hourMinSec method

String hourMinSec(
  1. int time
)

获取剩余时间 时分秒： 12:03:01

Implementation

String hourMinSec(int time) {
  final residueTime = time.abs();
  final hour = residueTime / 60 ~/ 60;
  final min = ((residueTime / 60) % 60).toInt();
  final second = residueTime % 60;
  final h = hour.toString().padLeft(2, '0');
  final m = min.toString().padLeft(2, '0');
  final s = second.toString().padLeft(2, '0');
  return time > 0 ? '$h:$m:$s' : '-$h:$m:$s';
}
