I also had this error when I built for Android the readme instructions were just a little wrong. If you look at the error

D:\android projects\flutter project\doc_scanner - Copy\flutter-simple-edge-detection-master\ios\Classes/edge_detector.hpp:1:10: fatal error: 'opencv2/opencv.hpp' file not found

it is looking for the opencv.hpp file, that exists in the package you downloaded from the web site, you just need to put it in the place your build script is asking for.

Thank you @natebgurutech. So it seems to be related to putting the opencv related files in the correct directories. If problem perists, please open a new issue and I will investigate.
