I have been working on my quiz app and learned the four pillars of oop in Dart:- abstraction, encapsulation, inheritance, and polymorphism.
Abstraction:- made different classes to manage questions and answers,
Encapsulation:- made the question list private so it can't be changed outside the question class. (used underscore)
Inheritance:- (extends keyword)
Polymorphism:- (@override and super keyword)
Completed the quiz app.
