Flutter ListView to do a http request as the list scrolls to 70% of the viewport height

Question

How do I make a ListView do http requests when it has scrolled every 70% of the viewport?

As I scroll the list, the ListView should make consecutive http requests to fetch data from the api as soon as it reaches a certain height in the scrollable viewport.
