RangeSlider

Range Sliders expand upon Slider using the same concepts but allow the user to select 2 values.

Common
@Composable
@ExperimentalMaterialApi
fun RangeSlider(
    value: ClosedFloatingPointRange<Float>,
    onValueChange: (ClosedFloatingPointRange<Float>) -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    valueRange: ClosedFloatingPointRange<Float> = 0f..1f,
    @IntRange(from = 0) steps: Int = 0,
    onValueChangeFinished: (() -> Unit)? = null,
    colors: SliderColors = SliderDefaults.colors(),
)

Parameters
value current values of the RangeSlider. If either value is outside of valueRange provided, it will be coerced to this range.
onValueChange lambda in which values should be updated
modifier modifiers for the Range Slider layout
enabled whether or not component is enabled and can we interacted with or not
valueRange range of values that Range Slider values can take. Passed value will be coerced to this range
steps if positive, specifies the amount of discrete allowable values between the endpoints of valueRange. For example, a range from 0 to 10 with 4 steps allows 4 values evenly distributed between 0 and 10 (i.e., 2, 4, 6, 8). If steps is 0, the slider will behave continuously and allow any value from the range. Must not be negative.
onValueChangeFinished lambda to be invoked when value change has ended. This callback shouldn't be used to update the range slider values (use onValueChange for that), but rather to know when the user has completed selecting a new value by ending a drag or a click.
colors SliderColors that will be used to determine the color of the Range Slider parts in different state. See SliderDefaults.colors to customize.

Code Examples

RangeSliderSample

@Composable
@OptIn(ExperimentalMaterialApi::class)
fun RangeSliderSample() {
    var sliderPosition by remember { mutableStateOf(0f..100f) }
    Column(modifier = Modifier.padding(horizontal = 16.dp)) {
        val rangeStart = "%.2f".format(sliderPosition.start)
        val rangeEnd = "%.2f".format(sliderPosition.endInclusive)
        Text(text = "$rangeStart .. $rangeEnd")
        RangeSlider(
            value = sliderPosition,
            onValueChange = { sliderPosition = it },
            valueRange = 0f..100f,
            onValueChangeFinished = {
                // launch some business logic update with the state you hold
                // viewModel.updateSelectedSliderValue(sliderPosition)
            },
        )
    }
}

StepRangeSliderSample

@Composable
@OptIn(ExperimentalMaterialApi::class)
fun StepRangeSliderSample() {
    var sliderPosition by remember { mutableStateOf(0f..100f) }
    Column(modifier = Modifier.padding(horizontal = 16.dp)) {
        val rangeStart = sliderPosition.start.roundToInt()
        val rangeEnd = sliderPosition.endInclusive.roundToInt()
        Text(text = "$rangeStart .. $rangeEnd")
        RangeSlider(
            value = sliderPosition,
            onValueChange = { sliderPosition = it },
            valueRange = 0f..100f,
            onValueChangeFinished = {
                // launch some business logic update with the state you hold
                // viewModel.updateSelectedSliderValue(sliderPosition)
            },
            // Only allow multiples of 10. Excluding the endpoints of `valueRange`,
            // there are 9 steps (10, 20, ..., 90).
            steps = 9,
            colors =
                SliderDefaults.colors(
                    thumbColor = MaterialTheme.colors.secondary,
                    activeTrackColor = MaterialTheme.colors.secondary,
                ),
        )
    }
}
