# mediaDuration method

String mediaDuration({

1. bool addSpacing = true,

})

Formats the media duration into a human-readable string.

- Converts total seconds into hours, minutes, and seconds.
- Displays hours only if the duration is 1 hour or more.
- Supports optional spacing between time units.

Example outputs:

- `45` seconds → `"00:45"`
- `125` seconds → `"02:05"`
- `4000` seconds → `"01:06:40"`

`addSpacing` If `true`, adds spaces around colons (`"01 : 06 : 40"`). If `false`, returns a compact format (`"01:06:40"`).

Returns a formatted string representing the media duration.

## Implementation

    String mediaDuration({bool addSpacing = true}) {
      String hours = (this ~/ 3600).toTimeUnit();
      String minutes = ((this % 3600) ~/ 60).toTimeUnit();
      String seconds = (this % 60).toTimeUnit();

      String separator = addSpacing ? " : " : ":";

      return hours != "00" ? "$hours$separator$minutes$separator$seconds" : "$minutes$separator$seconds";
    }
