Question 1

Is react-native-barcodescanner still supported or should I use something else?

Accepted Answer

No, it's deprecated and unmaintained. The author recommends using react-native-camera instead, which offers cross-platform support and more robust features. For new projects, avoid this library to ensure long-term compatibility.

Question 2

How to scan QR codes in a React Native Android app?

Accepted Answer

If using react-native-barcodescanner, integrate it via manual linking as per the README, but it's better to use react-native-camera with its barcode scanning module. Set up the camera component and handle the onBarCodeRead event for data capture.

Question 3

What barcode formats does react-native-barcodescanner support?

Accepted Answer

It supports common formats like UPC, EAN, Code 128, QR Code, and Data Matrix, as listed in the properties section. This is based on the ZXing library, but for wider format support, consider alternatives like react-native-camera.

Question 4

react-native-barcodescanner vs react-native-camera: which is better?

Accepted Answer

react-native-camera is better for most use cases because it's actively maintained, cross-platform, and includes barcode scanning along with other camera features. react-native-barcodescanner is deprecated and Android-only, so it's only suitable for legacy Android apps.

Question 5

Can I use react-native-barcodescanner with React Native 0.60 or higher?

Accepted Answer

Probably not, as its dependencies are tied to older React Native versions (e.g., 3.x.x for RN >=0.25). You might encounter linking issues or crashes, so migrating to react-native-camera is advised for compatibility.

Question 6

How to customize the viewfinder in react-native-barcodescanner?

Accepted Answer

Use properties like viewFinderBorderColor, viewFinderWidth, and viewFinderShowLoadingIndicator from the README to style the viewfinder. However, since the library is deprecated, consider implementing custom UI in react-native-camera for future-proofing.

Question 7

Why did react-native-barcodescanner get deprecated?

Accepted Answer

The author deprecated it because react-native-camera added barcode scanning for both iOS and Android, offering a more robust and unified solution. Maintaining a separate Android-only library became redundant and less efficient.
