label method

String label({
  1. Duration? reference,
})

Returns a String representation of Duration.

Implementation

String label({Duration? reference}) {
  reference ??= this;
  reference = reference.abs();

  if (isNegative) {
    return abs().label(reference: reference);
  }

  if (reference > const Duration(days: 1)) {
    final days = inDays.toString().padLeft(3, '0');
    final hours = (inHours - (inDays * 24)).toString().padLeft(2, '0');
    final minutes = (inMinutes - (inHours * 60)).toString().padLeft(2, '0');
    final seconds = (inSeconds - (inMinutes * 60)).toString().padLeft(2, '0');
    return '$days:$hours:$minutes:$seconds';
  } else if (reference > const Duration(hours: 1)) {
    final hours = inHours.toString().padLeft(2, '0');
    final minutes = (inMinutes - (inHours * 60)).toString().padLeft(2, '0');
    final seconds = (inSeconds - (inMinutes * 60)).toString().padLeft(2, '0');
    return '$hours:$minutes:$seconds';
  } else {
    final minutes = inMinutes.toString().padLeft(2, '0');
    final seconds = (inSeconds - (inMinutes * 60)).toString().padLeft(2, '0');
    return '$minutes:$seconds';
  }
