Describe your issue here:
Many times it happens that i have the qr code that i wanna scan saved in my phone on a screenshot or something. I like it when there is the option to scan a qr code selecting that picture from the gallery.

Expected behaviour

Tap the button to scan qr code, the user should expect an option on the screen to select image from gallery if he wants to.

Actual behaviour

When tapping the scan qr code button there is no "select image" option, nothing but only the camera waiting to see a qr code.

Would you like to work on the issue?

Yes i'd like to contribute and fix this issue. Perhaps add a little "select image" option that opens up the user's gallery and he can select a picture.
