Stateless vs. Stateful Widgets
Understand the core differences between StatelessWidget and StatefulWidget, learning when and how to use each for building dynamic UIs.
Widgets: The Building Blocks
Flutter UIs are built entirely from widgets. Think of them as LEGO bricks! Everything you see on screen – text, buttons, even layout containers — is a widget.
Widgets describe how your app's UI should look given its current configuration and state. There are two main types of widgets you'll encounter:
- StatelessWidget
- StatefulWidget
StatelessWidget: Static UI
A StatelessWidget is a widget that does not change its appearance or behavior over time. Once it's built, it stays the same.
- It doesn't have any internal "state" to manage.
- Its properties are immutable (cannot be changed after creation).
- It's perfect for displaying static content like text, icons, or images that don't need to react to user input or data changes.
