Could you explain what is meant by object-oriented programming?

Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which combine data and methods to operate on that data. The main principles of OOP:

• Encapsulation — combining data and methods into a single object, hiding internal implementation.
• Inheritance — the ability to create new classes based on existing ones, inheriting their properties and behaviors.
• Polymorphism — the ability of objects of different classes to respond to the same messages (methods) in different ways.
• Abstraction — highlighting the essential characteristics of an object, hiding implementation details.

For example, in Flutter (Dart), you can define a class Car with fields and methods, and then create objects of this class to model specific cars.
