## 2024-04-13 - Missing React.memo for FlatList Items
**Learning:** The React Native FlatList components in this codebase frequently render unmemoized inline items (like `ContactRow`, `PasswordRow`, etc.), causing unnecessary re-renders of the entire list when individual state changes.
**Action:** Always wrap long list item components in `React.memo()` to prevent cascading re-renders and improve FlatList scrolling performance.
## 2024-04-19 - Fix React.memo and list rendering
**Learning:** Inline callback functions and missing useCallback defeat React.memo's shallow comparison in list rendering, leading to unnecessary re-renders of all list items.
**Action:** Always wrap callback props for list items in useCallback and pass item IDs instead of using inline arrow functions in renderItem. Also add windowing props to FlatList for large lists.
