fun onSurfaceSession(block: suspend ViewfinderSurfaceSessionScope.() -> Unit): Unit
Registers a callback to be invoked when a new ViewfinderSurfaceSessionScope is created.
The provided callback will be invoked each time a new ViewfinderSurfaceSessionScope is available. If a new ViewfinderSurfaceSessionScope is available, the previous one will be cancelled before block is invoked with the new one.
The provided callback will always be invoked from the main thread.
