The mobile_scanner plugin for web doesn't implement the method 'updateScanWindow'

[thomtomdup]

Hello.

When i changed the permission of camera denied to autorised i have this error in console :

Error: PlatformException(Unimplemented, null, The mobile_scanner plugin for web doesn't implement the method 'updateScanWindow', null)

Can you tell me if it's normal ?

Thank you.

Same error message here. Error also seems to occur when disposing a page with MobileScanner widget in it.

(only in web of course :-))

Is there any solution for this? (seeing this error in web)

_methodChannel.invokeMethod('updateScanWindow', {'rect': data});

This invokes native methods inside kotlin and switf where we have updateScanWindow methods but web doesn't.

@juliansteenbakker would @ribeiro-gabriel proposition to opt-out conditionally of this callback on web platform be enough ? Is the underlying JS library supposed to acknowledge this method call ? 🙏

I am also getting the same error when click on the back arrow in the app bar.

This was implemented to ignore the scan window on the web, since ZXing does not provide the size of the barcode. So the crash should no longer occur.

We could however, decide to make a rectangle with the points of the barcode and do an intersection.
