I'm trying to get dart bindings for a static library to work on iOS.
So far, I've gotten the plugin's example project to compile, but I get the following error when I try to use the native functions at runtime:

Invalid argument(s):
Failed to lookup symbol 'NDIlib_version': dlsym(RTLD_DEFAULT, NDIlib_version):
symbol not found

From what I've read, it may be caused by XCode excluding the library while optimizing the app because it doesn't detect that the library is being used.

So far, I've tried turning off dead code stripping in XCode, but it didn't make a difference:

Here's a minimal project that can be used to reproduce the error:

Any help would be appreciated.
