[4] The “Flutter Favorite” Provider package makes state management “easier.” https://pub.dev/packages/provider

SOURCES
A good description of Imperative versus Reactive/Declarative programming in Flutter. https://www.dhiwise.com/post/declarative-ui-vs-imperative-ui-in-flutter-development

For an architectural overview of Flutter, check out this resource: https://docs.flutter.dev/resources/architectural-overview

For getting started with Flutter, I found this helpful even if you are not a React Native developer or a JavaScript programmer. https://docs.flutter.dev/get-started/flutter-for/react-native-devs

Another great place to start with Flutter can be found here: https://www.youtube.com/watch?v=xWV71C2kp38&list=PLjxrf2q8roU3wk7CDw4RfV3mEwOJbjx1k&index=4

This is a good resource of the Flutter design team’s perspective on state management. https://docs.flutter.dev/data-and-backend/state-mgmt/intro

There are scores of options of outside paradigms of state management here: https://docs.flutter.dev/data-and-backend/state-mgmt/options

For a fairly clear introduction to state management with Provider, this is fairly clear: https://www.dhiwise.com/post/achieving-optimal-performance-with-flutter-provider-state-management
