In this chapter, we will save the user's preference for the music volume, so let's add the library for persisting this value in our game:

1. Open the pubspec.yaml file and add the following dependency:

   shared_preferences: ^2.0.15

2. Save the file and allow pub get to download this dependency and validate the assets:

   flutter pub get

In the next section, we will discuss the final code we need to add to the game to wrap things up, including the game screens and navigation.
