onCapacityGrew property

void Function(int newCapacity)? onCapacityGrew

Optional callback fired when _ensureDenseCapacity reallocates the per-nid arrays. The argument is the new capacity, in slots. The controller uses this to grow its own per-nid arrays (_visibleSubtreeSizeByNid, the order buffer's reverse index) in lockstep.

Implementation

final void Function(int newCapacity)? onCapacityGrew;
