this.name = inputName;
this.age = inputAge;
}//Person()
}//Person
void main() {
var p1 = Person("Rizwan", 34);
var p2 = Person("Ali", 32);
print(p1.name); //Rizwan
print(p1.age); //34
print(p2.name); //Ali

}
In this constructor we are using positional arguments i.e, inputName and inputAge instead of named arguments.
