i dont understand why should we use constructor? i mean if you didnt put the constructor, i still works way the same right? just change the void display to

void display (){
print ("Name is $name");
print ("Age is $age");
}

class Patient {
String? name;
int? age;
String? disease;

Patient(String name, int age, String disease) {
this.name = name;
this.age = age;
this.disease = disease;
}

void display() {
print("Name is $name");
print("age is $age");
print("Disease is $disease");
}
}

void main(List<String> args) {
Patient patient = Patient("vikram", 33, "typhoid");
patient.display();
}
