Auth3 Flutter Login
The official Auth3 Flutter Login library.
Introduction
This library provides a quick and secure way to integrate with the Auth3 Identity Platform to protect your mobile Flutter application running across different devices.
For additional help and a guided walkthrough, with an example reference application and further reasoning, check out our article here.
Platform support
Our libraries can be run on the following environments:
- iOS
- Android
- Mac OS
- Web (flutter web)
Installation
To depend on this library run:
flutter pub add auth3_login
Alternatively, add to your pubspec.yaml
:
auth3_login: <version> # find the latest version on https://pub.dev/packages/auth3_login
Then run:
pub get
Setup
Android
In order to capture the callback url, the following activity needs to be added to your AndroidManifest.xml
. Be sure to relpace YOUR_CALLBACK_URL_SCHEME_HERE
with your actual callback url scheme (auth3
by default on mobile platforms, https
on the web).
<manifest>
<application>
<activity android:name="com.linusu.flutter_web_auth.CallbackActivity" android:exported="true">
<intent-filter android:label="flutter_web_auth">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="YOUR_CALLBACK_URL_SCHEME_HERE" />
</intent-filter>
</activity>
</application>
</manifest>
Web
On the Web platform an endpoint must to be created that captures the callback URL and sends it to the application using the JavaScript postMessage()
method. In the ./web
folder of the project, create an HTML file with the name e.g. auth.html
with content:
<!DOCTYPE html>
<html>
<title>Authentication completed</title>
<p>If this does not happen automatically, please close the window.</p>
<script>
window.opener.postMessage({
'flutter-web-auth': window.location.href
}, window.location.origin);
window.close();
</script>
</html>
