Question

I have a project related to scanning codes. The issue is that when I scan Data-Matrix codes on a black background, the scanner cannot detect them, but everything works fine on iOS. not detecting these codes (android)

0-0-0-

0000000000000

detecting these codes 33333333

What I tried

const ScannerCamera = forwardRef<ScannerAnimationRefI, ScannerCameraProps>( (props, animationRef) => { const device = useCameraDevice('back', { physicalDevices: ['wide-angle-camera'], });

const {hasPermission, requestPermission} = useCameraPermission();

useEffect(() => {
  if (!hasPermission) {
    requestPermission();
  }
}, [hasPermission, requestPermission]);

const [torch, setTorch] = useState<'on' | 'off'>('off');

return (
  <View style={styles.scannerContainer}>
    <View style={styles.scanner}>
      {device && hasPermission ? (
        <Camera
          {...props}
          torch={torch}
          device={device}
          style={StyleSheet.absoluteFillObject}
        />
      ) : null}
      <ScanerAnimation ref={animationRef} />
    </View>
    {hasPermission ? null : <CText RED>Нет разрешения на камеру</CText>}
    <CButton
      onPress={() => setTorch(prev => (prev === 'on' ? 'off' : 'on'))}
      outline>
      {torch === 'on' ? 'Выключить фонарик' : 'Включить фонарик'}
    </CButton>

  </View>
);

}, ); export default ScannerCamera;

///////////// const codeScanner = useCodeScanner({ codeTypes: ['qr', 'ean-13', 'ean-8', 'data-matrix'], onCodeScanned, });
