Can this skill help prevent app crashes on low-memory devices?

Absolutely. It details memory management techniques, including the proper disposal of controllers and the use of WeakReferences for callbacks.

Is it compatible with state management libraries like GetX?

Yes, it includes specific patterns for GetX controller lifecycles, lazy loading, and reactive state optimization.

How does this skill help achieve 60 FPS in Flutter?

It provides implementation patterns for minimizing widget rebuilds and using const constructors to ensure rendering remains under the 16ms per frame threshold.

Does it include guidance for handling large lists?

Yes, it covers efficient rendering using ListView.builder, cacheExtent optimization, and pagination patterns for infinite scrolling.

Does it cover image rendering optimization?

Yes, the skill provides best practices for image caching, resizing assets for memory efficiency, and precaching images to improve UX.
