setFullExtent method

void setFullExtent(
  1. TKey key,
  2. double extent
)

Stores the measured full extent for a node.

Called by the render object after laying out a child.

Forwards to AnimationCoordinator.setFullExtent which carries the cross-source coordination logic (op-group member target resolve, captured-vs-natural target distinction, animation-status check). Invalidates the scroll prefix sum on extent change.

Implementation

void setFullExtent(TKey key, double extent) {
  final oldExtent = _anim.setFullExtent(key, extent);
  if (oldExtent != extent) {
    _scroll.invalidatePrefix();
  }
}
