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

Create a Flutter application to manage the state through the `Provider`. Don’t use the stateful widget.

The first challenge is to create a counter where you can increment numbers by pressing the button and changing the state. 

The second challenge is to test whether a text message starts with the letter “s” or not.

As a head start, we have already completed  the model class for you. You only need to make changes to the `controller.dart` file.

## 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.
