The core of Flutter’s layout mechanism is widgets. In Flutter, almost everything is a widget—even layout models are widgets. The images, icons, and text that you see in a Flutter app are all widgets. But things you don’t see are also widgets, such as the rows, columns, and grids that arrange, constrain, and align the visible widgets.

A StatelessWidget will never rebuild by itself (but can from external events). A StatefulWidget can. That is the golden rule.

Stateless only means that all of its properties are immutable and that the only way to change them is to create a new instance of that widget.

This project is a starting point for a Flutter application.
