💡 What: Added windowing props (initialNumToRender, windowSize, maxToRenderPerBatch, removeClippedSubviews) to FlatList components across three screens. Fixed React.memo by ensuring list item callbacks are wrapped in useCallback and passed properly to prevent unnecessary re-renders.
🎯 Why: Inline arrow functions in renderItem were defeating React.memo by creating new references on every render, causing all items to re-render. Long lists were also not utilizing windowing optimizations.
📊 Impact: Eliminates unnecessary list item re-renders and reduces memory usage/render time for large lists, making screen navigation and filtering noticeably smoother.
🔬 Measurement: Profile the React tree during typing in search fields or deleting items; component re-renders for unchanged list rows are now bypassed.
