flutter_wall_layout - Layout child having different shape into a vertical or horizontal list #
This library provides a unique widget, WallLayout, rendering into a list children having different shapes.
There is two main classes: WallLayout and Stone.
- A wall is composed by a set of stones, arranged in a certain way.
- A stone is a component defining its shape by a width and a height.

This component has been inspired by the ListView widget, in which you can choose scroll direction and the way. Added to that, you can also define how many rows or column have the wall, if you want to create a responsive design.
WallLayout(
stones: _buildStonesList(),
layersCount: 3,
scrollDirection: Axis.vertical,
reverse: false,
);
