Dart Setter method

In this tutorial, we will learn about the Dart Setter method, which sets or initializes the values of the fields. We can declare the setter method using the set keyword with one parameter.

Syntax

The general syntax for the setter method is as follows:

void set setter_name(data_type param) {

this.field_name = param;

}

Example

class Book {
 late String title;
 late String author;
 late double price;

 // setter methods
 void set book_title(String title) {
 this.title = title;
 }

 void set book_author(String author) {
 this.author = author;
 }

 void set book_price(double p) {
 this.price = p;
 }

 // getter methods
 String get book_author {
 return author;
 }

 String get book_title {
 return title;
 }

 double get book_price {
 return price;
 }
}


 void main() {
// create book object
 Book bObj = new Book();
 bObj.book_author = "Sears & Zemansky";
 bObj.book_title = "University Physics";
 bObj.book_price = 99.99;

// print book object
 print("Book Author: " + bObj.book_author);
 print("Book Title : " + bObj.book_title);
 print("Book Price :\$ " + bObj.book_price.toString());
 }
