How to activate an action/function each time a page is brought up

I need an action or function to run each time this page (call it Page X) is navigated to.
What I found out is that the "On Page Load" action flow only runs for a few rounds (before Dispose() is called on the "host" page, after which the "On Page Load" action does not kick in).
Is it something possible within FlutterFlow or do I have to add in my own code to achieve this?
