Flutter SSO (Single Sign On) through SAML

Question

I want to add authentication through SAML in flutter app.But I didn't find any helpful doc or package for integration with flutter.

So any suggestion will be of great help.

Answer 1

At the moment, there is no official package or documentation available for integrating SAML with Flutter.

However, I can give you an idea of what the process might look like, and the steps you will need to take in order to implement SAML authentication in your app.

1. Create a backend service that handles the SAML authentication process. This service should be able to receive a request from the app, redirect the user to the SAML identity provider, handle the authentication process, and return the authentication response to the app.

2. In your Flutter app, use the http package to make a request to the backend service and initiate the SAML authentication process.

3. Once the user is authenticated, the backend service will return an authentication token to the app. You can then use this token to make authorized requests to other backend services or APIs.

4. To handle the SAML logout process, you can use the Single Logout (SLO) profile of SAML. This will allow you to end the session on all the service providers on which the user is logged in, by sending a logout request to the identity provider.

5. To implement SAML authentication using webview, you can use the webview_flutter package, and configure it to redirect to the SAML identity provider when the user attempts to log in. You can also use the JavaScriptChannel of webview_flutter package to communicate with the webview and handle the authentication process.
