You might be interested in my Native Checkbox widget:
https://github.com/tieniber/native-checkbox/releases/tag/1.0.0
It’s not on the marketplace (yet) but it’s there on GitHub. The widget provides 2 placeholders – one is rendered when the Boolean attribute is false, then other when it’s true. You can put an icon or image of your choice in there for a checked or unchecked status, and the value is toggled by a single tap.
