How to make a field not required?
I know that I can make a field required using something like below statement:
formFields.setFieldProperty(field, "setfflags", PdfFormField.FF_REQUIRED, null);
Is there anything similar to make an existing field not required

By default, the "required field" flag is not set when creating a form field. As you indicate in your question, you can use the setFieldProperty()
method to set this flag:
formFields.setFieldProperty(field, "setfflags", PdfFormField.FF_REQUIRED, null);
Based on your question, I assume that you have an existing PDF where you have fields for which this flag is already set. You can removed this flag (remove the bit from the bit set), by changing "setfflags"
into "clrfflags"
:
formFields.setFieldProperty(field, "clrfflags", PdfFormField.FF_REQUIRED, null);
In this context clr
stands for clear and fflags
stands for field flags (not to be confused with clrflags
which will clear flags in the widget annotation).
