Flutter ListTile and ListView: When you start learning Flutter, two widgets often confuse beginners: ListTile  &  ListView . Both are used to display items in a list, but their purpose is different. Let’s break them down in a simple way. 🔹 What is ListTile in Flutter? ListTile is a ready-made widget used to show a single row (one item).
