Why not have a state variable for the torch?

[zoobibackups]

const [torch,setTorch] = useState(false);
const toggleFlash =() => {
cameraRef.current?.CameraDevice({
hasTorch: 'on',
})
setTorch(!torch)
}

but error is that cameraRef.current.CameraDevice is not a function it is undefined

[bruno-centanaro]

but why is it not a prop of the camera component? With this
So it should be something like torch={torch ? 'on' : 'off'}
