Unity-Flutter-AR-Foundation-example

This project aims to enable users to have AR experiences for iOS and for Android. This is made possible by the game engine Unity and its package: AR Foundation. To bring the AR experience from Unity to Flutter, the plugin "flutter_unity" from Glartek is used. In the example scene, the user can test an AR scene with an printed reference image which is an example of image tracking. Have fun
