SlidableDismissal class

A widget that controls how the Slidable is dismissed.

The Slidable widget calls the onDismissed callback either after its size has collapsed to zero (if resizeDuration is non-null) or immediately after the slide animation (if resizeDuration is null). If the Slidable is a list item, it must have a key that distinguishes it from the other items and its onDismissed callback must remove the item from the list.

  • SlidableDrawerDismissal, which creates slide actions that are displayed like drawers while the item is dismissing.
