I am currently architecting a complex enterprise application using Flutter and I'm torn between using BLoC and Riverpod. My main concern is preventing unnecessary widget rebuilds as the app scales to hundreds of screens. What are the best practices for state management in 2024 to ensure the UI stays responsive at 60fps even with heavy data streams?

When dealing with enterprise-scale Flutter apps, the choice between BLoC and Riverpod often boils down to team preference, but performance-wise, both are excellent if used correctly. In my experience with high-traffic apps in 2023, the key isn't just the library but the granularity of your state. Ensure you are using 'select' in Riverpod or 'buildWhen' in BLoC to filter rebuilds. Also, consider offloading heavy JSON parsing to a separate Isolate to keep the main thread free. This architecture has saved us from significant UI jank during complex data synchronization cycles.
Have you looked into the recent updates regarding the Impeller rendering engine? I’ve noticed that some "state" issues are actually just shader compilation jank which Impeller fixes. Are you targeting iOS primarily where this is more noticeable?
I always recommend Riverpod for its compile-time safety. It makes debugging state much easier than BLoC's event-based stream approach, especially for new developers joining the team.
I agree with Jessica! Riverpod's lack of dependency on the BuildContext makes it far more flexible for global state, and Sarah's advice on using 'select' is the gold standard for performance.
David, that is a great point! We are targeting both iOS and Android. While Impeller helps with the rendering layer, my concern is still at the logic layer. Even with a fast engine, a poorly optimized Riverpod provider can trigger 50+ widget rebuilds if the state object is too "chunky." I’m trying to find that sweet spot between modularity and ease of maintenance for the dev team.
