IconToggleButton

Component in Wear Material 3 Compose

Wear Material [IconToggleButton] is a filled icon toggle button which switches between primary colors and tonal colors depending on [checked] value, and offers a single slot for icon or image.

Set the size of the [IconToggleButton] with Modifier.[touchTargetAwareSize] to ensure that the background padding will correctly reach the edge of the minimum touch target. The recommended icon toggle button sizes are [IconToggleButtonDefaults.DefaultButtonSize], [IconToggleButtonDefaults.SmallButtonSize], [IconToggleButtonDefaults.LargeButtonSize] and [IconToggleButtonDefaults.ExtraLargeButtonSize].

Use [IconToggleButtonDefaults.iconSizeFor] to determine the icon size for a given [IconToggleButton] size, or refer to icon sizes, [IconToggleButtonDefaults.DefaultIconSize], [IconToggleButtonDefaults.LargeIconSize], [IconToggleButtonDefaults.ExtraLargeIconSize] directly.

[IconToggleButton] can be enabled or disabled. A disabled button will not respond to click events. When enabled, the checked and unchecked events are propagated by [onCheckedChange].

A simple icon toggle button using the default colors, animated when pressed.
