@Composable
fun SearchBar(
    state: SearchBarState,
    inputField: @Composable () -> Unit,
    modifier: Modifier = Modifier,
    shape: Shape = SearchBarDefaults.inputFieldShape,
    colors: SearchBarColors = SearchBarDefaults.colors(),
    tonalElevation: Dp = SearchBarDefaults.TonalElevation,
    shadowElevation: Dp = SearchBarDefaults.ShadowElevation,
)

Parameters

state the state of the search bar. This state should also be passed to the inputField and the expanded search bar.
inputField the input field of this search bar that allows entering a query, typically a SearchBarDefaults.InputField.
modifier the Modifier to be applied to this search bar when collapsed.
shape the shape of this search bar when collapsed.
colors SearchBarColors that will be used to resolve the colors used for this search bar in different states. See SearchBarDefaults.colors.
tonalElevation when SearchBarColors.containerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
shadowElevation the elevation for the shadow below this search bar.

    shadowElevation: Dp = SearchBarDefaults.ShadowElevation,
    windowInsets: WindowInsets = SearchBarDefaults.windowInsets,
    content: @Composable ColumnScope.() -> Unit,
)

Parameters

inputField the input field of this search bar that allows entering a query, typically a SearchBarDefaults.InputField.
expanded whether this search bar is expanded and showing search results.
onExpandedChange the callback to be invoked when this search bar's expanded state is changed.
modifier the Modifier to be applied to this search bar.
shape the shape of this search bar when it is not expanded. When expanded, the shape will always be SearchBarDefaults.fullScreenShape.
colors SearchBarColors that will be used to resolve the colors used for this search bar in different states. See SearchBarDefaults.colors.
tonalElevation when SearchBarColors.containerColor is ColorScheme.surface, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: Surface.
shadowElevation the elevation for the shadow below this search bar
windowInsets the window insets that this search bar will respect
content the content of this search bar to display search results below the inputField.
