How to manage state in Flutter using Provider

There are several ways to manage state in Flutter. My personal favorite is a package called Provider. It allows you to inject the state into a widget and its children. This video will explain how to selectively rebuild widgets in a widget tree using the Provider, Consumer, and Selector classes. There is a lot more that isn't covered in this video, but this should get you comfortable with basics of the Provider package.
