ListTile widget in Flutter - UI Render Trace

Component - ListTile widget

The ListTile widget in Flutter is a simple way to create a fixed-height row that can contain a title, subtitle, leading icon or image, and a trailing icon or widget. It is commonly used in lists to display related information in a clean, organized way.

Widget Tree

Scaffold
├─ AppBar
└─ Body
   └─ ListView
      └─ ListTile

The Scaffold provides the basic visual layout with an AppBar on top. The body contains a ListView which can scroll vertically. Inside the ListView, each item is a ListTile widget that displays a row with an icon on the left (leading), a title and subtitle in the center, and an icon on the right (trailing).
