Summary

In this chapter, you saw how to use a Stream in a Flutter app, read and write data to streams, build reactive user interfaces based on Streams, and implement the BLoC state management pattern.

You used StreamControllers and their Streams and Sinks. You learned how to subscribe to stream events, allow multiple stream subscriptions, and use the StreamBuilder widget to create reactive user interfaces.

You saw how to handle data and errors generated by streams, ensuring your app can manage different outcomes gracefully.

Now you can use Streams and BLoCs in your Flutter applications; this can help you create more robust, maintainable, and scalable apps that respond seamlessly to changing data and user interactions.
