How to retrieve "Site Sizes" from my custom node source code

@hotNipi

Tried it and it's working very well

if (ui === undefined) {
	ui = RED.require("node-red-dashboard")(RED);
}			
console.log("sizes -> ",ui.getSizes());
console.log("theme -> ",ui.getTheme());

@dceejay, is this going to work inside a function node? It could answer the question I raised in Custom icon color in dashboard switch widget.
