Wow, that looks nice!

Not sure about the quality of the flutter package though, that has to be evaluated.

The flutter package mentioned above (or rather, some of the more recent forks) generally work. The caveat is that they still return a single image file for each scanned page. It should be possible to merge those into one pdf using native code, since there is also something called PdfKit.

The alternative would be to merge the images into a pdf in flutter. I will continue looking into this.

Thanks @CTimmermann - I saw your commit related to PDFs as well which I really appreciate. Together, these two features would make the app really useful
