How to detect Radaee PDF close event

I am trying to detect when the user closes the PDF reader so that I can store the page he is on when he closes it.

I do not see any methods for this event in the plugins js file. I know we have the RadaeePDFPlugin.getPageNumber function, but I still need to be able to bind it to the closing of the PDF reader to get the last page the user reads.

Does this plugin have a method that I missed, or is there a way to manipulate the getPageNumber function so that I can get the page the user is on when he closes the PDF reader.

Thanks in advance,
-Stacy.

You can use the following callbacks:
Android (com.radaee.cordova.RadaeePDFPlugin.java):
RadaeePDFPlugin.willCloseReader
iOS:
WillCloseReader in RadaeePDFPluginDelegate

Can you provide a working example of how to use the functions as callbacks?
I'm struggling with how to correctly call the RadaeePDFPlugin.willCloseReader() to be able to detect when the user closes the reader.

It's a callback (listener) that will be fired immediately before the closure of the PDF, it's already implemented in the demo project.

You need to integrate your code inside this method (in the classes mentioned earlier)

it's already implemented in the demo project.
it's already implemented in the demo project.
'it's already implemented in the demo project' is there git repo I can clone the demo project from?

You can get cordova plugin from RadaeePDF-Cordova Plugin
For example (Android), in RadaeePDFPlugin.java you can find that it implements RadaeePluginCallback.PDFReaderListener
