This library provides a unique widget, WallLayout, rendering into a list children having different shapes.

There is two main classes: WallLayout and Stone.

A stone is a component defining its shape by a width and a height.

Wall Layout Widget #

Added to that, you can also define how many rows or column have the wall, if you want to create a responsive design.
