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


## What is the `StateNotifier`?

`StateNotifierProvider` is just another `Provider` variant in `Riverpod` to manage state in Flutter. However, there is a remarkable difference with `ChangeNotifierProvider`.

## What is the `StateNotifierProvider`?
The `StateNotifierProvider` does not use `notifyListener()` anymore as it does not extend the data model with `ChangeNotifier`. However, it depends on `StateNotifier`, a Flutter independent mutable state change mechanism that has similarities with `ChangeNotifier` or `ValueNotifier`.

We'll come to that point and discuss the core concepts in detail in the latter part of this lesson.
