showDateDialog static method

void showDateDialog(BuildContext context, { DateTime? startDate, DateTime? endDate, bool onClickOutSide = false, dynamic callBack(DateTime startTime, DateTime endTime)?, dynamic closeCallBack()?, double? aspectRatio, bool? allowSameDate = true, })

startDate 默认选中日历的开始日期 endDate 默认选中日历的结束日期 onClickOutSide 点击非日历区域是否关闭 Function 选择日期后的回调 aspectRatio 添加宽高比，设置的calendarHeight将失效。
