Does it support image optimization?

The skill includes patterns for integrating react-native-fast-image for superior caching and preloading strategies to prevent image-related UI flickering.

How does this skill improve list performance?

It implements virtualization best practices like getItemLayout, initialNumToRender, and removeClippedSubviews to handle large datasets efficiently without consuming excessive memory.

What profiling tools does this skill help with?

It guides developers through using the React DevTools Profiler and the PerformanceObserver API to measure component render durations and identify bottlenecks.

Can it help reduce my app's bundle size?

Yes, it provides specific configurations for enabling the Hermes engine, ProGuard for Android, and implementing code splitting to minimize the final binary size.
