engine/overlay/tooltip_placement library

Classes

TooltipMultiPlacementDelegate: Multi-content placement: the primary tooltip plus every extra slot of a step, each placed by the shared placeTooltip core — a slot avoids the spotlighted targets AND the already-placed tooltips, so several tooltips around one target never overlap.
TooltipPlacementDelegate: Tooltip placement relative to its target.

placeTooltip({required Rect screen, required Rect hole, required TooltipPosition position, required Size size, required EdgeInsets safeArea, required List<Rect> avoid, double gap = _kGap}) → Offset: Pure placement core, shared by the single and multi delegates: the offset for a tooltip of size around hole, picking the best fitting side from position's order (preferred → mirrored → orthogonal; auto — by free space) and vetoing placements that overlap avoid or leave the safe rect.
