Ah, but the right screenshot does have ListTile Widgets. However, they are not defined in the screenshot. They are defined elsewhere in a different class:
Defining them elsewhere makes the code in the screenshot smaller and easier to read. For example, con.widget.optimistic, is defined under the folder, controller, in the file, stock_home.dart and accessed with the following getter:
Widget get optimistic => listTiles.optimistic;
This approach makes for larger projects with complicated user interfaces a little bit more manageable.
