            QR code generated but it is not scannable - React Native
            Asked 2022-Mar-03 at 15:41

            I have generated QR code using

            "react-native-qrcode-svg": "^6.1.2", "react-native-svg": "^12.1.1",

            Generated QR Code is like this, qr code

            Not getting any result after scanning this.

            This is the code,



            Answered 2022-Mar-03 at 15:41

            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.

            The below code is a simple app which contain two screens Home and Settings. For Navigation, I am using React Navigation library.

            You can use Tab navigation, you need just to change your Stack.Navigation for Tab.navigation



            Invariant Violation: Native module cannot be null.only IOS not android
            Asked 2022-Jan-20 at 05:12

            i have the Invariant Violation: Native module cannot be null error and the 2nd error down below. I found online the issue might have to do with not having an ios folder in a module directory, i looked in each of the folders in the local system and on github with them all containing the ios folder



            Answered 2022-Jan-20 at 05:12

            Check the library @react-navigation/drawer compatibility with IOS and Android respectively , link it manually sometimes autolinking doesn't work. Ensure you are running correct project , clean build and install pod and check it out.



            How to add camera permission in react native
            Asked 2021-Dec-31 at 11:34

            I want to scan the qr code using this package react-native-qrcode-scanner, I am following this tutorial 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?



            Answered 2021-Dec-31 at 11:34

            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: 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.

            How to add text inside of the Camera View when using react-native-qrcode-scanner in react native
            Asked 2021-Nov-15 at 16:41

            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'

            You can simply add quietZone props to QRCode component. This props is the margin around the QR-code and when yo save the QR it is shown!!

            Scanning GS1 Databar Barcode in IOS with react-native
            Asked 2021-Apr-05 at 14:57

            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 to scan barcodes.



            Answered 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.
