Often times, you’ll define a class but you may need to make a slight alteration to a class for a specific situation. This is would result in you either copying and pasting the class to make your edits or you’d jury rig some solution that would increase the overall complexity of the class.

class Person {

String firstName;
String lastName;
Person(this.firstName, this.lastName);
String getFullName() => '$firstName $lastName';
class Student extends Person {

Student(this.firstName, this.lastName);
Student(String firstName, String lastName) : super(firstName, lastName);
Student(super.firstName, super.lastName) 
var student = Student('Ray', 'Wenderlich');
