Well, I do not know... but I would take a look at the App Inventor sources to find it out...
here they are appinventor-sources/appinventor/components/src/com/google/appinventor/components/runtime at master · mit-cml/appinventor-sources · GitHub

You can use the YailDictionary class (in App Inventor sources) to get and return AI2 dictionary values in your extension.
