addDays method
Adds a certain amount of days to this date and returns a new DateTime instance.
Example:
DateTime currentDate = DateTime(2022, 1, 8);
DateTime futureDate = currentDate.addDays(5);
print(futureDate); // 2022-01-13 00:00:00.000
The addDays
method creates a new DateTime instance by adding the specified
number of days to the original date. The time components (hour, minute, second,
millisecond, microsecond) remain unchanged.
Implementation
DateTime addDays(int amount) => DateTime(
year,
month,
day + amount,
hour,
minute,
second,
millisecond,
microsecond,
);
