native_auth

With this pack you can use the biometrics systems of Android and IOS devices.

It will ask for the user which the biometric authentication method of his device, this can be FaceID or TouchID on IPhone or FingerPrint on Android phone

How to use

import 'package:native_auth/native_auth.dart';
final response = await Auth.isAuthenticate();
print(response.isAuthenticated); // true or false

response is an enum AuthResult containing the statuses:

error, auth and noAuth

auth means the user is authenticated.
noAuth means the user is no authenticated.
error means that it was not possible to request any biometrics.
