We will change this example to propagate those same dependencies using InheritedWidget rather than using property forwarding. Then, we will refactor that same example to use the Provider package, which is endorsed by the Flutter community and Google as a pragmatic solution to dependency injection and state management.

After downloading the initial application from GitHub, we can start by moving into its root directory and running the flutter pub get command...
