Scan images from device

[modulovalue]

I think it is an important feature to be able to scan QR codes not only from the camera but also from an image that was previously taken or downloaded from the web.

Use case:

• Cryptocurrency addresses are often presented in the form of QR codes. Addresses are cryptic and not user-friendly therefore it is much more practical to share QR codes than the addresses themselves.

Two features would be needed:

1. an image picker like this library
2. Libraries to scan the images

Solution

One approach is to additionally use other libraries for iOS/Android that support this feature. e.g. iOS and Android

The other way would be to kindly ask here and here if they could implement this feature. It doesn't seem to be a big deal but I might be overlooking something.

What do the maintainers of this library think of that?

I think this falls outside the scope of this library. I would recommend making a separate plugin that uses the build in libraries in iOS and Android instead.
