Pre-calculation example
void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id =1;
employee1.name ="John Doe";
employee1.position ="CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary ;
// You can remove the return type from setter method
void set empsalary(int dayworked) {
this.salary = dayworked*20;
}
int get empsalary{
return this.salary;
}
}
void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id =1;
employee1.name ="John Doe";
employee1.position ="CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary ;
// You can remove the return type from setter method
void set empsalary(int dayworked) {
salary = dayworked*20;
}
int get empsalary{
return salary;
}
}void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id =1;
employee1.name ="John Doe";
employee1.position ="CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary ;
// You can remove the return type from setter method
void set empsalary(int dayworked) => this.salary = dayworked*20;
int get empsalary => this.salary;
}void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id =1;
employee1.name ="John Doe";
employee1.position ="CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary ;
// You can remove the return type from setter method
void set empsalary(int dayworked) => salary = dayworked*20;
int get empsalary => salary;
}I mentioned you can remove the return type from setter method without any problem, but
you can actually also remove return type from getter method also without any problem . Dart compiler can assume the return type
void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id = 1;
employee1.name = "John Doe";
employee1.position = "CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary;
// You can remove the return type from setter method
set empsalary(int dayworked) => salary = dayworked * 20;
// You can remove the return type from getter method also
get empsalary => salary;
}
Pre checking example
void main() {
// Custom Getters & Setters
var employee1 = Employee(); // Creating employee1 object
employee1.id =1;
employee1.name ="John Doe";
employee1.position ="CTO";
employee1.empsalary = 30; // Calling the custom setter method
print(employee1.empsalary); // Calling the custom getter method
}
class Employee {
int id;
String name;
String position;
int salary ;
// You can remove the return type from setter method
void set empsalary(int dayworked) {
if(dayworked<=31)
{
this.salary = dayworked*20;
}
else{
this.salary = -1;
}
}
int get empsalary{
return this.salary;
}
}You can also use custom getters and setters as an "alias" for the original instance variables.
