Flutter SDK is an excellent tool for developing cross-platform applications from a single codebase. So, it's no surprise that many professionals and learners have decided to gain mastery over Flutter concepts.

One such concept is state management, and many, despite having intermediate-to-advanced proficiency in Flutter, still struggle with this concept. This course will help you learn and master the best practices for state management in Flutter.

You will learn to use the two best Flutter libraries, Riverpod and Provider, for state management. You will even learn about reducing widget rebuilds by managing their state.

Master State Management in Flutter

## Problem statement

Build a small quiz app where pressing buttons will take you to the next question. 

The main challenge is to build the app with a stateful widget and increment the list's index that consists of the questions. 

Another challenge is to separate the question and answer widgets into two files and pass them through callbacks. Also, map the list so it returns our desired solution. Finally, display if an answer was correct or wrong. 

In this challenge, write all of the code in all three files yourself.

## Expected output

The following image is a sample output. Your app’s output can be slightly different based on your approach, but it should satisfy the entire problem statement.
