struct Transition

How a view animates as it appears and disappears.

Value animation (Animated<T>) covers a property changing on a node that stays put. A transition is the other half: the node itself arriving or leaving. Leaving is the hard direction — by the time a reconciler knows a child is gone, the view describing it no longer exists, so the node has to outlive its own removal. That is what FragmentNode.departingChildren is for, and it is why this touches the three reconcilers that drop nodes rather than living entirely in a modifier.
