Page Indicator || Struggling to figure it out

Spent the past 3 days all-day and night trying to figure this out.
Currently slumped in my chair mentally exhausted.

I've been attempting to get PageView to work alike to a user choosing from a handful of preset options on the screen, and then the next page showing based in accordance with their preset selection. (Have attached).

Initially I tried to dynamically have the buttons change in accordance with the user's options. Failed miserably as I can't see to get it.

So now I tried to create a separate page for the next set of preset options, and instead, when you go to the next page, it shows the Page1 of the next page, rather than page 2.

Is there a way to make PageView's page-indicator animation work without needing the other two pages, as when I remove the other two pages, the paging indicators are removed to.

I just want to make the paging indicator remain whilst a user gets to click through the buttons, and the according buttons show up depending on the button choice selected.

Any help would be greatly appreciated. I am exhausted haha ๐Ÿ˜‚
