handleMovingFinished method

ReorderableEntity handleMovingFinished({ required ReorderableEntity reorderableEntity, })

Updates offset and order id of reorderableEntity faded in.

Should be called when the fade in was finished. Then the original offset and orderId are overwritten with the updated values of the entity.

If the maps already hold another position for the child, the current entity is returned and the maps stay unchanged.

Implementation

ReorderableEntity handleMovingFinished({
  required ReorderableEntity reorderableEntity,
}) {
  // A swap while dragging can move this child in the frame its move finishes,
  // before it is rebuilt. Applying the old position would remove the child
  // the swap moved there from the maps.
  final currentEntity = childrenKeyMap[reorderableEntity.key.value];
  if (currentEntity != null &&
      currentEntity.updatedOrderId != reorderableEntity.updatedOrderId) {
    return currentEntity;
  }

  final updatedEntity = reorderableEntity.positionUpdated();
  _updateMaps(reorderableEntity: updatedEntity);

  return updatedEntity;
}
