Flutter – get previous 5 minute from current time

I need to get the time at the previous 5 minute interval. For example, suppose the time is

03-04-2024 07:16 I want 03-04-2024 07:15
03-04-2024 07:24 I want 03-04-2024 07:20
03-04-2024 07:45 I want 03-04-2024 07:45

I am getting the current time like this

DateTime now = DateTime.timestamp();

But need to work it back. Do I just need to loop by removing a minute until a 0 or 5?

>Solution :

I believe this should work:

now = now.subtract(Duration(minutes: now.minute.remainder(5)));
