Flutter 安全存储平台异常
Flutter Secure Storage Platform Exception
我正在使用 flutter 安全存储 (^5.0.2) 来保存令牌，但是在模拟器上调用 storage.write() 时出现以下错误（我正在使用 Pixel 5 API 30) 而当我在我的物理设备 (Honor 8x) 上使用它时它运行良好:
PlatformException (PlatformException(Exception encountered, write, java.lang.NullPointerException: Attempt to invoke interface method 'byte[] com.it_nomads.fluttersecurestorage.ciphers.StorageCipher.encrypt(byte[])' on a null object reference

这是调试的输出：

我不知道它是否相关，但我的代码中有 min Sdk 19，因为一些包需要这个版本。
我需要这个来启动我的物理设备和 Vscode 上的模拟器，在我的应用程序中使用两个不同的帐户（一个管理员和一个用户）来检查通知从一个到另一个的传输，如果另一个实现这一目标的方法存在，我也会知道。

如果它对某人有帮助，我通过在设备参数中清除模拟器上应用程序的数据和缓存来修复它。
