7. SongDuration

This function is used to format the song’s duration in milliseconds, but we’ll convert it into the more useful format 00:00. The format is a string 00:00 in this case. It returns — : — if the duration is nil; otherwise, it returns the duration in the supplied format.

String _formatDuration(Duration d) {

if (d == null) return "--:--";

int minute = d.inMinutes;

int second = (d.inSeconds > 60) ? (d.inSeconds % 60) : d.inSeconds;

String format = ((minute < 10) ? "0$minute" : "$minute") +

":" +

((second < 10) ? "0$second" : "$second");

return format;

}
