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

simple_moment

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);

simple_moment's Issues

Format tokens?

What format token are supported to show a date/time in a a specific format? Can't find anything in the readme or docs. Would be awesome if all Moment.js formatting is applicable here as well.

expression of 'fromNow' is correct ?

Usually we want to express past time expression.
For example...

I made a post 2 minutes ago.
Then I open post list.
There should be expression '2 minutes ago'.

But now it shows 'in 2 minutes'.

This is right ?
or we need one more option like 'toNow' ?

What do you think about it ?
Please review it again.

Support dart 2.0

Please provide support for dart 2.0 and make compatible with latest flutter release

Any way to change locale at the moment?

In vanilla moment.js you can change the locale to say “3m” instead of “3 minutes”, “8s” instead of “8 seconds”, etc. by manually redefining the locale function in your JavaScript code. Is there a way to do that here or perhaps in the future?

Missing features from JS

Moment().week
and Moment.isBeforeOrCurrent and variants are not present in the current iteration, currently using implementations from DateTime to handle the gap in the meantime

convert Moment to DateTime

i dont see any way. all it returns is a Moment object

Support month locale

Like the title, it would be awesome if the library can support locale month.
I mean, now it's possible to get the locale but unable to set month local. If set Moment.setLocaleGlobally(locale); and then try to get the month with (see Moment Docs) Moment.now().format('LLLL') you will always get the month in EN locale.

Am I wrong something or for now this feature doesn't exist?

Null safety is needed.

Could you update it ?
