必须首先将字符串解析为DateTime，将错误行更改为：
DateTimedate1=DateTime.parse("2021-01-01");print(date1);//2021-01-0100:00:00.000 日期转指定格式的字符串时间 //获取当前的时间DateTimedate=DateTime.now();//组合Stringtimestamp="${date.year.toString()}-${date.month.toString().padLeft(2,'0')}-${date.day.toString().padLeft(2,'0')}...
但是要计算最大值,我需要一个DateTime列表,但是sharedpref只能保存listString。因此,我需要将字符串列表转换为日期时间列表。 我尝试过,但是找不到解决方案 DateTime maxDate; List<String> stringList = []; List<DateTime> DateList= []; load_max_conso() async { SharedPreferences prefs = await ...
