CupertinoSegmentedControl

CupertinoSegmentedControl is an iOS-styled widget that displays the widgets provided in a Map of children in a horizontal list. According to the Flutter documentation, it is “used to select between a number of mutually exclusive options”.

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>.

Okay, now we want to customize our widget a bit.

You can set the color of the selected element with selectedColor. Of course, you can set the color of the unselected ones with unselectedColor. When the user temporarily interacts with the widget, the area where he clicks will be highlighted with the pressedColor. And the last color we want to discuss is borderColor.

Great, these were all the important properties you need to know. Oh, wait, no ;) padding is missing :)

Let’s finally take a look at a code example:
