This package gives you beautiful pass code page for using both android and ios.
iOS Integration Note that this plugin works with both TouchID and FaceID. However, to use the latter, you need to also add:
<key>NSFaceIDUsageDescription</key>
<string>Why is my app authenticating using face id?</string>
to your Info.plist file. Failure to do so results in a dialog that tells the user your app has not been updated to use TouchID.
Android Integration Update your project's AndroidManifest.xml file to include the USE_FINGERPRINT permissions:
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
package="com.example.app">
<uses-permission android:name="android.permission.USE_FINGERPRINT"/>
<manifest>
It is really easy to use!
You should ensure that you add the flutter_lock_screen as a dependency in your flutter project.
dependencies:
flutter_lock_screen: '^1.0.4'Than you can use it with below example.
import 'package:flutter/material.dart';
import 'package:local_auth/local_auth.dart';
import 'package:testapp/empty_page.dart';
import 'package:flutter/services.dart';
class PassCodeScreen extends StatefulWidget {
PassCodeScreen({Key key, this.title}) : super(key: key);
final String title;
@override
_PassCodeScreenState createState() => new _PassCodeScreenState();
}
class _PassCodeScreenState extends State<PassCodeScreen> {
bool isFingerprint;
Future<Null> biometrics() async {
final LocalAuthentication auth = new LocalAuthentication();
bool authenticated = false;
try {
authenticated = await auth.authenticateWithBiometrics(
localizedReason: 'Scan your fingerprint to authenticate',
useErrorDialogs: true,
stickyAuth: false);
} on PlatformException catch (e) {
print(e);
}
if (!mounted) return;
if (authenticated) {
setState(() {
isFingerprint = true;
});
}
}
@override
Widget build(BuildContext context) {
var myPass = [1, 2, 3, 4];
return LockScreen(
title: "This is Screet ",
passLength: myPass.length,

fingerPrintImage: "images/fingerprint.png",
showFingerPass: true,

fingerVerify: isFingerprint,
borderColor: Colors.white,
showWrongPassDialog: true,
wrongPassContent: "Wrong pass please try again.",
wrongPassTitle: "Opps!",
wrongPassCancelButtonText: "Cancel",
passCodeVerify: (passcode) async {
for (int i = 0; i < myPass.length; i++) {
if (passcode[i] != myPass[i]) {
return false;
}
}
return true;
},
onSuccess: () {
Navigator.of(context).pushReplacement(
new MaterialPageRoute(builder: (BuildContext context) {
