rememberExpandableStateMapping
Composable Function
Android
@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 ExpandableState
s ExpandableState
s 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 AnimationSpec to use when showing the extra information. |
collapseAnimationSpec | The AnimationSpec to use when hiding the extra information. |
