I am currently working on a Doctor Appointment booking application using FlutterFirebase, I am facing a problem i.e I am unable to generate my own TimeStamp from the Selected Date and Time of the patient. The reason for the custom timestamp is that, so the Doctor can view the appointments according to the Date and Time which comes first. If I use the normal TimeStamp using DateTime.now() it would not function as I wished. So help me to generate a custom timestamp using my selected date and selected time. Also providing the code for reference.
