ToggleButton

Component in Wear Material Compose

Wear Material [ToggleButton] that offers a single slot to take any content (text, icon or image).

The [ToggleButton] is circular in shape and defaults to size [ToggleButtonDefaults.DefaultToggleButtonSize] or [ToggleButtonDefaults.SmallToggleButtonSize]. Icon content should be of size [ToggleButtonDefaults.DefaultIconSize] or [ToggleButtonDefaults.SmallIconSize] respectively.

The recommended set of checked and unchecked [ToggleButtonColors] can be obtained from [ToggleButtonDefaults.toggleButtonColors], which defaults to checked colors being a solid background of [Colors.primary] with content color of [Colors.onPrimary] and unchecked colors being a solid background of [Colors.surface] with content color of [Colors.onSurface].

[ToggleButton]s can be enabled or disabled. A disabled toggle button will not respond to click events.

Parameters

name	description
checked	Boolean flag indicating whether this toggle button is currently checked.
onCheckedChange	Callback to be invoked when this toggle button is clicked.
modifier	Modifier to be applied to the toggle button.
enabled	Controls the enabled state of the toggle button. When false, this toggle button will not be clickable.
colors	[ToggleButtonColors] that will be used to resolve the background and content color for this toggle button. See [ToggleButtonDefaults.toggleButtonColors].
interactionSource	The [MutableInteractionSource] representing the stream of [Interaction]s for this toggle button. You can create and pass in your own remembered [MutableInteractionSource] if you want to observe [Interaction]s and customize the appearance / behavior of this ToggleButton in different [Interaction]s.
content	The icon, image or text to be drawn inside the toggle button.
