I will have a look at this as soon as possible, unfortunately I am really busy at the moment...

@Darkmagister sorry it took me so long to respond!

I was able to start your project without any issues, the only thing that prevented the scanner from being visible is the --ion-background-color css variable which need to be set to transparent. Otherwise I had no issues with your project on my Huawei test device.

Feel free to reopen this issue if the problem still exists!
