Flutter/Dart Extract just the Date and Time?

How would I either reformat, convert or extract just the date and time from this string in Dart/Flutter? The String comes from the default timestamp in my MySQL database;

2021-08-11T11:38:09.000Z

So what I need is something like this;

  2021-08-11 11:38

I was thinking perhaps something like;

final String? shortime = timestamp?.replaceAll(RegExp(''), '') ?? '';

But I'm not sure what to use as the regex.

you can use this code:

DateTime x = DateTime.parse("2021-08-11T11:38:09.000Z");

then create a function to check the input number:

String checkNum(int x){
   return x<10?"0${x}":x.toString();
}

now you can use this function as follow:

  print(checkNum(x.year));
  print(checkNum(x.month)); // and so on...

let me know if you had any related problems. here is an example: enter image description here.

Since the provided timestamp is supported by DateTime.parse you could do something like this:

void main() {
  final dateTime = DateTime.parse('2021-08-11T11:38:09.000Z');
  print(convertDateTimeToString(dateTime)); // 2021-08-11 11:38
}

String convertDateTimeToString(DateTime dt) => '${dt.year}-'
    '${dt.month.toString().padLeft(2, '0')}-'
    '${dt.day.toString().padLeft(2, '0')} '
    '${dt.hour.toString().padLeft(2, '0')}:'
    '${dt.minute.toString().padLeft(2, '0')}';

Alternative, you can use a package like intl which supports formatting DateTime using a formatting pattern:

import 'package:intl/intl.dart';

void main() {
  final dateTime = DateTime.parse('2021-08-11T11:38:09.000Z');
  final format = DateFormat('yyyy-MM-dd HH:mm');
  print(format.format(dateTime)); // 2021-08-11 11:38
}
