getSlideDelta method

double getSlideDelta(
  1. TKey key
)

Current slide delta for key in scroll-space y, or 0.0 if the node is not currently sliding. Read by RenderSliverTree.paint, RenderSliverTree.applyPaintTransform, and the hit-test path on every frame (no caching — staleness-safe under tick-without-paint).

Implementation

double getSlideDelta(TKey key) => _slide.deltaForKey(key);
