Usage

Creating instance

There are multiple ways to create an instance.

// From DateTime
final a = DateTime.now().toMoment();

final b = Moment(DateTime(...));

// This instance won't be affected by global localization!
final c = Moment(b, localization: MomentLocalizations.ko());

Setting global localization

By default, the global localization is en_US.

Moment.setGlobalLocalization(MomentLocalizations.fr());

Relative Duration

Relative durations are rather inprecise. See precise duration for accuracy and flexibility.

Read about thresholds, and more on docs

final yesterday = Moment.now() - const Duration(days: 1);
yesterday.fromNow(); // a day ago

final add5sec = Moment.now().add(const Duration(seconds: 5));
add5sec.fromNow(dropPrefixOrSuffix: true); // a few seconds

Precise duration

You can create localized human-readable duration text with abbreviation, highly-customizable units.

See more on docs. (delimiter, custom units, abbreviation...)

On Duration objects:

Duration(days: 67, hours: 3, minutes: 2).toDurationString(
  MomentLocalizations.de(),
  form: UnitStringForm.mid,
); // in 2 Mo. 7 Tg.

For Moment:

final epoch = Moment.fromMillisecondsSinceEpoch(0);
final now = DateTime(2023, DateTime.july, 14).toMoment();

print(epoch.fromPrecise(now)); // 53 years 7 months ago

Calendar

final Moment now = Moment.now();

print(now.calendar()); // Today at 03:00 PM

Other helpful methods

moment_dart provides numerous convenience methods. Works on both Moment and DateTime.

See all available options in the docs

final now = DateTime.now(); // July 19 2023 03:12 PM (UTC+8)

// ISO week, ISO week year
now.week; // 48
now.weekYear; // 2023

now.isLeapYear; // false

// Date creates new `DateTime` with hours, minutes, etc.. omitted
now.date; // July 19 2023 00:00 AM

now.clone(); // July 19 2023 03:12 PM

now.nextTuesday(); // July 25 2023 03:12 PM

// and many more!
