addHours method
Adds a certain amount of hours to this date and returns a new DateTime instance.
Example:
DateTime currentDate = DateTime(2022, 1, 8, 12, 0);
DateTime futureDate = currentDate.addHours(3);
print(futureDate); // 2022-01-08 15:00:00.000
The addHours
method creates a new DateTime instance by adding the specified
number of hours to the original date. The date components (year, month, day)
remain unchanged.
Implementation
DateTime addHours(int amount) => DateTime(
year,
month,
day,
hour + amount,
minute,
second,
millisecond,
microsecond,
);
