As mentioned in #4, please add the full path of dist to your computer's LD_LIBRARY_PATH for Dart to find it.

It should be part of the readme.

Thanks it worked

It is:

Add the dist folder to your PATH. Restart your terminal/IDE and run your project as normal.

The script will output a command to add the dist folder to your LD_LIBRARY_PATH. You only need to run this command once, even if you modify and rebuild OpenCV, but you must run it again if you move the dist folder.
