/**
* When you programmatically add or remove handles to a node or update a node's
* handle position, you need to let React Flow know about it using this hook. This
* will update the internal dimensions of the node and properly reposition handles
* on the canvas if necessary.
*
* @public
* @returns Use this function to tell React Flow to update the internal state of one or more nodes
* that you have changed programmatically.
*
* @example
* ```jsx
*import { useCallback, useState } from 'react';
*import { Handle, useUpdateNodeInternals } from '@xyflow/react';
*
*export default function RandomHandleNode({ id }) {
* const updateNodeInternals = useUpdateNodeInternals();
* const [handleCount, setHandleCount] = useState(0);
* const randomizeHandleCount = useCallback(() => {
* setHandleCount(Math.floor(Math.random() * 10));
* updateNodeInternals(id);
* }, [id, updateNodeInternals]);
*
* return (
* <>
* {Array.from({ length: handleCount }).map((_, index) => (
*
There are {handleCount} handles on this node.
