datetime/date_format_preset_utils library
Dashboard date-format presets (short / medium / long) — roadmap #615.
This package deliberately avoids the heavyweight intl dependency, so
localization is supplied by the caller through DateFormatNames rather than
loaded from a locale database. The English names are the default; pass a
localized DateFormatNames to render month and weekday names in any
language while keeping the preset layout fixed.
Classes
- DateFormatNames
- Month and weekday names used by the medium/long presets, injectable so the presets can render in any language without a locale database.
Functions
-
formatDateLong(
DateTime date, {DateFormatNames names = DateFormatNames.english}) → String -
Long preset: weekday, full month, day, year
(e.g.
Wednesday, June 10, 2026). Weekday and month names come fromnames, defaulting to English. Audited: 2026-06-12 11:26 EDT -
formatDateMedium(
DateTime date, {DateFormatNames names = DateFormatNames.english}) → String -
Medium preset: abbreviated month, day, year (e.g.
Jun 10, 2026). Month name comes fromnames, defaulting to English. Audited: 2026-06-12 11:26 EDT -
formatDateShort(
DateTime date) → String -
Short preset: unambiguous ISO-8601 calendar date
yyyy-MM-dd(e.g.2026-06-10). No names, so it is locale-independent and sorts lexically — ideal for compact dashboard columns. Audited: 2026-06-12 11:26 EDT
