indexInFinalList property

int indexInFinalList

The index the dragged node should occupy in the final sibling list of parentKey after the move / reorder has completed.

• Cross-parent drops: pass directly to TreeController.moveNode as index.
• Same-parent drops: build a live sibling list with the dragged key removed and re-inserted at this index, then pass to TreeController.reorderChildren / TreeController.reorderRoots.

Implementation

final int indexInFinalList;
