Formatting a Duration like HH:mm:ss

Question

Is there a good way to format a Duration in something like hh:mm:ss, without having to deal with time zones?

I tried this:

DateTime durationDate = Da

Basen on @diegoveloper's answer, I made it an extension which is also extendible

extension DurationExtensions on Duration {
  /// Converts the duration into a readable string
  /// 05:15
  String toHoursMinutes() {
    String twoDigitMinutes = _toTwoDigits(this.inMinutes.remainder(60));
    return "${_toTwoDigits(this.inHours)}:$twoDigitMinutes";
  }

  /// Converts the duration into a readable string
  /// 05:15:35
  String toHoursMinutesSeconds() {
    String twoDigitMinutes = _toTwoDigits(this.inMinutes.remainder(60));
    String twoDigitSeconds = _toTwoDigits(this.inSeconds.remainder(60));
    return "${_toTwoDigits(this.inHours)}:$twoDigitMinutes:$twoDigitSeconds";
  }

  String _toTwoDigits(int n) {
    if (n >= 10) return "$n";
    return "0$n";
  }
}
