How do I handle heavy computations without freezing the UI?

This skill provides implementation patterns for using Dart Isolates and the compute function to move CPU-intensive tasks off the main thread.

Can it assist in finding memory leaks?

Yes, it guides you through proper disposal patterns for controllers, timers, and stream subscriptions, and explains how to use Flutter DevTools to identify retained objects.

How does this skill help with Flutter jank?

It provides strategies to minimize widget rebuilds, isolate expensive paint operations with RepaintBoundary, and optimize list rendering to ensure the UI thread stays under the 16ms frame budget.

Does it support high-performance image handling?

Absolutely. It covers image caching strategies, precaching assets, and optimizing memory usage for large images using memCacheWidth and height properties.
