The app needs to securely store API keys and sensitive portfolio data. How would you implement encryption and secure storage in Flutter? |

Use flutter_secure_storage for sensitive data with platform-specific keychains. Implement AES encryption via pointycastle for additional data protection. Use biometric authentication via local_auth for app access. Never store plaintext keys and implement certificate pinning for API calls. |
