SwitchButton

Component in Wear Material 3 Compose

The Wear Material [SwitchButton] offers three slots and a specific layout for an icon, a label, and a secondaryLabel. The icon and secondaryLabel are optional. The items are laid out in a row with the optional icon at the start and a column containing the two label slots in the middle.

The [SwitchButton] is Stadium shaped. The label should take no more than 3 lines of text. The secondary label should take no more than 2 lines of text. With localisation and/or large font sizes, the [SwitchButton] height adjusts to accommodate the contents. The label and secondary label are start aligned by default.

You can use this to change the button's appearance or preview the button in different states. Note that if null is provided, interactions will still happen internally.
