Composable Function

@Composable
@ExperimentalWearFoundationApi
public fun <T> rememberExpandableStateMapping(
    initiallyExpanded: (key: T) -> Boolean = { false },
    expandAnimationSpec: AnimationSpec<Float> = ExpandableItemsDefaults.expandAnimationSpec,
    collapseAnimationSpec: AnimationSpec<Float> = ExpandableItemsDefaults.collapseAnimationSpec,
): ExpandableStateMapping<T>
Create and remember a mapping from keys to ExpandableStates ExpandableStates can be
requested by key, and we will created with the parameters given here when a mapping didn't exist
before. This is mainly useful when you want to have a variable number of expandables, that can
change at runtime (for example, elements on a ScalingLazyColumn)
Parameters
| initiallyExpanded | A function to compute the initial state given the key. | 
| expandAnimationSpec | The AnimationSpecto use when showing the extra information. | 
| collapseAnimationSpec | The AnimationSpecto use when hiding the extra information. |
