const handleDevices = React.useCallback(
mediaDevices =>
 setDevices(mediaDevices),[setDevices]
);

React.useEffect(
 () => {
  navigator.mediaDevices.enumerateDevices().then(handleDevices);
 },
 [handleDevices]
);

 return (
  <Picker>
     {
        devices.map((device, key) => device.kind ==="videoinput" 
        ? <Picker.Item value={device.deviceId } >{device.label || `Device ${key + 1}`}</Picker.Item>
        : null
     )}
  </Picker>
 }
export default Customer;
