I have these small lines:
Timestamp timestamp = document.get("timestamp"); DateTime time = timestamp.toDate(); time.add(const Duration(hours: 3)); print(time);
What can it be caused by?
If you check the documentation of the
add method you will see that it’s not a setter, rather it returns a new
DateTime so you need it to assign to a new value.
var threeHoursFromNow = time.add(const Duration(hours:3));
