Format Dates

date_format

A simple API to format dates.

Usage

Use formatDate function to format a DateTime object.

print(formatDate(DateTime(1989, 02, 21), [yyyy, '-', mm, '-', dd]));

Output:

1989-02-21

Long month names

print(formatDate(DateTime(1989, 2, 21), [yy, '-', M, '-', d]));

Output:

89-feb-21

Time parts

print(formatDate(
      DateTime(1989, 02, 1, 15, 40, 10), [HH, ':', nn, ':', ss]));

Output:

15:40:10

Timezone

print(formatDate(
      DateTime(1989, 02, 1, 15, 40, 10), [HH, ':', nn, ':', ss, z]));

Output:

15:40:10+0100

date_format's Issues

Noon shows up as "0PM", but should be "12PM"

I'm formatting a DateTime object that shows up in Linux as 'Mon Nov 5 12:00:00 EST 2018'. In my app, I'm formatting it with '[h,am]', and it outputs "0PM", when I would expect '12PM'. In the code, I see writing AM or PM based on: date.hour date.hour < 12 ? 'AM' : 'PM'. Maybe this should be "<="? Or, should the outputting of the hour not be a plain "hour % 12", but if hour%12==0, then add 12? I suspect this would also fix midnight coming out as "0AM". Thanks.

Requirement for adding 'st/nd/rd/th' suffix for the days

string with NUlL value

Some API endpoints will return a data string with the value NULL because it is allowed in database.
In that case fluter will throw an error.

Null safety support

Enhancement: Any possible of adding relative formatting

Not sure how this would work but I need relative formatting with a fall back to normal date formatting.

Example:
Today @ 11:15 AM which would fall back to 11/23/2022 @ 11:15 AM if that is not today. Same for yesterday and tomorrow.

You want FrenchDateLocale : voilà !

there is more than to integrate :

`import 'package:date_format/date_format.dart';

class FrenchDateLocale implements DateLocale {
const FrenchDateLocale();

final List monthsShort = const [
'Jan',
'Féb',
'Mar',
'Avr',
'Mai',
'Juin',
'Juil',
'Aoû',
'Sep',
'Oct',
'Nov',
'Déc'
];

final List monthsLong = const [
'Janvier',
'Février',
'Mars',
'Avril',
'Mai',
'Juin',
'Juillet',
'Août',
'Septembre',
'Octobre',
'Novembre',
'Décembre'
];

final List daysShort = const [
'Lun',
'Mar',
'Mer',
'Jeu',
'Ven',
'Sam',
'Dim'
];

final List daysLong = const [
'Lundì',
'Mardì',
'Mercredì',
'Jeudi',
'Vendredi',
'Samedi',
'Dimanche'
];

//don’t exists in France, we are in 24 hours per day
@OverRide
String get am => "AM";

@OverRide
String get pm => "PM";
}`

about the weekday, we cannot get the day 'Friday' .[version 1.0.8]

I don't know whether there is something wrong with this package when using such code:
formDate(DateTime(DateTime.now().weekday),[DD])

things like that:
formDate(DateTime(5),[DD]), the result is Saturday;
formDate(DateTime(6),[DD]), the result is Sunday;
formDate(DateTime(7),[DD]), the result is Monday;
and, I tried the argument from 1 to 7, there is no Friday.

Help needed

Hello @tejainece,

Sorry to come here to send you a message but you seem to be active on this repository.

I really need updates on the Pull Request for Jaguar ORM for Flutter !

I would appreciate an update very much,
Thank you in advance,

Alex

Allow the format be specified as a single string

The current formatting method is a little painful

  var _message = '${formatDate(DateTime.now(), [
        'yy',
        '-',
        'M',
        '-',
        'd',
        ' ',
        'h',
        ':',
        'm',
        ':',
        's'
      ])} $message}';

It would be nicer if you could do:

print(${formatDate(DateTime.now(), 'yy-M-d h:m:s')}');

Locale

Didn't find a way to replace the months name. There is any way?

reamde examples are incorrect

All of the examples on you readme page are incorrect as you have forgotten to quote the value:

print(formatDate(DateTime(1989, 02, 21), [yyyy, '-', mm, '-', dd]));

should read

print(formatDate(DateTime(1989, 02, 21), ['yyyy', '-', 'mm', '-', 'dd]'));

Supporting diffrent languages form months and days names

Does this plugin support German and Arabic names for different days and months?

Thur error?

final List daysShort = const [
'Mon',
'Tue',
'Wed',
'Thur',
'Fri',
'Sat',
'Sun'
];

error: request time Thur, 03 Nov 2022 03:02:24 GMT not follow RFC822 spec
Thur -> Thu ?

thank you for the package but how i can use it in code?

please give me an example in code.
practical example.
i am still learning.

error: The name 'Locale' is defined in the libraries 'dart:ui' and 'package:date_format/src/locale/locale.dart'. (ambiguous_export at [itest] lib/common/index_all.dart:48)

French locale is not exported

The newly added French locale file is not imported along with other locales in locale.dart file. Please provide a fix to this

yyyy in date_format_base.dart must be in uppercase

The String yyyy (from line 10 of date_format_base) return "yyyy" but when i call the date i get 10/05/yyyy if i replace it by "YYYY" it is working as expected
