Defining Dart Classes
Dart classes use class with properties and methods.
Introduction to Dart Classes
In Dart, a class is a blueprint for creating objects. A class encapsulates data for the object and methods to operate on that data. Classes in Dart are defined using the class keyword followed by the class name. This tutorial will guide you through the basics of creating and using classes in Dart.
Defining a Class
To define a class in Dart, you use the class keyword followed by the class name. Inside the curly braces, you can define properties and methods.
Creating an Instance of a Class
Once a class is defined, you can create an instance (or object) of that class. An instance is an individual object created using the class blueprint.
Properties in Dart Classes
Properties in Dart classes are variables that hold data associated with a class. You can define properties in a class without initializing them immediately, as seen in the Car class example. They can be accessed and modified using dot notation on an instance of the class.
Methods in Dart Classes
Methods are functions defined within a class that can operate on the properties of the class. They are used to perform actions or calculations using the class data. In our Car class, the displayInfo method prints the details of the car to the console.
Conclusion
Understanding classes in Dart is fundamental for object-oriented programming. Classes allow you to model real-world entities in your code, encapsulating related properties and behaviors. In the next post, we will explore constructors, which provide a way to initialize objects of a class in Dart.
