CupertinoSlidingSegmentedControl is an iOS-styled segmented control widget, that has a small animation when switching between different values. It is very very similar to CupertinoSegmentedControl, it just has 2–3 other properties (Read more about CupertinoSegmentedControl here)

As always, let’s first take a look at the properties.

The most important property is the children property of type Map<T, Widget>. You will ask yourself now, why is it a map? Well, I won’t explain it now, but when we look at a code example later, you will understand why it is a map :)

groupValue represents the currently segmented control. And of course, there is onValueChanged of type ValueChanged<T>.
