I would like to know how a date such as "2022-07-17T01:46:12.632892+05:30" be converted to a Human Readable date in DD/MM/YYYY and hh:mm:ss format? I probably have not surfed through a lot of other questions and suggestions on the Internet but the ones I came across were not of any help. Also, what are such date formats(like the one in question) called?
It is rather straightforward using DateFormat from the package intl which comes with Flutter:
import 'package:intl/intl.dart';
void main() {
final dateTime = DateTime.parse('2022-07-17T01:46:12.632892+05:30').toUtc();
final dateFormat = DateFormat('dd/MM/yyyy HH:mm:ss');
print(dateFormat.format(dateTime)); // 16/07/2022 20:16:12
}
The time has here been converted to UTC to make the example the same for all readers. If not, the created DateTime would be localtime which uses the timezone on the device which the program are running.
If you want to print the time using the timezone offset of 5 hours and 30 minutes, you can do something like this:
import 'package:intl/intl.dart';
void main() {
final dateTime = DateTime.parse('2022-07-17T01:46:12.632892+05:30').toUtc();
final dateFormat = DateFormat('dd/MM/yyyy HH:mm:ss');
print(dateFormat.format(dateTime.add(const Duration(hours: 5, minutes: 30))));
// 17/07/2022 01:46:12
}

i would like some help on this i actually use TZDateTime and also with specific location now i would to remove the end of the result like .123436+100 from it
final dateTime = TZDateTime.now(getLocation(box.read(timezone)));
the result always i get is something like this
2022-04-20 17:42:05.032173+1000
but i want is only like this
2022-04-20 17:42:05
how can i remove that actually
I haven't used TZDateTime before but I think it's the same as DateTime. By using DateFormat from intl you can format the string as you want.
ps1: in case TZDateTime cant parse directly, you can turn it to string and pass to DateTime.parse.
ps2: this answer of mine is an idea and has not been tested correctly, sorry if it didn't help you.
import 'package:intl/intl.dart';
void main() {
var time = DateTime.parse('2022-04-20 17:42:05.032173+1000');
var fm = DateFormat('yyyy-MM-dd hh:mm:ss');
print(fm.format(time)); // -> 2022-04-20 07:42:05
}
how to show datetime(timestamp format) form firebase firestore in (dd/mm/yy, hh:mm:ss) in flutter.
please see the images attachedfirebase firestore data
and my code is my code in vscode
You can simply call toDate() function to the dateTime or your firebase timestamp.
You can also convert them into desired format by using DateFormat class
Here is a small function which will return time like 12:37 AM :
import 'package:intl/intl.dart'; //add this import statement for using DateTime class
String getTime(var time) {
final DateFormat formatter = DateFormat('dd/MM/yyyy, hh:mm:ss aa'); //your date format here
var date = time.toDate();
return formatter.format(date);
}
This function will convert your timestamp object to provided format
eg.: July 23, 2021 at 9:22:29 PM UTC+5:30 -> 23/07/2021, 9:22:29 PM
You can refer this document for detailed date formatting.
You can first parse the date to get a DateTime object by using DateTime.parse(string_from_firebase).
Then use the DateFormat class from the intl package.
final DateTime dateToBeFormatted = DateTime.parse(string);
final df = DateFormat('dd/MM/yyyy');
final formatted = df.format(dateToBeFormatted);
I am trying to millisecondsSinceEpoch 1619451874928 to dd-MM-YYYY format in flutter. Is there any method that does that?
How to convert eg. 1619451874928 to 27 March 2021
import 'package:intl/intl.dart';
void main() {
final dateTime = DateTime.fromMillisecondsSinceEpoch(1619451874928);
final dateTimeString = DateFormat("dd-MM-yyyy").format(dateTime);
print(dateTimeString);
final dateTimeStringLong = DateFormat("dd MMMM yyyy").format(dateTime);
print(dateTimeStringLong);
}
dateTimeString will be in format you requested, i.e. "dd-MM-yyyy". Hovever in order to get date in format of "27 March 2021", you should use following pattern
"dd MMMM yyyy".
Please note that you should also include and import package 'package:intl/intl.dart'
You can use this:
DateFormat("dd MM yyyy").format((DateTime.fromMillisecondsSinceEpoch(1619451874928)));
I searched a lot without finding a solution.
I would like to get the current Date time format by locale (https://en.wikipedia.org/wiki/Date_format_by_country)
For example, if my locale zone in the U.S. I would like to get "MDY" if Europe "DMY" and so on.
Is there a way to get this?
You can use the intl package and try this:
DateFormat.yMd(Localizations.localeOf(context).languageCode).format(date);
Just simply give the formate style and then fetch it..
DateFormat("dd/MMM/yyyy").format(date);
intl is not enough.
intl will only format a DateTime with a given date format String such as dd/MMM/yyyy.
In order to get users preferred date format String
you can use system_date_format
Here is an example of how to combine intl with system_date_format to achieve your goal.
final date = DateTime.now();
final dateFormatString = SystemDateTimeFormat().dateFormat;
print(dateFormatString ); // e.g. "M/d/yy"
final formattedDateString = DateFormat(dateFormatString).format(date);
print(formattedDateString ); // "2/14/23"
You could use the dateTimeSymbolMap:
import 'package:intl/date_symbol_data_local.dart';
import 'package:intl/date_symbols.dart';
void main(List<String> args) {
var dateTimeSymbolMap2 = dateTimeSymbolMap()['en'] as DateSymbols;
print(dateTimeSymbolMap2.DATEFORMATS); // prints [EEEE, MMMM d, y, MMMM d, y, MMM d, y, M/d/yy]
}
I have a date-time in epoch format: 1633247247
I want to convert it into timestamps like this: Sunday, 3 October 2021 or just October 3 2021
I am writing this code
final DateTime timeStamp = DateTime.fromMillisecondsSinceEpoch(1633247247);
But it is returning 1970-01-19 18:25:11.247
Edit I ran this code
final DateTime timeStamp = DateTime.fromMillisecondsSinceEpoch(1633247247 * 1000);
Got the output in datetime. I am now trying to convert into string
String formattedDate = DateFormat('yyyy-MM-dd – kk:mm').format(date);
It gives this error The instance member 'date' can't be accessed in an initializer.
It represent to milliseconds, you need to multiple it with 1000 like below :
final DateTime timeStamp = DateTime.fromMillisecondsSinceEpoch(1633247247 * 1000);
It seems like that the time you've is 'seconds since epoch' so just multiplying by 1000 should give you the correct time.
final DateTime timeStamp = DateTime.fromMillisecondsSinceEpoch(1633247247 * 1000);
Download and Import
intl Pacakge
import 'package:intl/intl.dart';
Initialize a variable
String datetime;
Get Current date and conversion
Future<void> Datetimes() async{
setState(() {
DateTime now = DateTime.now();
String formattedDate = DateFormat('EEEE d MMM hh:mm:ss').format(now);
datetime=formattedDate;
});
}
Output
Saturday 3 oct 2:07:29
