/**
* <a href="https://material.io/components/sliders" class="external" target="_blank">Material Design slider</a>.
*
* Sliders allow users to make selections from a range of values.
*
* Sliders reflect a range of values along a bar, from which users may select a single value.
* They are ideal for adjusting settings such as volume, brightness, or applying image filters.
*
* ![Sliders image](https://developer.android.com/images/reference/androidx/compose/material/sliders.png)
*
* Use continuous sliders to allow users to make meaningful selections that don’t
* require a specific value:
*
* @sample androidx.compose.material.samples.SliderSample
*
* You can allow the user to choose only between predefined set of values by specifying the amount
* of steps between min and max values:
*
* @sample androidx.compose.material.samples.StepsSliderSample
*
* @param value current value of the Slider. If outside of [valueRange] provided, value will be
* coerced to this range.
* @param onValueChange lambda in which value should be updated
* @param modifier modifiers for the Slider layout
* @param enabled whether or not component is enabled and can be interacted with or not
* @param valueRange range of values that Slider value can take. Passed [value] will be coerced to
* this range
* @param steps if greater than 0, specifies the amounts of discrete values, evenly distributed
* between across the whole value range. If 0, slider will behave as a continuous slider and allow
* to choose any value from the range specified. Must not be negative.
* @param onValueChangeFinished lambda to be invoked when value change has ended. This callback
* shouldn't be used to update the slider value (use [onValueChange] for that), but rather to
* know when the user has completed selecting a new value by ending a drag or a click.
* @param interactionSource the [MutableInteractionSource] representing the stream of
* [Interaction]s for this Slider. You can create and pass in your own remembered
* [MutableInteractionSource] if you want to observe [Interaction]s and customize the
* appearance / behavior of this Slider in different [Interaction]s.
* @param colors [SliderColors] that will be used to determine the color of the Slider parts in
* different state. See [SliderDefaults.colors] to customize.
