@tdhman
It's pretty gross and I am not proud of it, but you need to configure beepOnScan = false. Then create an instance of the barcode scanner class. Apply the properties to the class. I am using an angular service which wraps the scanner, but you don't have to do that. The reason it works is because there is an _addVolumeObserver method which will return if there is no _observer. This is intended to be a temporary hack. Hopefully, @EddyVerbruggen can possibly take a look.
config.beepOnScan = false;
const scanner = new BarcodeScanner();
if (scanner['_observer']) {
scanner['_observer']['_owner'] = undefined;
scanner['_observer'] = undefined;
}
return scanner.scan(config);

This will fix it #278 - the actual instance was undefined and was still getting passed the (!this._observer) check so it would crash when adding it. Fix tested and works on iOS 15 and NS 8.1. Demo app functioning in that PR confirmed.

Yeah this is a known problem with NS v8.1. You can try the temporary hack:
const scanner = new BarcodeScanner();
if (scanner['_observer']) {
scanner['_observer']['_owner'] = undefined;
scanner['_observer'] = undefined;
}
return scanner.scan(config);from nativescript-barcodescanner.

@bmacdonald Hello, I got the same issue on NS 8.1.0. How do you apply temporary fix for this issue ?

One more tidbit of information about the crash, it looks like it is only occurring on the phones and ipad pro. It does not seem to crash on regular ipads.

I'm also getting the same crash with NativeScript 8.1 on iPhone X iOS 14.

@eikaramba given the activity record of Eddy lately, I doubt anything would change in this repo anytime soon.
You need to pull the same plugin from @nstudio namespace - @nstudio/nativescript-barcodescanner which is up-to date and includes the solution of this problem.
