✐ Examples

1 Calculating seconds from days and hours

In this example,

  1. We create a Duration object duration with 2 days and 3 hours.
  2. We get the total seconds using the inSeconds property.
  3. We then print the total seconds to standard output.

Dart Program

void main() {
  Duration duration = Duration(days: 2, hours: 3);
  int seconds = duration.inSeconds;
  print('Total seconds: $seconds');
}

Output

Total seconds: 183600

2 Calculating seconds from hours and minutes

In this example,

  1. We create a Duration object duration with 10 hours and 30 minutes.
  2. We get the total seconds using the inSeconds property.
  3. We then print the total seconds to standard output.

Dart Program

void main() {
  Duration duration = Duration(hours: 10, minutes: 30);
  int seconds = duration.inSeconds;
  print('Total seconds: $seconds');
}

Output

Total seconds: 37800

3 Calculating seconds from minutes

In this example,

  1. We create a Duration object duration with 150 minutes.
  2. We get the total seconds using the inSeconds property.
  3. We then print the total seconds to standard output.

Dart Program

void main() {
  Duration duration = Duration(minutes: 150);
  int seconds = duration.inSeconds;
  print('Total seconds: $seconds');
}

Output

Total seconds: 9000
