How to securely store sensitive data in Flutter?
问题
我正在开发一个Flutter应用程序，需要存储敏感用户数据，如API密钥和访问令牌。我希望确保这些数据安全存储在设备上，以防止未经授权的访问。
有关在Flutter中安全存储敏感数据的最佳实践和推荐方法是什么？除了flutter_secure_storage之外，是否有任何内置的Flutter API或库可以帮助进行安全存储？我应该如何保护来自.env文件的敏感变量？
英文:
I’m developing a Flutter application that needs to store sensitive user data, such as API keys and access tokens. I want to ensure that this data is securely stored on the device to prevent unauthorized access.
What are the best practices and recommended approaches for securely storing sensitive data in Flutter? Are there any built-in Flutter APIs or libraries that can help with secure storage (besides flutter_secure_storage)? How should I protect sensitive variables from .env file?

我建议在Flutter中使用flutter_secure_storage来安全存储访问令牌。这是一个可靠的包，它会加密数据并将其存储在设备的安全存储中（在iOS上是钥匙串，而在Android上是密钥库）。它提供了诸如加密、与Flutter轻松集成以及平台无关的代码等优势。请记住仅存储必要的数据，定期更新依赖项，并实施诸如令牌过期和安全通信协议等额外的安全措施。
英文:
I would recommend using flutter_secure_storage for securely storing access tokens in Flutter. It's a reliable package that encrypts data and stores it in the device's secure storage (keychain on iOS, keystore on Android). It offers benefits like encryption, easy integration with Flutter, and platform-agnostic code. Remember to store only essential data, regularly update dependencies, and implement additional security measures like token expiration and secure communication protocols.
