In order to solve the swipe-out action on ios 13, I thought it was a good idea to trigger a closing of the scanning session whe user swipe the dialog out.
I have added two properties in class CDVbcsProcessor
In the CDVbcsViewController class there is now a method viewWillDisappear that is triggered when the scanning dialog is about to close. When the dialog is about close and it doesn't happen due to a successful scan or a cancel of the dialog, then
the barcodeScanCancelled is invoked.
