GoogleARCore.Trackable

Caution: The ARCore SDK for Unity is deprecated, and no longer supported in Unity 2020 and later. This SDK should only be used by developers working on existing projects which are unable to migrate to Unitys AR Foundation.

Key Point: Developers starting new projects should instead use the ARCore Extensions for AR Foundation with Unity.

An object ARCore is tracking in the real world.
