libraries - add an authentication provider library for Entra Id/Azure/etc...

[baywet]

Similar to other language implementations we need an implementation for access token and authentication providers for Azure Identity/Entra Id.
The challenge being, there's no azure identity/microsoft authentication library for dart, so we'll need to select an open source OAuth library like we did in PHP and other languages.

I used:

https://github.com/Earlybyte/aad_oauth.

I only need to provide a AccessTokenProvider callback function.

Notes from a couple of meetings:

• azure folks have no plans to ship a Dart Azure identity/msal today and for the foreseeable future.
• a generic OAuth authentication provider based on a well known and adopted Dart OAuth library would be beneficial
• we could then specialize further this library as an additional package with azure defaults (endpoints etc...)

@baywet now that the oauth library exists, can you query some colleagues whether they'd now be interested in developing an azure auth package?

I did have a conversation about that with my manager yesterday. Before we commit any resources to this, we'd like to see a strong demand. Anybody looking at this message and interested in an authentication provider for Azure Identity platform (entra, etc...), should upvote the issue. Also leave a comment about which credential flow is more interesting to you.

We also have an upcoming Fix Hack Learn week next week at Microsoft (internal hackathon), this could be a good project. Microsoft readers, please reach out if you want to take this on and have any questions.

A small, standard OAuth flow from Microsoft for Dart and especially for Flutter would be great.
I think people don’t use it at the moment because it’s too hard to implement without a good, simple standard from you guys.

Dart is a rising language, especially with Flutter and its use for mobile apps. It’s actually weird that you don’t support it yet, even now while creating Kiota.
