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 `Provider` package

What is the `Provider` in Flutter? 
The `Provider` is a Flutter package. It’s a wrapper around the `InheritedWidget`.

Before we proceed, we must add the dependency on the `provider` to the `pubspec.yaml` file.

It looks like this:

dependencies:
  flutter:
    sdk: flutter
  provider:

Now you are set to use the `provider` to manage a state in your app.

What is a state? The state is something that exists in memory. When the app is running, in most cases, we will try to manage the state. The `Provider` helps you to do that.

The state itself is critical, while efficiently managing it is essential too. 

That's because managing state is crucial to building any complex app that handles multiple screens, different variables, and user sessions. Hence, you should plan it.

Flutter creates a deep and nested widget tree. To manage a state at the lowest bottom, we cannot rebuild every top widget. That is wasteful memory consumption. 

So, how can we solve this problem? The `Provider` package in Flutter is the answer!

Now let us do some coding together. Our goal is to understand the main concept of Flutter `Provider`.

Using `ChangeNotifierProvider` is one solution. It comes from the provider package, and it provides an instance of a `ChangeNotifier` to the widgets. So now Flutter has in-built mechanisms for widgets to provide data and services to their distant descendants.

Widget is very powerful. `ChangeNotifierProvider` uses that power to notify the listeners.

How does it do that?

By making it possible to place it on top of our widget tree.

Learn what a provider library is and how you can use the "Provider.of<T>" method.
