selectedPickerTypeColor property
The color on the thumb of the slider that shows the selected picker type.
If not defined, it defaults to Color(0xFFFFFFFF)
(white) in light
theme and to Color(0xFF636366)
in dark theme, which are the defaults
for the used CupertinoSlidingSegmentedControl.
If you give it a custom color, the color picker will automatically adjust the text color on the selected thumb for best legible text contrast.
