ConditionalWrapper class
Allows you to conditionally wrap a child widget with one of two different wrappers based on a specified condition.
You can provide a wrapper to use when the condition is true and an optional falseWrapper to use when the condition is false.
This is useful for applying conditional styling or functionality to other widgets.
