getRestoreCredential method
Signs the challenge in request with the restore credential (restore
key) on the device and returns the assertion that must be sent to the
relying party server, exactly like authenticate.
Restore credentials only exist on Android. The default implementation
throws a PlatformException with the code
restore-credential-unsupported.
Implementation
Future<AuthenticateResponseType> getRestoreCredential(
AuthenticateRequestType request,
) async {
throw _restoreCredentialUnsupported();
}
