Crash when user decline camera permission on Android

[Nielsticot]

Hello,

I'm testing with a Google Pixel 2 on android 9,

Each time I decline the camera permission, the onError parameter of QrCamera is not called, instead, it throws an exception.

I tested it on your provided example and it reacted exactly the same way.

Here is the console log :
