The Slider is used to allow users to make selections from a range of values.
NativeBase exports 4 slider-related components:
Slider: The wrapper that provides context and functionality for all children.
Slider.Track: The empty part of the slider that shows the track.
Slider.FilledTrack: The filled part of the slider.
Slider.Thumb: The handle that is used to change the slider value.
