Need Help Setting a Dynamic Leading Icon with JSON Path in a ListTile Widget

Hello, how can I set the "leading" icon in the ListTile widget from a variable (JSON path)? I want to place an avatar(api call) in that icon, and I need to use the SlidableActionWidget function for this. Can you please assist me with this?
