Understanding Classes and Objects in Dart Programming

The Role of Classes in Programming

• Classes are blueprints for creating objects.
• They define the structure and behavior of objects.
• Classes encapsulate data (attributes) and methods (functions) that operate on that data.
• A class serves as a template for creating multiple objects of the same type.

Creating Classes in Dart

• Classes can be created directly in a main program file.
• Classes can be created in separate files and imported into a main program file.
• A class definition begins with the keyword class followed by the class name.

The Purpose of an Object

• An object is an instance of a class.
• It represents a real-world entity, such as a person, car, or bank account.
• Each object has its own unique set of data and behavior.

The Ignition Point of a Dart Program

• The starting point of any Dart program is the main() function.

Why Objects in Object-Oriented Programming

• Objects allow for code reusability and organization.
• They help represent real-world entities in a program.
• They provide a modular approach to programming.
• Objects promote data hiding and encapsulation.
