+
+## Finger Print Usage
+First, be sure you should ensure that you add the `local_auth` package as a dependency. And Please read local_auth all integration details.
+https://pub.dartlang.org/packages/local_auth
+
+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
+Note that local_auth plugin requires the use of a FragmentActivity as opposed to Activity. This can be easily done by switching to use FlutterFragmentActivity as opposed to FlutterActivity in your manifest (or your own Activity class if you are extending the base class).
+
+Update your project's AndroidManifest.xml file to include the USE_FINGERPRINT permissions:
+```
+<manifest xmlns:android="http://schemas.android.com/apk/res/android"
+          package="com.example.app">
+  <uses-permission android:name="android.permission.USE_FINGERPRINT"/>
+<manifest>
+```
+
+## Usage
+It is really easy to use!
+You should ensure that you add the `flutter_lock_screen` as a dependency in your flutter project.
+
+```yaml
+dependencies:
+  flutter_lock_screen: '^2.0.1'
+```
+Than you can use it with below example.
+
+```dart
+import 'package:flutter/material.dart';
+import 'package:local_auth/local_auth.dart';
+import 'package:testapp/empty_page.dart';
+import 'package:flutter/services.dart';

+        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) {
+            return EmptyPage();
+          }));

+# local_auth
+
+This Flutter plugin provides means to perform local, on-device authentication of
+the user.
+
+This means referring to biometric authentication on iOS (Touch ID or lock code)
+and the fingerprint APIs on Android (introduced in Android 6.0).
+
+## Usage in Dart
+
+Import the relevant file:
+
+```dart
+import 'package:local_auth/local_auth.dart';
+```
+
+To check whether there is local authentication available on this device or not, call canCheckBiometrics:
+
+```dart
+bool canCheckBiometrics =
+    await localAuth.canCheckBiometrics;
+```
+
+Currently the following biometric types are implemented:
+
+* BiometricType.face
+* BiometricType.fingerprint
+
+To get a list of enrolled biometrics, call getAvailableBiometrics:
+
+```dart
+List<BiometricType> availableBiometrics =
+    await auth.getAvailableBiometrics();
+
+if (Platform.isIOS) {
+    if (availableBiometrics.contains(BiometricType.face)) {
+        // Face ID.
+    } else if (availableBiometrics.contains(BiometricType.fingerprint)) {
+        // Touch ID.
+    }
+}
+```
+
+We have default dialogs with an 'OK' button to show authentication error
+messages for the following 2 cases:
+
+1.  Passcode/PIN/Pattern Not Set. The user has not yet configured a passcode on
+    iOS or PIN/pattern on Android.
+2.  Touch ID/Fingerprint Not Enrolled. The user has not enrolled any
+    fingerprints on the device.
+
+Which means, if there's no fingerprint on the user's device, a dialog with
+instructions will pop up to let the user set up fingerprint. If the user clicks
+'OK' button, it will return 'false'.
+
+Use the exported APIs to trigger local authentication with default dialogs:
+
+```dart
+var localAuth = LocalAuthentication();
+bool didAuthenticate =
+    await localAuth.authenticateWithBiometrics(
+        localizedReason: 'Please authenticate to show account balance');
+```
+
+If you don't want to use the default dialogs, call this API with
+'useErrorDialogs = false'. In this case, it will throw the error message back
+and you need to handle them in your dart code:
+
+```dart
+bool didAuthenticate =
+    await localAuth.authenticateWithBiometrics(
+        localizedReason: 'Please authenticate to show account balance',
+        useErrorDialogs: false);
+```
+
+You can use our default dialog messages, or you can use your own messages by
+passing in IOSAuthMessages and AndroidAuthMessages:
+
+```dart
+import 'package:local_auth/auth_strings.dart';
+
+const iosStrings = const IOSAuthMessages(
+    cancelButton: 'cancel',
+    goToSettingsButton: 'settings',
+    goToSettingsDescription: 'Please set up your Touch ID.',
+    lockOut: 'Please reenable your Touch ID');
+await localAuth.authenticateWithBiometrics(
+    localizedReason: 'Please authenticate to show account balance',
+    useErrorDialogs: false,
+    iOSAuthStrings: iosStrings);
+
+```
+
+If needed, you can manually stop authentication for android:
+
+```dart
+
+void _cancelAuthentication() {
+    localAuth.stopAuthentication();
+}
+
+```
+
+### Exceptions
+
+There are 6 types of exceptions: PasscodeNotSet, NotEnrolled, NotAvailable, OtherOperatingSystem, LockedOut and PermanentlyLockedOut.
+They are wrapped in LocalAuthenticationError class. You can
+catch the exception and handle them by different types. For example:
+
+```dart
+import 'package:flutter/services.dart';
+import 'package:local_auth/error_codes.dart' as auth_error;
+
+try {
+  bool didAuthenticate = await local_auth.authenticateWithBiometrics(
+      localizedReason: 'Please authenticate to show account balance');
+} on PlatformException catch (e) {
+  if (e.code == auth_error.notAvailable) {
+    // Handle this exception here.
+  }
+}
+```
+
+## iOS Integration
+
+Note that this plugin works with both TouchID and FaceID. However, to use the latter,
+you need to also add:
+
+```xml
+<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
+
+Note that local_auth plugin requires the use of a FragmentActivity as
+opposed to Activity. This can be easily done by switching to use
+`FlutterFragmentActivity` as opposed to `FlutterActivity` in your
+manifest (or your own Activity class if you are extending the base class).
+
+Update your project's `AndroidManifest.xml` file to include the
+`USE_FINGERPRINT` permissions:
+
+```xml
+<manifest xmlns:android="http://schemas.android.com/apk/res/android"
+          package="com.example.app">
+  <uses-permission android:name="android.permission.USE_FINGERPRINT"/>
+<manifest>
+```
+
+On Android, you can check only for existence of fingerprint hardware prior
+to API 29 (Android Q). Therefore, if you would like to support other biometrics
+types (such as face scanning) and you want to support SDKs lower than Q,
+*do not* call `getAvailableBiometrics`. Simply call `authenticateWithBiometrics`.
+This will return an error if there was no hardware available.
+
+## Sticky Auth
+
+You can set the `stickyAuth` option on the plugin to true so that plugin does not
+return failure if the app is put to background by the system. This might happen
+if the user receives a phone call before they get a chance to authenticate. With
+`stickyAuth` set to false, this would result in plugin returning failure result
+to the Dart app. If set to true, the plugin will retry authenticating when the
+app resumes.
