isPendingDeletion method

bool isPendingDeletion(
  1. TKey key
)

Whether key is pending deletion — present in the structural maps but animating out and scheduled for purge once the animation settles.

Drop-target resolution should skip pending-deletion rows: they are visually vanishing and cannot be valid reorder targets. Also used as the predicate for filtering rootKeys / getChildren down to the live sets accepted by reorderRoots / reorderChildren.

Implementation

bool isPendingDeletion(TKey key) => _isPendingDeletion(key);
