Error 'opencv2/core/core.hpp' file not found in ios

[ldthinh]

Hi author and community,

First of all, thanks for open-source being very useful for developers.
I am developing a plugin/library for Flutter, and everything is fine for Android but when using opencv.framework (v4.8.0, release v19)for ios I encountered the issue " 'opencv2/ core/core.hpp' file not found" , because I didn't find any demos or examples of using this library for iOS, I don't know whether this is an error due to this library or because I am lacking in its configuration, I have attached the source code here for convenience in reproducing for iOS. I greatly appreciate it when someone has found a solution to this problem.

Thanks

sorry, I have no idea, but we may learn header_dir from

https://github.com/CocoaPods/Specs/blob/master/Specs/e/a/f/OpenCV2/4.3.0/OpenCV2.podspec.json

  "preserve_paths": "opencv2.framework",
  "source_files": "opencv2.framework/Versions/A/Headers/**/*{.h,.hpp}",
  "public_header_files": "opencv2.framework/Versions/A/Headers/**/*{.h,.hpp}",
  "vendored_frameworks": "opencv2.framework",
  "header_dir": "opencv2",

@ldthinh Out of curiosity, have you made any progress with the Flutter plugin?
