biometric_auth

Description:

biometric auth

biometric_auth #
This package provides a stateful widget to perform local, on-device authentication of the user referring to biometric authentication on iOS (Touch ID or lock code) and the fingerprint APIs on Android (introduced in Android 6.0).
Getting Started #
To use this widget, add biometric_auth as a dependency in your pubspec.yaml file.
The widget implementation uses the StatefulWidget named BiometricWidget which receives a title which gets displayed on the dialog of
the native biometric interface when popped up.
Checkout the sample below for usage of the widget.
Example #
import 'package:flutter/material.dart';
import 'package:biometric_auth/biometric_auth.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return BiometricWidget(
title: "Confirm your Fingerprint now",
child: MaterialApp(
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Fingerprint Authentication'),
)
);
}
}

class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;

@override
_MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

@override
Widget build(BuildContext context) {
var biometric = BiometricWidget.of(context);
bool hasFingerPrintSupport = biometric.hasFingerPrintSupport;
String authorizedOrNot = biometric.authorizedOrNot;
var availableBiometricType = biometric.availableBiometricType;
var authenticateMe = biometric.authenticateMe;

return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text("Has FingerPrint Support : $hasFingerPrintSupport"),
Text(
"List of Biometrics Support: ${availableBiometricType.toString()}"),
Text("Authorized : $authorizedOrNot"),
RaisedButton(
child: Text("Authorize Now"),
color: Colors.green,
onPressed: authenticateMe,
),
],
),
),
);
}
