Widget

Definitions

1. A reusable UI element — button, text field, slider, dropdown — that encapsulates both appearance and behavior. In Flutter, everything is a widget; in desktop toolkits like Qt or GTK, widgets are the building blocks of the interface.

   In plain English: A building block of a graphical interface — any interactive or visual element like a button, text box, or slider.

   Example: "In Flutter, even padding is a widget. It's widgets all the way down."
