+# 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';
+```
+
+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
+LocalAuthentication localAuth = new 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);
+
+```
+
+### Exceptions
+
+There are 4 types of exceptions: PasscodeNotSet, NotEnrolled, NotAvailable and
+OtherOperatingSystem. 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.
+  }
+}
+```
+
+## Android integration
+
+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>
+```
