How to subtract 1 day from current date time in dart?

I have a current datetime with followint function :

String cdate = DateFormat("yyyy-MM-dd HH:mm:ss").format(DateTime.now());

Now I want to subtract 1 day or 24 hours from this current date time.

How can i do that?

>Solution :

Don’t manipulate the string, manipulate the date. From docs, adapted:

final now = DateTime.now();
final yesterday = now.subtract(const Duration(days: 1));

Apply the formatting just before you need to display the date, not before.
