How to accurately detect the number of reflowable screens in the Current Page

[ahmetfrkeken]

Hello, I'm working a reading application with reflowable EPUB support.

I'm trying to determine how many actual reflowable screen pages are present in the currently displayed page (locator.locations.position)

The goal is to check whether a specific text (e.g., from a Text.after highlight) appears on the same visible screen as the user's current reading position.

For example: if I'm on the 16th page (as determined by publication.positions()), I would like to calculate how many reflowable screen pages that logical page spans — which could be 1 on a tablet, but 2–3 on a phone with larger font settings.

I understand that this is currently not officially supported, but I really need to implement this functionality. I would greatly appreciate any guidance or suggestions you can offer.
