How to scan QR codes with dark background

[aelaboussi]

I can't scan qrcodes / datamatrix with dark background, is there a way to achieve that ?

used deps:

  "dependencies": {
    "@mgcrea/vision-camera-barcode-scanner": "^0.12.3",
    "@react-native/new-app-screen": "0.81.1",
    "react": "^19.1.0",
    "react-native": "0.81.1",
    "react-native-safe-area-context": "^5.5.2",
    "react-native-vision-camera": "^4.7.2",
    "react-native-worklets-core": "^1.6.2"
  },

Code snippet:

<Camera
    style={StyleSheet.absoluteFill}
    device={device}
    isActive
    {...cameraProps}
/>

Tried to play with Camera's props but couldn't fix it.

edit: i have switched to react-native-camera-kit and it works well.

Hi @aelaboussi, does react-native-camera-kit correctly scan all barcode & qrcode. I use expo-camera and sometimes it give wrong output, takes time to scan
