I have a case of making AR for Android, but the problem is without using ARCore from Google and in the application not only AR there are several features with a fairly complex GUI. The main problem is that the cellphones of my customers do not necessarily support ARCore.

I tried to search for AR in the playstore to try whether AR applications should require ARCore, I tried 1 application and found that it could run well and only required camera and video permissions, and the application in it had an attractive GUI.

I wondered how they made it?

Yesterday I tried to make AR in Flutter with the help of the arcore_flutter_plugin library, but the kotlin version was outdated, I tried ar_flutter_plugin but the same kotlin version was also outdated, and I finally tried ar_flutter_plugin_flutterflow, this is the latest version of ar_flutter_plugin but this requires ARCore too.

Today I tried React Native with the viro library, I used the sample repository from https://github.com/ReactVision/starter-kit.git but when I run it still requires ARCore.

I don’t know if it really requires ARCore but when I have given the camera permission the program immediately checks whether ARCore is present on my device or not.

Please help.

Recommend me a free platform / framework for AR development that can run on Android without ARCore aka capitalizing on the camera alone.
