Dart Getter Method

Dart Getter Method

In this tutorial, we will learn about the Dart getter method. The getter method reads the variable’s value or retrieves the object’s property.

Syntax

We can define the getters method by using the get keyword with no parameter and valid return type.

The general syntax to define a getter method is as follows:

return_type get getter_name {
    return field_name;
}

Example

Let’s define a getter method in the following example:

class Car {
    String make;
    String model;
    int year;
    String color;

  //Getter method
String get carColor {
       return color;
}

// Constructor
Car({required this.make, required this.model, required this.year, required this.color});
}

// main method
void main(){
   Car car=
   Car(make:”Toyota”,model:”Sedan”,year:2018,color:”Blue”);
   print(“Car company : ${car.make}”);
   print(“Car model : ${car.model}”);
   print(“Car color : ” + car.carColor);
}
