Keeping TOC layers unchecked on first load in ArcGIS JavaScript API

Question

I am using NLiu's TOC widget for displaying the layers. It is working perfectly, however, I wanted to keep all layers unchecked when it is loading on the browser (for performance reason). I tried to find a way on its javascript files but not succeed.

Any clue to do so?

将图层的可见图层设置为无：
