simple_moment Pub Build Status

A simple implementation of the Moment.js features for relative time in Dart.

Usage

A simple usage example:

import 'package:simple_moment/simple_moment.dart';

main() {
    var secondsToAdd = Duration(seconds: 10);
    var dateForComparison = DateTime.now().add(secondsToAdd);
    var moment = Moment.now();

    // should print "in a few seconds"
    print(moment.from(dateForComparison));
    
    Moment rawDate = Moment.parse("2020-07-03");
      // should print "2020-08-03 00:00:00.000
      print(rawDate.add(months: 1));
    
      // should print "2019-07-03 00:00:00.000
      print(rawDate.subtract(years: 1));
    
      //should print "03-07-2020 00:00"
      print(rawDate.format("dd-MM-yyyy HH:mm"));
}

Locales

Set the locale for all usages of Moment:

Moment.setLocaleGlobally(new LocaleDe());

Set the locale only for the current instance of Moment:

var moment = new Moment.now().locale(new LocaleDe());

Adding your own locale:

Just create a class that implements ILocaleData and assign that to your Moment instance or set it globally.

Overwriting existing locales:

class ShortLocaleEn extends LocaleEn {
  String get seconds => '%is';

  String get aMinute => '%im';
  String get minutes => '%im';

  String get anHour => '%ih';
  String get hours => '%ih';

  String get aDay => '%id';
  String get days => '%id';
}

Using intl to format dates

// create new Moment instance with german locale
var moment = Moment.now().locale(LocaleDe(), useInFormat: true);

// initialize intl
await initializeDateFormatting(moment.usedLocale.localeString);

// format and print the current month in german
var formattedString = moment.format("LLLL");
print(formattedString);
