})

Creates an adaptive Slider based on the target platform, following Material design's Cross-platform guidelines.

Creates a CupertinoSlider if the target platform is iOS or macOS, creates a Material Design slider otherwise.

If a CupertinoSlider is created, the following parameters are ignored: secondaryTrackValue, label, inactiveColor, secondaryActiveColor, semanticFormatterCallback.

The target platform is based on the current Theme: ThemeData.platform.
