Flutter : How to create NEXT button from JSON data?

So, here is my detailDoaPage.dart that shown detailed item from a ListView.builder (based on my JSON local data) in previous page. In this detailed page, I want to create a button (Next button below) that change all attributes of this current data into next item. So the page isn't navigating, just changed the item inside it into the next data.

Anyone can help me to give me some advices for this problem? Here's my full code if you want to see it https://replit.com/join/nlmxirvq-nabilrei
