You need to invert the colors and have a white border around the image, like this:
The border around the image should have at least the width of the QRCode's pixel, so if the smallest square inside the image has 8×8px, then the border should have at least 8px.
The color outside the border can be white too.

I want to scan the qr code using this package react-native-qrcode-scanner, I am following this tutorial https://enappd.com/blog/react-native-qr-code-scanning-using-react-native-camera/117/ In the tutorial, the camera permission is given through manifest file, however I don't have this file in my expo project. I tried to add "permissions": ["CAMERA"] to app.json file but it didn't work so How can I add camera permission?...

Is there a specific reason you want to use that particular library, or are you using it simply because it is what is covered in the tutorial?
Expo has a barcode scanner library that will perform QR code scanning, here is the documentation: https://docs.expo.dev/versions/latest/sdk/bar-code-scanner/. This library can be used in the managed workflow (which you are using by the sounds of things) and the documentation is pretty straight forward.
Having looked at the library that you want to use, it will require linking which means you will have to eject your project to access the necessary files required for that - if there isn't any particularly requirement for you to use this library specifically, I would suggest steering clear of ejecting if it can be avoided.

Based on your package.json dependencies you dont have the
@react-native-async-storage dependency, you have
@react-native-community/async-storage, which is the old organisation namespace.
I am now using react-native-qrcode-scanner to read the QRcode but now have trouble when trying to add the text inside of the camera view. (Not top or bottom of the camera view but inside of it - more exactly under the marker position with align center)
The text is not displayed even though I add Text field with position: 'absolute'

I want to scan GS1 Databar Barcode which is also known as RSS Expanded barcode in IOS with react-native, I am using react-native-qrcode-scanner https://github.com/moaazsidat/react-native-qrcode-scanner to scan barcodes....
ANSWERAnswered 2021-Apr-05 at 14:57
No efficient open source solutions found for scanning GS1 Databar Expanded barcodes on iOS using React-Native.
Tried Zxingify-ObjC as a native module but the scanning is poor on newer iPhones (11 Pro, 12).
Tried react-native-barcode plugin. Doesn't support GS1 Databar plugin using the camera scanner, but does support scanning GS1 Databar from static images.
Finally went for a paid SDK: Cognex.
Hope this helps someone who runs into the same problem.
