class UARDependencyHandler :

public IModularFeature

Remarks

Helper class that allows the user to explicitly request AR service installation and permission granting. Recommended flow for explicit management:

Call "GetARDependencyHandler" to get a handler, if valid:

Call "CheckARServiceAvailability" to check availability, if the device is supported:

Call "InstallARService" to install AR service dependency, if installed:

Call "RequestARSessionPermission" to request permission, if granted:

Call "UARBlueprintLibrary::StartARSession" to start the session. Alternatively, you can also call "StartARSessionLatent" which handles dependency and permission internally.
