@Composable
fun InlineSlider(
    value: Int,
    onValueChange: (Int) -> Unit,
    valueProgression: IntProgression,
    decreaseIcon: @Composable () -> Unit,
    increaseIcon: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    segmented: Boolean = valueProgression.stepsNumber() <= 8,
    colors: InlineSliderColors = InlineSliderDefaults.colors()
): Unit

InlineSlider allows users to make a selection from a range of values. The range of selections is shown as a bar between the minimum and maximum values of the range, from which users may select a single value. InlineSlider is ideal for adjusting settings such as volume or brightness.

Value can be increased and decreased by clicking on the increase and decrease buttons, located accordingly to the start and end of the control. Buttons can have custom icons - decreaseIcon and increaseIcon.

The bar in the middle of control can have separators if segmented flag is set to true. A number of steps is calculated as the difference between max and min values of valueProgression divided by valueProgression.step - 1. For example, with a range of 100..120 and a step 5, number of steps will be (120-100)/ 5 - 1 = 3. Steps are 100(first), 105, 110, 115, 120(last)

If valueProgression range is not equally divisible by valueProgression.step, then valueProgression.last will be adjusted to the closest divisible value in the range. For example, 1..13 range and a step = 5, steps will be 1(first) , 6 , 11(last)

A continuous non-segmented slider sample:

import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.wear.compose.material.Icon
import androidx.wear.compose.material.InlineSlider
import androidx.wear.compose.material.InlineSliderDefaults

var value by remember { mutableStateOf(4) }
InlineSlider(
    value = value,
    onValueChange = { value = it },
    increaseIcon = { Icon(InlineSliderDefaults.Increase, "Increase") },
    decreaseIcon = { Icon(InlineSliderDefaults.Decrease, "Decrease") },
    valueProgression = 0..10,
    segmented = false,
)

A segmented slider sample:

import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.wear.compose.material.Icon
import androidx.wear.compose.material.InlineSlider
import androidx.wear.compose.material.InlineSliderDefaults

var value by remember { mutableStateOf(2f) }
InlineSlider(
    value = value,
    onValueChange = { value = it },
    increaseIcon = { Icon(InlineSliderDefaults.Increase, "Increase") },
    decreaseIcon = { Icon(InlineSliderDefaults.Decrease, "Decrease") },
    valueRange = 1f..4f,
    steps = 7,
    segmented = true,
)

Parameters
`value: Int`	Current value of the Slider. If outside of `valueProgression` provided, value will be coerced to this range.
`onValueChange: (Int) -> Unit`	Lambda in which value should be updated
`valueProgression: IntProgression`	Progression of values that Slider value can take. Consists of rangeStart, rangeEnd and step. Range will be equally divided by step size
`decreaseIcon: @Composable () -> Unit`	A slot for an icon which is placed on the decrease (start) button
`increaseIcon: @Composable () -> Unit`	A slot for an icon which is placed on the increase (end) button
`modifier: Modifier = Modifier`	Modifiers for the Slider layout
`enabled: Boolean = true`	Controls the enabled state of the slider. When `false`, this slider will not be clickable
`segmented: Boolean = valueProgression.stepsNumber() <= 8`	A boolean value which specifies whether a bar will be split into segments or not. Recommendation is while using this flag do not have more than 8 steps as it might affect user experience. By default true if number of steps is <=8.
`colors: InlineSliderColors = InlineSliderDefaults.colors()`	`InlineSliderColors` that will be used to resolve the background and content color for this slider in different states

@Composable
fun InlineSlider(
    value: Float,
    onValueChange: (Float) -> Unit,
    steps: Int,
    decreaseIcon: @Composable () -> Unit,
    increaseIcon: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    enabled: Boolean = true,
    valueRange: ClosedFloatingPointRange<Float> = 0f..(steps + 1).toFloat(),
    segmented: Boolean = steps <= 8,
    colors: InlineSliderColors = InlineSliderDefaults.colors()
): Unit

The bar in the middle of control can have separators if segmented flag is set to true. A single step value is calculated as the difference between min and max values of valueRange divided by steps + 1 value.

Parameters
`value: Float`	Current value of the Slider. If outside of `valueRange` provided, value will be coerced to this range.
`onValueChange: (Float) -> Unit`	Lambda in which value should be updated
`steps: Int`	Specifies the number of discrete values, excluding min and max values, evenly distributed across the whole value range. Must not be negative. If 0, slider will have only min and max values and no steps in between
`decreaseIcon: @Composable () -> Unit`	A slot for an icon which is placed on the decrease (start) button
`increaseIcon: @Composable () -> Unit`	A slot for an icon which is placed on the increase (end) button
`modifier: Modifier = Modifier`	Modifiers for the Slider layout
`enabled: Boolean = true`	Controls the enabled state of the slider. When `false`, this slider will not be clickable
`valueRange: ClosedFloatingPointRange<Float> = 0f..(steps + 1).toFloat()`	Range of values that Slider value can take. Passed `value` will be coerced to this range
`segmented: Boolean = steps <= 8`	A boolean value which specifies whether a bar will be split into segments or not. Recommendation is while using this flag do not have more than 8 `steps` as it might affect user experience. By default true if number of `steps` is <=8.
`colors: InlineSliderColors = InlineSliderDefaults.colors()`	`InlineSliderColors` that will be used to resolve the background and content color for this slider in different states
