SmallExtendedFloatingActionButton

Composable Component

Extended FABs help people take primary actions. They're wider than FABs to accommodate a text label and larger target area.

Common
@ExperimentalMaterial3ExpressiveApi
@Composable
fun SmallExtendedFloatingActionButton(
    onClick: () -> Unit,
    modifier: Modifier = Modifier,
    shape: Shape = FloatingActionButtonDefaults.smallExtendedFabShape,
    containerColor: Color = FloatingActionButtonDefaults.containerColor,
    contentColor: Color = contentColorFor(containerColor),
    elevation: FloatingActionButtonElevation = FloatingActionButtonDefaults.elevation(),
    interactionSource: MutableInteractionSource? = null,
    content: @Composable RowScope.() -> Unit,
)

Parameters

onClickcalled when this FAB is clicked
modifierthe Modifier to be applied to this FAB
shapedefines the shape of this FAB's container and shadow (when using elevation)
containerColorthe color used for the background of this FAB. Use Color.Transparent to have no color.
contentColorthe preferred color for content inside this FAB. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
elevationFloatingActionButtonElevation used to resolve the elevation for this FAB in different states. This controls the size of the shadow below the FAB. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See also: Surface.
interactionSourcean optional hoisted MutableInteractionSource for observing and emitting Interactions for this FAB. You can use this to change the FAB's appearance or preview the FAB in different states. Note that if null is provided, interactions will still happen internally.
contentthe content of this FAB, typically a Text label

Parameters

textlabel displayed inside this FAB
iconicon for this FAB, typically an Icon
onClickcalled when this FAB is clicked
modifierthe Modifier to be applied to this FAB
expandedcontrols the expansion state of this FAB. In an expanded state, the FAB will show both the icon and text. In a collapsed state, the FAB will show only the icon.
shapedefines the shape of this FAB's container and shadow (when using elevation)
containerColorthe color used for the background of this FAB. Use Color.Transparent to have no color.
contentColorthe preferred color for content inside this FAB. Defaults to either the matching content color for containerColor, or to the current LocalContentColor if containerColor is not a color from the theme.
elevationFloatingActionButtonElevation used to resolve the elevation for this FAB in different states. This controls the size of the shadow below the FAB. Additionally, when the container color is ColorScheme.surface, this controls the amount of primary color applied as an overlay. See also: Surface.
interactionSourcean optional hoisted MutableInteractionSource for observing and emitting Interactions for this FAB. You can use this to change the FAB's appearance or preview the FAB in different states. Note that if null is provided, interactions will still happen internally.
