Creating save states

I want to create save states, but can't find out how.

Idea which ones I would like to implement:
I have data such as team names, people in the respective teams, and score of the individual teams. I would like to display these under a name in a list view on another screen. If I then click on the element in the list view, the data should be displayed.

Does anyone have any idea how I could do this?

What have you tried so far ? How do you save your data in lists? Post a screenshot of your data structure
