问题 Hi I'm receiving a string with a date format yyyy-MM-dd , but I want to compare it with a format dd-MM-yyyy in case it is not the same, sure is not, I want to convert it, the problem for me it's not to convert, it's to compare both formats... so I imagine maybe it's something like this var dt = obj.date; //this a string if (dt.formatDateorsomethingIguess == "dd/MM/yyyy") //this is the part I'm asking for { usedt(dt); } else { DateTime dt_format = DateTime.ParseExact(dt.Trim(), "dd-MM-yyyy",

问题 I'm running this on flutter, but I guess this could be a more general issue. I am saving a DateTime in the preferences. I want to be able to then tell if DateTime.now() is on at least a day after the last saved DateTime, i.e. (pseudocode) lastDailyCheck = 2020.04.10 now = 2020.04.11 => now is a day after the lastDailyCheck.
