toDisplay method

Implementation

String toDisplay() {
  String twoDigits(int n) => n.toString().padLeft(2, "0");
  String twoDigitHours = twoDigits(inHours);
  String twoDigitMinutes =
      twoDigits(inMinutes.remainder(Duration.minutesPerHour));
  String twoDigitSeconds =
      twoDigits(inSeconds.remainder(Duration.secondsPerMinute));
  return "$twoDigitHours:$twoDigitMinutes:$twoDigitSeconds";
}
