⚡ Bolt: Memoize flight list filtering#3
Conversation
Wrap the `currentData` array calculation in a `useMemo` hook in `FlightScreen.tsx`. This prevents O(N) recalculations on unrelated state updates. Co-authored-by: TargetMisser <52361977+TargetMisser@users.noreply.github.com>

💡 What: Wrapped the
currentDataarray filtering logic in auseMemohook with strict dependencies inFlightScreen.tsx.🎯 Why: The flight list can be large. Previously, changing unrelated state (like toggling notifications or opening a modal) would trigger a synchronous re-filter of the entire list on every render, causing frame drops on the JS thread.
📊 Impact: Eliminates O(N) list recalculations during unrelated UI interactions, significantly reducing JS thread workload and preventing dropped frames when interacting with the screen.
🔬 Measurement: Profile the React Native JS thread using React DevTools Profiler while toggling the notifications button with a large list of flights; observe the reduction in render duration.
