Date string not recognized as valid DateTime-CodePudding

I am storing a date string in SharedPreferences as 2022-9-14 19:34, but this is not recognized as DateTime when using

 DateTime dt1 = DateTime.parse(_inicio);
        print("fecha······· ${(dt1)}");

I am getting the following error:

Invalid date format
2022-9-14 19:34

What I need is to show the date string as 14-09-2022 19:34

EDIT

The date string is saved as follows:

var hoy = DateTime.now();
                        var ano = hoy.year.toString();
                        var mes = hoy.month.toString();
                        var dia = hoy.day.toString();
                        var turno = "";
                        var fechaHora = ano "-" mes "-" dia " " _timeOfDay.format(context).toString();

And _timeOfDay is the picked time from TimePicker.

CodePudding user response：

2022-09-14 19:34 is one of the valid case. So you need to add zeros where there is a single digit (month in this case)

But a better solution would be to store DateTime.now().toString() directly in shared-preferences. You could also use a package like intl to format the date in your choice of format.

Since you're using time as well from timepicker, you could use DateTime constructor will all 5 values like this:

new DateTime(year, month, date, hour, minute).toString();
