kashi_auth

Flutter half of @softwareseva/auth. Depends only on kashi_core and kashi_ui; native plugins (Google, Apple, passkeys, biometrics) plug in through small adapters the app owns, so apps that use only one-time codes do not inherit other plugins' platform requirements.

KSignIn(
  google: googleIdToken,        // IdTokenSignIn, see the flutter-auth skill templates
  apple: appleIdToken,
  passkeys: PluginPasskeyBridge(),
)

• KashiAuthApi: config, OTP request/verify, password, Google/Apple ID tokens, passkey sign-in and registration, passkey list/rename/remove.
• KSignIn: Cupertino sign-in body that shows every provider the server enables and the app supplies an adapter for.
• KPasskeySettings: add, list and remove passkeys.
• KBiometricGate: locks the app after it has been in the background.
