humanReadable function

String humanReadable(Duration duration)

Returns a human readable string for a duration.

Handles durations that span up to hours - this will not be a good fit for durations that are longer than days.

Always attempts 2 'levels' of precision. Will show hours/minutes, minutes/seconds, seconds/tenths of a second, or milliseconds depending on the largest level that needs to be displayed.

Implementation

String humanReadable(Duration duration) {
  if (duration < const Duration(seconds: 1)) {
    return '${duration.inMilliseconds}ms';
  }
  if (duration < const Duration(minutes: 1)) {
    return '${(duration.inMilliseconds / 1000.0).toStringAsFixed(1)}s';
  }
  if (duration < const Duration(hours: 1)) {
    final minutes = duration.inMinutes;
    final remaining = duration - Duration(minutes: minutes);
    return '${minutes}m ${remaining.inSeconds}s';
  }
  final hours = duration.inHours;
  final remaining = duration - Duration(hours: hours);
  return '${hours}h ${remaining.inMinutes}m';
}
