FormBuilderDateTimePicker onChanged callback returns incorrect date

Bug

When using the callback onChanged with FormBuilderDateTimePicker it returns dates from 1970, rather than the date the user selected!

Steps to reproduce

• Create a form
• Add this form and use it

 FormBuilderDateTimePicker(
                initialDate: DateTime.now(),
                onChanged: (DateTime d){
                  print("SELECTED DATETIME: $d");
                },
                attribute: "startTime",
                inputType: InputType.both,
                format: DateFormat("EEEE MMM d kk:mm"),
                decoration:
                    InputDecoration(labelText: "Enter a time and view logs"),
              ),

Hi @opringle,
Thanks for bringing this to my attention. I'll test and work on a fix ASAP.

Seems this bug is caused by the underlying library, datetime_picker_formfield, which when submitting it tries to parse the string in the TextField back to a DateTime. But since your DateFormat lacks the year field, it is substituted by 1970.

This issue has already been reported in the library.

I'll try to do a workaround for the benefit of our library.

Hi @opringle,
Kindly check out v3.6.0. It contains a fix for this.
