react.memo 를 했는데 안되요 오타도 아닌데 왜그럴까요?

import React from 'react'

    const List = React.memo (({
        id, title, completed, todoData, setTodoData, provided, snapshot
    }) =>{

    console.log('List is Rendering');

    const handleClick =(id) => {
        let newTodoData = todoData.filter((data)=> data.id !== id)
        console.log ('newTodoData', newTodoData);
        //this.setState({todoData: newTodoData});
        setTodoData(newTodoData);
        };

    const handleCompleteChange = (id) => {
        let newTodoData = todoData.map(data => {
            if(data.id === id){
            data.completed = !data.completed;
            }
            return data;
        })
        //this.setState({ todoData : newTodoData})
        setTodoData(newTodoData);
    };

  return (
    <div key={id} {...provided.draggableProps} ref={provided.innerRef} {...provided.dragHandleProps}
    className={`${snapshot.isDragging ? "bg-gray-400" : "bg-gray-100"} flex items-center justify-between w-full px-4 py-1 my-2 text-gray-600 bg-gray-100 rounded`}>

        <div className='item-center'>
            <input 
            type="checkbox" 
            defaultChecked={completed}
            onChange={() => handleCompleteChange(id)}/>
            <span className={completed ? 'line-through' : undefined}>{title}</span>
        </div>
            <div className='item-center'>
                <button className="px-4 py-2 float-right" onClick={()=> handleClick(id)}>x</button>
            </div>

    </div>
  )
});
