安卓卸载应用存储的信息会一并删除，ios不行，当app卸载后，重新安装依旧可以找到存储在钥匙串里的信息，请问怎么可以解决ios端的问题

[kinmonkey7]

static const _storage = FlutterSecureStorage( iOptions: IOSOptions( accessibility: KeychainAccessibility.unlocked_this_device, ), aOptions: AndroidOptions( encryptedSharedPreferences: true, ), );有没有好的方法可以解决ios的问题

应用运行时创建一个文件，把应用删除文件也会被删除，在每次运行时判断这个文件是否存在，不存在则是刚刚安装了应用，这时就可以把机密存储全部清除再继续应用。

@kinmonkey7 This is not a bug. If you want to delete the data after deleting the app, you should not use this package. It is implemented using Keychain on the iOS side, which is its feature.
