[Flutter] Flutter(dart) error: The argument type can't be assigned to the parameter type...

In the new version of Flutter, I encountered an error as follows.

error: The argument type 'List?' can't be assigned to the parameter type 'dynamic Function(List?)'. (argument_type_not_assignable at [temel_widget] lib\screens\student_add.dart:14)

class StudentAdd extends StatefulWidget {
//Student addStudent = Student.withId(0, "", "", 0);
List<Student>? students;
StudentAdd(List<Student>? students) {
this.students = students;
}
@override
State<StatefulWidget> createState() {
return _StudentAddState(students); **This here error message**
}
}


class _StudentAddState extends State with StudentValidationMixin {
//Student addStudent = Student.withId(0, "", "", 0);

List<Student>? students=[];
var student = Student.withoutInfo();
var formKey = GlobalKey<FormState>();

_StudentAddState(StudentAdd(List<Student>? students)) {
this.students = students;
}
