dragProxyGeometry property

({double grabDy, double rowExtent})? get dragProxyGeometry

The active session's grab geometry: the pointer's dy within the dragged row at start, and that row's extent. null when idle. Presentation consumers position the proxy at pointer - grabDy.

Implementation

({double grabDy, double rowExtent})? get dragProxyGeometry {
  final session = _session;
  if (session == null) {
    return null;
  }
  return (
    grabDy: session.probe.grabDy,
    rowExtent: session.probe.grabRowExtent,
  );
}
