Flutter 时间处理合集

时间戳转成中文格式的时间

String formatCNDate(int dateValue, {bool withDetail:true}) {
  /// dateValue: 需要格式的时间戳， withDetail: 是否返回时分秒
  if(dateValue != null) {
    var date = new DateTime.fromMillisecondsSinceEpoch(dateValue);
    if(withDetail) {
      return '${date.year}年${date.month}月${date.day}日 ${date.hour.toString().padLeft(2, "0")}:${date.minute.toString().padLeft(2, "0")}:${date.second.toString().padLeft(2, "0")}';
    }else {
      return '${date.year}年${date.month}月${date.day}日';
    }
  }else {
    return '';
  }
}

音视频播放时间格式化

String formatSeconds(int seconds) {
  String toDigits(int n) => n.toString().padLeft(2, "0");
  Duration duration = Duration(seconds: seconds)
  String toDigitMinutes = twDigits(duration.inMinutes);
  String toDigitSeconds = toDigits(duration.inSeconds.remainder(60));
  return "$toDigitMinutes:$toDigitSeconds";
}

计算时间差

String workDuration (int endValue) {
  /// endValue: 结束时间戳
  var endTime = new DateTime.fromMillisecondsSinceEpoch(endValue);
  var nowTime = new DateTime.now();
  if(nowTime.isBefore(endTime)) {
    var diff = nowTime.difference(endTime);
    var diffTime = diff.toString().split('.')[0];
    return diffTime.replaceAll('-', '');
  }else {
    return '00:00:00';
  }
}
