I'm looking for a way to add biometric authentication for reading values from **secure storage** (**KeyStore** and **KeyChain**) in the Flutter app.

I have found that this is possible to do in Android, I have not managed to make it work though:   

<https://labs.f-secure.com/blog/how-secure-is-your-android-keystore-authentication/>   

<https://riptutorial.com/android/example/29719/how-to-use-android-fingerprint-api-to-save-user-passwords>

In iOS:   

<https://developer.apple.com/documentation/localauthentication/accessing_keychain_items_with_face_id_or_touch_id>

Flutter secure storage package:
<https://pub.dev/packages/flutter_secure_storage>

flutter\_secure\_storage is simple package and I have not seen any option to add biometric prompt on storage access.

Is there any way to add biometrics prompt on access to secure storage in from Flutter program using existing packages?
