Module grid_layout 

What this design system paints on a grid layout.

Base owns the grid: where items sit, the drag, the resize, the keyboard and the layout arithmetic. Everything here is appearance — the gap, the motion items settle with, the drop placeholder, the resize grip, and how the dragged and the keyboard-selected items stand out.

grid_layout

Create a GridLayout wearing this design system: the theme’s medium spacing between items, its move motion, a dashed drop placeholder, a resize grip in each resizable item’s corner and a raised dragged item.
