Can you explain what is meant by the concept of abstraction in programming?

Abstraction in programming is the process of highlighting the essential characteristics of an object or system and hiding non-essential details. This allows working with objects at a higher level without delving into complex internal mechanisms.

For example, in Flutter, you can create an abstract class or interface that describes the behavior of a widget without revealing how its methods are implemented:

abstract class Animal {
  void makeSound();
}

class Dog extends Animal {
  @override
  void makeSound() {
    print('Woof');
  }
}

Here, Animal is an abstraction, and the concrete classes implement the details.
