In Flutter, a StatelessWidget
is a type of widget that does not change over time. It is immutable, meaning that its properties and state are fixed after it is created. You use StatelessWidget
when the widget's appearance or behavior is determined entirely by its constructor parameters.
Easy Way to Define a StatelessWidget
Here’s a simple example:
Explanation:
- Inheritance: The widget class extends
StatelessWidget
. - Constructor: Pass any data the widget needs as constructor parameters.
- build() Method: This method is called to describe the widget's structure. It returns a widget tree that Flutter renders.
Use StatelessWidget
for parts of your UI that are constant and don’t need to react to user interaction or changes in state. If dynamic behavior is needed, consider using a StatefulWidget
instead.
