dial + national
  fieldController: UnifiedPhoneFieldController(
    initialCountry: UnifiedCountry.ir,
    onChanged: (UnifiedPhoneNumber? n) => debugPrint(n?.e164),
  ),
)

Mode	Behavior
Editable dial code (default when code section is shown)	Single input: `+` + country code + masked national digits
Fixed country (`fixedCountry`)	Flag + dial label + national digits only
Non-editable code section	Dial label (tap opens picker) + national field

Theme phone chrome via UnifiedInputPhoneStyle / UnifiedInputThemeData.phoneStyle (dial-code box, flag size, invalid-code highlight vs message).

Standalone widgets #

UnifiedCountryWidget(country: UnifiedCountry.ae) // flag only (showName defaults to false)
UnifiedCountryWidget(country: UnifiedCountry.ir, showName: true, showDialCode: true)
UnifiedFlag(code: 'IR', size: 28)

final picked = await showUnifiedPhoneCountryPicker(
  context: context,
  countries: UnifiedCountries.defaults,
  usePersianDigits: true,
);

UnifiedPhoneNumber exposes country, nationalDigits, e164, display, and localizedDisplay / localizedE164 when using Persian digits.

Bindings with `UnifiedInputPicker` #

UnifiedInputPicker<T> is a ChangeNotifier holding value, optional errorText, and helpers clear, setError, silentSetValue. Pass it as binding: on fields so UI and domain state stay in sync; form wrappers also write back on save/reset when configured.

Form-aware pickers and date/time fields listen to the binding, so clearing from code updates the visible field:

final country = UnifiedInputPicker<String?>();

UnifiedFormSinglePickerField<String?>(
  label: 'Country',
  binding: country,
  items: countries,
);

// Later — UI and FormField both clear:
country.clear();

You can use binding and fieldController together: the binding holds app state; the typed controller adds picker-specific APIs (openPicker, displayText, sheet options).

AppInputController was renamed in 0.1.4; a deprecated typedef points to UnifiedInputPicker.

Field controllers #

BaseUnifiedFieldController<T> (and typed subclasses) mirror TextEditingController for pickers, dates, numbers, and duration. Pass fieldController: on the matching Unified… widget.

Controller	Field(s)
`UnifiedPickerFieldController<T>`	`UnifiedSinglePickerField`, `UnifiedAsyncPickerField`
`UnifiedMultiPickerFieldController<T>`	`UnifiedMultiPickerField`, `UnifiedAsyncMultiPickerField`
`UnifiedDateFieldController`	`UnifiedDateField`
`UnifiedDateRangeFieldController`	`UnifiedDateRangeField`
`UnifiedTimeOfDayFieldController`	`UnifiedTimeOfDayField`
`UnifiedDurationFieldController`	`UnifiedDurationField`
`UnifiedNumberFieldController`	`UnifiedNumberField`, `UnifiedNumericStepField`

When the field is mounted, openPicker(context) (and async openPickerAsync) use the same code path as a tap—no need to pass items / label again. Off-tree or tests: call bindPicker / bindPickerLabel first, or pass items and label explicitly.

requestFocus() on the controller (or on a binding that shares the attached focus node) focuses the wired field.

UnifiedFormController coordinates multiple controllers for validate/save/reset on a custom form layout.

Field states & label layout #

Shared by UnifiedBaseTextField and every field built on it:

`isDisabled` / `disabled`	Read-only look; when both placeholder and value exist, both are shown (not hidden like a greyed empty field).
`locked`	Blocks interaction; distinct from disabled styling.
`loading`	Small suffix spinner (replaces dropdown/chevron); field does not use full-field overlay or muted disabled colors.
`interactionBlocked`	Absorbs pointer events without disabled chrome—used for pick-only surfaces (date, async picker while idle).
`labelMode` / `labelInRow`	`UnifiedFieldLabelMode`: `floatingLabel` (default), `labelInColumn`, or `labelInRow` (label + body in one bordered row with a vertical divider). Legacy `labelInRow: true` on decoration maps to row mode.

Async pickers set loading: true while itemProvider runs; date fields use interactionBlocked: true so the platform picker still opens without disabled: true. UnifiedPhoneField supports the same label modes plus optional height / width.

UI strings (`UnifiedFieldsStrings`) #

All built-in button and sheet copy (Cancel, Confirm, Clear, Done, Pick, Suggestion, date-picker labels, time hour/minute labels, default duration title) comes from UnifiedFieldsStrings.instance. Override once at startup:

void main() {
  UnifiedFieldsStrings.instance = const UnifiedFieldsStrings(
    cancel: 'لغو',
    confirm: 'تأیید',
    clear: 'پاک کردن',
    pickPrefix: 'انتخاب',
  );
  runApp(const MyApp());
}

Multi-picker titles use multiPickerTitle(label) (default "Pick $label"). UnifiedDatePickerStrings is deprecated and reads from the same instance.

Theming & layout #

UnifiedColors — default static palette used by built-in styles (replace over time with your design tokens or override via UnifiedInputDecoration / Theme).
resolveUnifiedDecoration(context, overrides: …, brightness: …) — merges theme + field overrides (used internally by several fields).
UnifiedFieldsContextX on BuildContext: unifiedFieldsScreenWidth, unifiedFieldsScreenHeight, unifiedFieldsUseDialogLayout, unifiedFieldsPrimaryColor (prefixed to avoid clashing with app extensions).
UnifiedSheetButton — compact primary / outlined actions used inside picker sheets.

Global theme (`UnifiedInputThemeScope`) #

Only child is required. Pass a UnifiedInputThemeData to set shared chrome for every unified field in that subtree (labels, values, placeholders, required icon, errors, suffix icons, picker sheets).

App-wide (recommended) #

Wrap runApp so settings screens and forms inherit the same rules:

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(
    UnifiedInputThemeScope(
      data: const UnifiedInputThemeData(
        requiredIconColor: Color(0xFF1565C0),
        requiredIconSize: 9,
        validationColor: Color(0xFFD32F2F),
        disabledFieldOpacity: 0.38,
        placeholderOpacityWhenDisabled: 0.38,
        pickerSheetBackgroundColor: Color(0xFFF5F7FA),
        defaultSuffixIcons: UnifiedInputDefaultSuffixIcons(
          date: Icons.calendar_month_outlined,
          time: Icons.access_time,
          duration: Icons.timelapse_outlined,
          picker: Icons.unfold_more,
        ),
        pickerHeaderStyle: UnifiedInputPickerHeaderStyle(
          padding: EdgeInsets.fromLTRB(16, 14, 8, 14),
          backgroundColor: Colors.white,
          helpWidget: Text('Optional hint'),
        ),
        datePickerStyle: UnifiedInputDatePickerStyle(
          daySelectedBackgroundColor: Color(0xFF1565C0),
          shamsiTextStyle: TextStyle(fontFamily: 'KookFaNum'),
        ),
        multiPickerCheckboxStyle: UnifiedInputMultiPickerCheckboxStyle(
          borderRadius: 6,
          fillColor: Color(0xFF1565C0),
          checkColor: Colors.white,
        ),
      ),
      child: const MyApp(),
    ),
  );
}

The runnable example/ app uses this pattern in example/lib/main.dart.

Nested scope (one screen or card) #

Inner scopes merge over ancestors — useful for a settings subsection or A/B styling:

UnifiedInputThemeScope(
  data: const UnifiedInputThemeData(
    requiredIconColor: Colors.orange,
    disabledFieldColor: Colors.grey,
    disabledFieldOpacity: 0.5,
  ),
  child: Column(
    children: [
      UnifiedFormTextField(
        label: 'Nickname',
        isRequired: true, // orange * from this scope
      ),
      UnifiedFormTextField(
        label: 'Archived',
        isDisabled: true,
        resetValue: () => 'Read-only',
      ),
    ],
  ),
)

Common `UnifiedInputThemeData` fields #

Field	Effect
`brightnessOverride` / `paletteOverride`	Force light/dark or a full custom palette
`disabledLabelColor` / `disabledLabelOpacity`	Label when `isDisabled` / `disabled`
`disabledFieldColor` / `disabledFieldOpacity`	Input text when disabled
`disabledFieldBackgroundOpacity`	Field body fade when disabled
`lockedLabelColor` / `lockedLabelOpacity`	Label when `locked`
`lockedFieldColor` / `lockedFieldOpacity`	Input text when locked
`lockedFieldBackgroundOpacity`	Body fade when locked
`placeholderColor` / `placeholderOpacity`	Hint when enabled
`placeholderOpacityWhenDisabled`	Hint when disabled
`requiredIcon` / `requiredIconColor` / `requiredIconSize`	Required `*` marker
`validationColor`	Inline errors and error border
`clearButtonColor`	Clear (×) button
`suffixIconColor` / `suffixIconOpacity`	Lock, password, default picker suffixes
`loadingIndicatorColor`	Loading spinner on fields
`pickerSheetBackgroundColor`	Date/time/duration sheets (else `bottomSheetTheme` → palette)
`basePickerSheetStyle`	`UnifiedBasePickerSheetStyle`: sheet/panel padding, radii, colors (list + wheel pickers)
`pickerSheetModalSettings`	`UnifiedPickerSheetModalSettings`: `isScrollControlled`, `isDismissible`, `enableDrag`, `useSafeArea`, `showDragHandle`
`pickerHeaderStyle`	`UnifiedInputPickerHeaderStyle`: `padding`, `backgroundColor`, `titleStyle`, `helpWidget`, `helpTextStyle`, `itemOrder`, `closeButton`, `clearButton`
`multiPickerCheckboxStyle`	`UnifiedInputMultiPickerCheckboxStyle`: `size`, `borderRadius`, `fillColor`, `checkColor`, `borderColor`
`fieldDecorationSet`	Default per-state layers (`focused`, `error`, `disabled`, …) for all fields in the scope
`fieldDefaults`	Default [UnifiedBaseTextField] layout/behavior: `labelMode`, `height`, `borderRadius`, `textStyle` / `textStylePersian`, `placeholderStyle`, per-mode `labelInRowStyle` / `labelInColumnStyle` / `floatingLabelStyle`, `selectTextOnFocus`, `showClearButton`, `autovalidateMode`, …
`datePickerStyle`	[UnifiedInputDatePickerStyle]: sheet background, day/month/year colors, font sizes, toggles, buttons, optional `shamsiTextStyle`; includes optional `wheelStyle`
`defaultSuffixIcons`	Default suffix per field type (`date`, `time`, `duration`, `picker`, …)

Field-level UnifiedInputDecoration / decorationSet / fieldDefaults and per-widget params still win for one-off overrides.

UnifiedInputThemeScope(
  data: UnifiedInputThemeData(
    fieldDefaults: const UnifiedInputFieldDefaults(
      labelMode: UnifiedFieldLabelMode.labelInColumn,
      height: 52,
      textStyle: TextStyle(fontSize: 16, fontWeight: FontWeight.w500),
      textStylePersian: TextStyle(fontSize: 16, fontFamily: 'KookFaNum'),
      placeholderStyle: TextStyle(fontSize: 15, color: Colors.grey),
      labelInColumnStyle: UnifiedInputLabelModeStyle(
        labelPadding: EdgeInsets.only(bottom: 6, top: 4),
        labelStyle: TextStyle(fontWeight: FontWeight.w600),
      ),
      showClearButton: true,
    ),
    fieldDecorationSet: UnifiedInputDecorationSet(
      focused: UnifiedInputDecoration(
        borderSide: BorderSide(color: Colors.blue, width: 1.5),
      ),
    ),
  ),
  child: myForm,
)

Live demos: example/lib/main.dart (app + nested card) and UnifiedInputsShowcasePage (scoped block near the top of the gallery).

Persian digits (`UnifiedFieldsTypography`) #

Shamsi (Jalali) date pickers show Persian numerals (۰–۹) using the bundled KookFaNum font. Override at startup:

void main() {
  UnifiedFieldsTypography.instance = const UnifiedFieldsTypography(
    usePersianDigitsGlobally: true, // all unified text / number fields
    // persianFontFamily: 'YourAppNumFont', // optional
  );
  runApp(const MyApp());
}

By default only Shamsi UI uses Persian digits (usePersianDigitsInShamsi: true). Set usePersianDigitsGlobally: true to apply the font and digit mapping to every field (including UnifiedBaseTextField, numeric step fields, duration wheels, and UnifiedPhoneField).

On the phone field, set usePersianDigits: true or digitCalendarKind: UnifiedFieldsCalendarKind.jalali to localize dial codes and national digits (input accepts ۰–۹). Use UnifiedCountry.localizedDialCode / UnifiedPhoneNumber.localizedDisplay outside the field.

Localization #

Set UnifiedFieldsStrings.instance for package-owned copy (pickers, date sheet, duration sheet, time picker hour/minute fallbacks, wheel headers including Shamsi سال/ماه/روز, duration column headers via durationColumnHeader).
Time picker OK/Cancel use MaterialLocalizations when available.
Clear tooltip on the base text field uses MaterialLocalizations.deleteButtonTooltip (platform).

Try the built-in demo #

UnifiedInputsShowcasePage is a long-form scroll demo with a brightness / palette toggle. Push it from debug menus or a settings screen:

Navigator.of(context).push(
  MaterialPageRoute<void>(
    builder: (_) => const UnifiedInputsShowcasePage(),
  ),
);

A runnable example app lives in example/ — open it with flutter run from that folder. It wraps the app in UnifiedInputThemeScope, shows a nested-scope demo card on the home form, and opens UnifiedInputsShowcasePage from the app bar (includes a dedicated theme-scope section).

Dependencies #

Package	Role
`flutter_svg`	Country flag SVGs in `UnifiedFlag` / phone field
`intl`	Date/number formatting in date fields and picker
`shamsi_date`	Jalali calendar conversion
`collection`	Used by the vendored scrollable list implementation

Async pickers show loading via the field suffix spinner (loading on UnifiedBaseTextField), not a full-field overlay.

Vendored code #

Under lib/src/scrollable_list/ you’ll find a local copy of a scrollable positioned list implementation (same family as the popular package, kept in-tree so this package stays self-contained).

Version #

Current release: 0.2.6 (see pubspec.yaml and pub.dev for the latest). Follow semver when upgrading.

Upgrading to 0.2.6 #

From 0.2.5 or earlier:

UnifiedInputDatePickerStyle — set UnifiedInputThemeData.datePickerStyle or per-field datePickerStyle on UnifiedDateField, UnifiedDateRangeField, UnifiedFormDateField, UnifiedDateFieldController, and showUnifiedFieldsDatePicker / showUnifiedFieldsDatePickerRange. Customize sheet background, day/month/year colors, font sizes, toggles, buttons, cellHeight, dayCircleSize, nested wheelStyle, and yearStripStyle for the horizontal year strip.
shamsiTextStyle — optional on UnifiedInputDatePickerStyle; merged when the picker is in Jalali mode (Persian month names / numerals). Use for fontFamily (e.g. KookFaNum) like textStylePersian on fields.
CustomWheelPicker — multi-column wheel field (columns / value maps, vertical or horizontal layout). Use CustomWheelPickerColumn.typed per column; sheet via showCustomWheelPicker.
UnifiedBasePickerSheetStyle — theme or pickerSheetStyle.basePickerSheetStyle for sheet background, sheetBorderRadius, content/footer/panel padding, and wheel panel colors.
UnifiedPickerSheetModalSettings — theme, pickerSheetStyle.modalSettings, or pickerSheetModalSettings on picker fields for isScrollControlled, isDismissible, enableDrag, useSafeArea, showDragHandle.
Picker list helpers — unifiedPickerItemLabel, unifiedPickerDefaultItemWidget, unifiedPickerResolveListItem. Sheets respect valueToString for default rows; pass valueToString on fields and showUnifiedSinglePickerSheet / showUnifiedMultiPickerSheet.
Breaking: picker helpText → helpWidget — on UnifiedInputPickerHeaderStyle and UnifiedPickerSheetHeader, replace helpText: '…' with helpWidget: Text('…'). helpTextStyle still applies.
UnifiedNumberField / UnifiedNumericStepField — theme fieldDefaults.textStyle now applies (no hardcoded dark text color). Optional per-field style on UnifiedNumberField.

If you are on 0.2.4 or below, also read Upgrading to 0.2.5 (textStyle on phone/date fields).

Upgrading to 0.2.5 #

textStyle / textStylePersian — now apply to UnifiedPhoneField, UnifiedDateField, and UnifiedDateRangeField via fieldDefaults (no per-field hardcoded 14px on dates). Persian mode merges both styles; override one field with style: on the widget or UnifiedInputDecoration.fieldStyle.
UnifiedDateRangeField — optional initialCalendarKind for Jalali digit font / Persian value style when displaying ranges.

Upgrading to 0.2.4 #

placeholderStyle — on UnifiedInputDecoration, UnifiedBaseTextField, or UnifiedInputFieldDefaults. Placeholders copy fieldStyle typography by default; set placeholderStyle only to differ (e.g. italic or lighter color).
Label chrome per mode — labelInRowStyle, labelInColumnStyle, floatingLabelStyle on UnifiedInputFieldDefaults (UnifiedInputLabelModeStyle with labelStyle + labelPadding). Per-field: UnifiedInputDecoration.labelPadding / UnifiedBaseTextField.labelPadding.
selectTextOnFocus — true on UnifiedTextField, UnifiedNumberField, form wrappers, or fieldDefaults so focusing selects the whole value for easy overwrite.

Upgrading to 0.2.3 #

Picker sheets — override sheet background and header per field with pickerSheetBackgroundColor, pickerHeaderStyle (e.g. itemOrder, helpWidget), or bundled pickerSheetStyle. Works on standalone pickers and UnifiedForm*Picker* wrappers without changing global theme.

Upgrading to 0.2.2 #

Number fields — optional stepButtons, stepButtonPlacement, decrementIcon, incrementIcon, and textAlign. Use UnifiedInputDecoration prefix / prefixIcon / suffixIcon alongside step buttons; set suffixWidth / suffixHeight only when you need a fixed suffix box (otherwise custom suffixes size intrinsically).

Upgrading to 0.2.0 #

Theme field defaults — set UnifiedInputThemeData.fieldDefaults (labelMode, height, borders, showClearButton, autovalidateMode, …). See Global theme.
UnifiedBaseTextField — some params are nullable and inherit from theme; isValid(context) now needs a BuildContext.

Upgrading to 0.1.9 #

Per-state decoration — optional decorationSet on any field, or UnifiedInputThemeData.fieldDecorationSet in UnifiedInputThemeScope. Layers: focused, error, valid, locked, disabled, loading, readOnly, base. See Per-state decoration.

Upgrading to 0.1.8 #

Picker grid / custom list — pass itemToWidget, gridItemBuilder, and gridDelegate on any picker field or UnifiedForm*Picker* wrapper; see Pickers. Helpers: unifiedPickerDefaultGridDelegate, showUnifiedSinglePickerSheet, showUnifiedMultiPickerSheet.
CustomizableSinglePickerController.openPicker / CustomizableMultiPickerController.openPicker — call after the field is mounted, or bindPicker / bindAsyncPicker first.
Customizable async/sync pickers: full-field tap opens the sheet when allowFreeText is true; use disabled or isDisabled to block interaction.

Upgrading from 0.1.6 → 0.1.7 #

UnifiedPhoneField, UnifiedCountry enum, UnifiedFlag, and UnifiedCountryWidget — see Phone. Replace any UnifiedPhoneCountry(...) constructor with enum values (e.g. UnifiedCountry.ir; India: UnifiedCountry.countryIN). UnifiedPhoneCountries → UnifiedCountries.
UnifiedFieldLabelMode on fields; legacy decoration labelInRow: true still maps to row mode.

Upgrading from earlier 0.1.x #

Wrap your app (or a screen) in UnifiedInputThemeScope for global disabled/placeholder/required/validation colors, picker sheet background, header padding, and multi-picker checkbox styling — see Global theme.
Replace context.isDesktop / context.width with context.unifiedFieldsUseDialogLayout / context.unifiedFieldsScreenWidth (old names are deprecated).
Duration wheels default to UnifiedFieldsDurationPickerStyle.wheels; use pickerColumns for year/month/week-style columns.
unifiedFormatDuration / unifiedTryParseDuration use named granularity: and optional pickerColumns: / calendarKind:.
Shamsi dates / phone: set initialCalendarKind: jalali or usePersianDigits on the phone field; optional UnifiedFieldsTypography for app-wide Persian digits (KookFaNum font).
