Today 4 January, is no more possibile to compile/publish the app with the qr code feature. It fails with the following error:
Error: Unable to resolve module react-native-camera from /home/gradle/builds/AdaloApp/node_modules/qr-code-scanner/src/components/QrCodeScanner/index.js: react-native-camera could not be found within the project or in these directories:
node_modules
The problem appears also with a new app.
Yesterday worked fine without problem. The problems appear today.
The very last item is QR Scanner, install that. It will show up in your Private section of your components. Replace the QR scanner that you currently have, and uninstall if from the Adalo Marketplace, and use the one from PF.
If you do not know how use the PF marketplace, see this
