Why not have a state variable for the torch?

[zoobibackups]

const [torch,setTorch] = useState(false); const toggleFlash =() => { cameraRef.current?.CameraDevice({ hasTorch: 'on', }) setTorch(!torch) } <Camera hasTorch={torch} ref={cameraRef} style={StyleSheet.absoluteFill} device={device} isActive={isActive} />

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'}
