clientCredentials not working on Google Pixel 7 with Android 13

[cc13com]

Hello,

I used your package together with the oauth2 package in my flutter app on my old mobile with Android 10 (armeebi-v7a apk) for a long time. Since I use a new Pixel 7 with Android 13 I installed the application (arm64-v8a apk) but the http request to my rest api via oauth2 clientCredentials is not longer working.

For testing I created a new virtual device with Android 13 and started the app in VSC with the virtual device and it works fine without code changes. But not on my device. The CircularProgressIndicator is showing the whole time but no error message e.g.

In the same app there is a http request to a rest api without login needed and that works. Therefore the network connection on the smartphone is ok.

Any idea to solve this?
