Performance

Push your Flutter app to the absolute limit. Learn how to achieve zero-overhead native communication using FFI and Rust, and when you should (and shouldn’t) use it.

Stop Out-Of-Memory (OOM) crashes and reduce your download size. Learn the critical rules of Image Caching, hunting Memory Leaks, and analyzing your final build size.

Stop freezing your app during heavy data processing. Learn the difference between async/await and true concurrency, and how to use Isolate.run() to keep your UI silky smooth.

Keep your 60 FPS target by controlling widget rebuilds. Learn the magic of const, why you should stop using helper methods for UI, and how to use RepaintBoundary and modern state management.

Measure first, optimize later. Stop guessing why your Flutter banking app is lagging and learn how to use DevTools, Profile Mode, and the Performance Overlay to find the real bottlenecks.
