✐ Examples

1 Calculating absolute value of a positive Duration

In this example,

  1. We create a Duration object duration1 with 2 days and 3 hours.
  2. We call the abs() method to get its absolute value as a new Duration object.
  3. We then print the absolute Duration 1 to standard output.

Dart Program

void main() {
  Duration duration1 = Duration(days: 2, hours: 3);
  Duration absDuration1 = duration1.abs();
  print('Absolute Duration 1: $absDuration1');
}

Output

Absolute Duration 1: 51:00:00.000000

2 Calculating absolute value of a negative Duration

In this example,

  1. We create a Duration object duration2 with -10 hours and 30 minutes.
  2. We call the abs() method to get its absolute value as a new Duration object.
  3. We then print the absolute Duration 2 to standard output.

Dart Program

void main() {
  Duration duration2 = Duration(hours: -10, minutes: 30);
  Duration absDuration2 = duration2.abs();
  print('Absolute Duration 2: $absDuration2');
}

Output

Absolute Duration 2: 9:30:00.000000

3 Calculating absolute value of a negative Duration in minutes

In this example,

  1. We create a Duration object duration3 with -150 minutes.
  2. We call the abs() method to get its absolute value as a new Duration object.
  3. We then print the absolute Duration 3 to standard output.

Dart Program

void main() {
  Duration duration3 = Duration(minutes: -150);
  Duration absDuration3 = duration3.abs();
  print('Absolute Duration 3: $absDuration3');
}

Output

Absolute Duration 3: 2:30:00.000000
