CupertinoSlider is an iOS-styled slider, who would have thought it ;)

Okay, so let’s take a look at it:

First, we want to discuss the values that the user can choose from. There is the min and max property, both of type double, that determine the minimum and maximum value of the slider. There is also division, so the number of discrete divisions. Let’s say your min value is 0, your max value is 10, and your division is set to 5. Then the user can select 0, 2, 4, 6, 8, or 10, because there now there are 5 options (minimum value doesn’t count) to choose from.
