'What is the proper usage of NSColorPanel's colorDidChangeNotification?
I am writing a Flutter macOS plugin that allows the user to launch the native macOS color picker and stream back their color selections via EventChannel.
I am able to launch the picker, but the color selection does not get streamed back. I believe this is because I am not making use of colorDidChangeNotification, which appears to be a handler for color selection changes for the current NSColorPanel. I have not been able to find an example for this function. What is the proper way to use it?
