DateTimeFormField class
A FormField that contains a DateTimeField.
This is a convenience widget that wraps a DateTimeField widget in a FormField.
A Form ancestor is not required. The Form simply makes it easier to save, reset, or validate multiple fields at once. To use without a Form, pass a GlobalKey to the constructor and use GlobalKey.currentState to save or reset the form field.
