A drag-and-drop-enabled FlatList component for React Native

import { useRef, useCallback } from "react";

// Utility hook that returns a function that never has stale dependencies, but
// without changing identity, as a useCallback with dep array would.
// Useful for functions that depend on external state, but
// should not trigger effects when that external state changes.
