implementation "org.mozilla.components:feature-qr:{latest-version}"
```

### Integration

Initializing the feature:

```kotlin
qrFeature = QrFeature(
    context,
    fragmentManager = supportFragmentManager,
    onNeedToRequestPermissions = { permissions ->
        requestPermissions(this, permissions, REQUEST_CODE_CAMERA_PERMISSIONS)
    },
    onScanResult = { result ->
        // result is a String (e.g. a URL) returned by the QR scanner.
