In Dart, you can use the DateTime class to work with dates and times. Here are some examples of how to use DateTime:
1. Create a DateTime object representing the current date and time:
DateTime now = DateTime.now();
2. Create a DateTime object for a specific date and time:
DateTime myBirthday = DateTime(1990, 6, 2, 12);
3. Convert a DateTime object to a string representation:
DateTime now = DateTime.now();
String dateString = now.toString();
print(dateString); // Output: 2022-08-23 21:45:00.123456
4. Get the year, month, day, hour, minute, or second from a DateTime object:
DateTime now = DateTime.now();
int year = now.year;
int month = now.month;
int day = now.day;
int hour = now.hour;
int minute = now.minute;
int second = now.second;
5. Perform arithmetic on DateTime objects:
DateTime now = DateTime.now();
DateTime tomorrow = now.add(Duration(days: 1));
DateTime yesterday = now.subtract(Duration(days: 1));
6. Compare DateTime objects:
DateTime now = DateTime.now();
DateTime later = DateTime.now().add(Duration(hours: 1));
bool isBefore = now.isBefore(later);
bool isAfter = now.isAfter(later);
These are just some of the ways you can use DateTime. There are many more methods and properties available on the DateTime class that you can use to work with dates and times in your Dart code.
