Cloud support DateTime.isLeapYear

[wangbo4020]

Like this

extension DateTimeExtension on DateTime {

  bool get isLeapYear => year % 400 == 0 || year % 100 != 0 && year % 4 == 0;

  int get daysInMonth => _calcDaysInMonth();

  int _calcDaysInMonth() {
    switch (month) {
      case DateTime.january:
      case DateTime.march:
      case DateTime.may:
      case DateTime.july:
      case DateTime.august:
      case DateTime.october:
      case DateTime.december:
        return 31;
      case DateTime.february:
        return isLeapYear ? 29 : 28;
      case DateTime.april:
      case DateTime.june:
      case DateTime.september:
      case DateTime.november:
      default:
        return 30;
    }
  }
}
