const FunctionalComponentExample = ({ initialProps }) => {
  const [ 
    { cameraRef, type, ratio, autoFocus, autoFocusPoint, isRecording },
  ] = useCamera(initialProps);
  return (
    <View style={{ flex: 1 }}>
        style={{ flex: 1 }}
          flex: 1,
        style={{ width: '100%', height: 45 }}>
      {!isRecording && (
          onPress={async () => {
            try {
              const data = await recordVideo();
            } catch (error) {
            } finally {
          style={{ width: '100%', height: 45 }}
