SplitCheckboxButton

Component in Wear Material 3 Compose

The Wear Material [SplitCheckboxButton] offers slots and a specific layout for a label and secondaryLabel. The secondaryLabel is optional. The items are laid out with a column containing the two label slots and a Checkbox at the end.

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

A [SplitCheckboxButton] has two tappable areas, one tap area for the labels and another for the checkbox. The [onContainerClick] listener will be associated with the main body of the [SplitCheckboxButton] and the [onCheckedChange] listener associated with the checkbox area only.

Parameters

name	description
checked	Boolean flag indicating whether this button is currently checked.

toggleInteractionSource	an optional hoisted [MutableInteractionSource] for observing and emitting [Interaction]s for this button's "toggleable" tap area. 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.
containerInteractionSource	an optional hoisted [MutableInteractionSource] for observing and emitting [Interaction]s for this button's main body "clickable" tap area. 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.
containerClickLabel	Optional click label on the main body of the button for accessibility.
contentPadding	The spacing values to apply internally between the container and the content.
secondaryLabel	A slot for providing the button's secondary label. The contents are expected to be "start" aligned.
