How to avoid overflow when I need to put a button (with navigate action) under a listview (whose children are created dynamically) ?

How to avoid overflow when I need to put a button (with navigate action) fixed to the bottom a page on the screen and underneath a listview (whose children are created dynamically) ?

I put the listview and the button inside a column. But since the listview keeps generating its children (cards with losts of info) dynamically, it creates an overflow at the bottom once a few cards are written in the collection.

It seems that putting a huge listview inside a column is just wrong.

How to display a button fixed to the bottom position of a screen under a (scrolling) listview?

Thanks!
