How can I format String '31/12/2023 00:00:00' to 'dd/MM/yyyy' as DateTime then String in Dart?

Question

I stored the date in database as String and call it via model String? myDate;, the data save as 31/12/2023 00:00:00. I want to dispaly in Text widget as 31/12/2023 not 31/12/2023 00:00:00 so I tried to covnert String to DateTime then to String again but the resutl is 2023-12-31 00:00:00.000

var date = '31/12/2023 00:00:00';
DateTime parseDate = intl.DateFormat("dd/MM/yyyy").parse(date);
var inputDate = DateTime.parse(parseDate.toString());
print(inputDate);
//output: 2023-12-31 00:00:00.000

How to achive my goal?

You need to play around your String and convert it to format that intl.DateFormat can use it.

This code solves my problem:

try it in dartpad.dev

import 'package:intl/intl.dart' as intl;

void main() {
    var date = '31/12/2023 00:00:00';
    String dateWithT = "${date.substring(6, 10)}-${date.substring(3, 5)}-${date.substring(0, 2)}T00:00:00.000000Z";
    DateTime parseDate = intl.DateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse(dateWithT);
    var inputDate = DateTime.parse(parseDate.toString());
    var outputFormat = intl.DateFormat('dd/MM/yyyy');
    var outputDate = outputFormat.format(inputDate);
    print(outputDate);
}
