[V1] Checkbox with checked/unchecked icon

[paul]

Until V 0.17 is was possible to specify e.g. checked-icon=“lock”
unchecked-icon=“lock_open” inside a checkbox.
By doing so the default visualization of the checkbox was replaced by the 2 icons.

What’s the way to go in V1 to accomplish this?

Interested in this as well - we used circles as the icons.
