CheckboxButton

Android

Component in Wear Material 3 Compose

The Wear Material [CheckboxButton] 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 [CheckboxButton] 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 [CheckboxButton] height adjusts to accommodate the contents. The label and secondary label are start aligned by default.
