Checkbox

This component is basically just a wrapper for <input type="checkbox" />. You'll probably want to use it along with a <label>. You also might prefer to use RFUI's FormField to wrap it.
Source code
import { Checkbox } from "rfui-package";

See the docs for rest parameters. For Checkbox, you could pass anything you normally would pass to <input type="checkbox" /> because the return value looks something like this:
<input
  type="checkbox"
  className={className}
  {...rest}
/>
