How to convert 24/01/2023 into 2023-01-24-CodePudding

I tried converting the date by doing the below code

  DateFormat('yyyy-MM-dd')
              .add_yMMMd()
              .parse((state as SlotRequestPopUpDataLoadedState).date)
              .toString(),
        );

But it throws error

Unhandled Exception: FormatException: Trying to read - from 09/01/2023 at position 3

CodePudding user response：

It looks like you are trying to parse a date string in the format "yyyy-MM-dd" using the add_yMMMd format. This is causing the FormatException because the two formats are incompatible.

To parse a date string in the "yyyy-MM-dd" format, you should use the parse method with the DateFormat("yyyy-MM-dd") formatter. Use this:

DateTime date = DateFormat("yyyy-MM-dd").parse("2023-01-09");

CodePudding user response：

You have this issue because you are trying to parse a date that contains - but your date contains /. Let's say this is your date:

var date = '24/01/2023';

you can convert it like this:

var Dtime = DateFormat('dd-MM-yyyy').parse(date.replaceAll('/', '-'));

print('newDate = ${DateFormat('yyyy-MM-dd').format(Dtime)}'); //newDate = 2023-01-24
