Does Flutter Secure Storage persist once the app closes?

Question

I tried to store usernames and passwords after someone logged in successfully with Flutter Secure Storage, but I wasn't able to read the keys. Is this expected behavior or am I doing something wrong?

Answer 1

It is expected behavior that data written in secure storage persists after app is closed. Data is written in KeyStore and KeyChain on Android and iOS, respectively.

Answer 2

It does. You'll have to share code so we can see what you're doing wrong. In the mean there is also another way as recommended by Flutter examples.

I've had a great experience using the SharedPreferences plugin. It's easy to asign key-value pairs and retrieve them.
