How to format DateTime in Flutter

Question

I am trying to display the current DateTime in a Text widget after tapping on a button. The following works, but I\'d like to change the format.

Answer 1

You can use DateFormat from intl package.

import 'package:intl/intl.dart';

DateTime now = DateTime.now();
String formattedDate = DateFormat('yyyy-MM-dd – kk:mm').format(now);

Answer 2

Use String split method to remove :00.000

var formatedTime = currentTime.toString().split(':')
Text(formatedTime[0])

======= OR USE BELOW code for YYYY-MM-DD HH:MM:SS format without using library ====

var stringList =  DateTime.now().toIso8601String().split(new RegExp(r"[T\.]"));
var formatedDate = "${stringList[0]} ${stringList[1]}";

Answer 3

With this approach, there is no need to import any library.

DateTime now = DateTime.now();

String convertedDateTime = "${now.year.toString()}-${now.month.toString().padLeft(2,'0')}-${now.day.toString().padLeft(2,'0')} ${now.hour.toString()}-${now.minute.toString()}";

Answer 4

Use this function

todayDate() {
    var now = new DateTime.now();
    var formatter = new DateFormat('dd-MM-yyyy');
    String formattedTime = DateFormat('kk:mm:a').format(now);
    String formattedDate = formatter.format(now);
    print(formattedTime);
    print(formattedDate);
  }

Output:

08:41:AM
21-12-2019

Answer 5

Try out this package, Jiffy, it also runs on top of Intl, but makes it easier using momentjs syntax. See below

import 'package:jiffy/jiffy.dart';   

var now = Jiffy().format("yyyy-MM-dd HH:mm:ss");

You can also do the following

var a = Jiffy().yMMMMd; // October 18, 2019

And you can also pass in your DateTime object, A string and an array

var a = Jiffy(DateTime(2019, 10, 18)).yMMMMd; // October 18, 2019

var a = Jiffy("2019-10-18").yMMMMd; // October 18, 2019

var a = Jiffy([2019, 10, 18]).yMMMMd; // October 18, 2019

Answer 6

You can also use this syntax. For YYYY-MM-JJ HH-MM:

var now = DateTime.now();
var month = now.month.toString().padLeft(2, '0');
var day = now.day.toString().padLeft(2, '0');
var text = '${now.year}-$month-$day ${now.hour}:${now.minute}';
