Getting Platform Exception on Android

[ewm003]

Hoping to get some help. This is my first time using OAUTH2. I am currently just using a test app for my education to test the flow before I integrate it into my production app. I am authenticating with Teamsnap API, using the token flow. It is working great on iOS but on Android I have been running into issues. I think I got the call back issue fixed but now it looks like it authenticates but I get a null result from the authentication. Looks like the platform exception may be causing the issue.

I am not canceling the login, just putting in my information and then clicking login, then it goes back to my app and I get the error above.

Here is what my code looks like,

And my android manifest in case you need it.

Thanks in advance for your help!

Getting the same issue with android. Any help would be much appreciated 🙏

Hey I found the issue, it's because the callbackUrlScheme provided in the authenticate function is incorrect.

@ewm003 try replacing your callbackUrlScheme from hcassistant://ejappdev.com to hcassistant and the redirect should be caught by the FlutterWebAuth properly.

Thanks for looking at this!! I will give that a go and let you know how it turns out.

That worked, it now gets the token from the server!! Thanks guys, it's amazing what another set of eyes will do, I had been staring at that code for a long time and hadn't even thought that would be the problem since it was working on the iOS version.
