you defined a list that it is an empty list

You Have To validate TextFormField before Submitting the value. If the Field value is empty you have to add the default value by checking the field Controller. On Other Words, if the field is not mandatory then the field must be submitted by some default value in that way you can get rid of Null Saftey Errors.
