What is a Widget in Flutter?
In Flutter, a widget describes a part of the user interface (UI). It could be a button, a text field, or even an entire screen. Widgets are classified into two main types:
- StatelessWidget: Doesn’t change its state once built. (e.g., Text, Icon, etc.)
- StatefulWidget: Can change its state over time. (e.g., Checkbox, Slider, etc.)
