I just tested it on simulator and it worked fine.

And I checked the symbols of opecv_dart.framework with

symbols opencv_dart | grep IMRead

and it shows the symbol exists

So, please check your opencv_dart version and whether you have run dart run opencv_dart:setup after added.

I have updated my test code in https://github.com/rainyl/opencv_dart/tree/main/example , (remember change opencv_dart to v1.0.0+1 in pubsepc.yaml, 1.0.0+2 not published yet), then run setup and example

BTW, also note that every time you want to switch between different arch, you need to run setup again, for example, if you develop and test on a simulator, you need to run dart run opencv_dart:setup ios -a x64, now you want to switch to a real device, you need to run dart run opencv_dart:setup ios -a arm64, this is because the opencv_dart.framework will be placed in opencv_dart/ios, for both arch.
