BETA Warning #
⚠️ Attention: This project is currently in BETA.
This means that while we've worked hard to ensure its functionality there may still be bugs,
performance issues, or unexpected behavior.
Installation #
flutter pub add dfns_sdk_flutter
Concepts #
PasskeysSigner #
All state-changing requests made to the Dfns API need to be cryptographically signed by credentials
registered with the User.

Note: To be more precise, it's not the request itself that needs to be signed, but rather a "
User Action Challenge" issued by Dfns. For simplicity, we refer to this process as "request
signing".

This request signature serves as cryptographic proof that only authorized entities are making the
request. Without it, the request would result in an Unauthorized error.
While implementing a Flutter application your backend server will have to communicate with the DFNS API
to retrieve this challenge and pass it to your application, PasskeysSigner will be used to
register and authenticate a user.

A demo application using the SDK can be
found here. This demo application is to be
used in conjunction with
the delegated registration and login tutorial.
It is a replacement for the Android and iOS sections, you should read and execute all instruction written
above this section to get this demo running.
