Rotate an object

Unity Engine
1

I have a central object which is rotating around itself. I also got an arrow which is following the central rotation. If I click on the screen the rotation changes to the opposite direction.

I want the arrow object to flip around so it would point to the rotation direction. How can I do this?

My script so far:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CenterRotation : MonoBehaviour
{
    public int direction= 1;
    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        transform.Rotate(new Vector3(0, 0, direction), Space.Self);
    
        if (Input.GetMouseButtonDown(0))
        {
            {
                if (direction> 0)
                {
                    direction= -1;
                    Debug.Log("Changes direction!");
                }
                else
                {
                    direction= 1;
                    Debug.Log("Normal rotation!");
                }
            }
        }
    }
}

I attached pictures to the question just to be clear.

Thanks!

Can you set “flipY” or “flipX” on the SpriteRenderer for the arrow at the same time you change rotate direction?

Thanks for your answer. I could solved it be flipX.

Code:

public class SpriteFlipper : MonoBehaviour
{
   // variable to hold a reference to our SpriteRenderer component
   private SpriteRenderer mySpriteRenderer;
   // This function is called just one time by Unity the moment the component loads
   private void Awake()
   {
        // get a reference to the SpriteRenderer component on this gameObject
        mySpriteRenderer = GetComponent<SpriteRenderer>();
   }
   // This function is called by Unity every frame the component is enabled
   private void Update()
   {     
        // if the A key was pressed this frame
        if(Input.GetKeyDown(KeyCode.A))
        {
            // if the variable isn't empty (we have a reference to our SpriteRenderer
            if(mySpriteRenderer != null)
            {
                 // flip the sprite
                 mySpriteRenderer.flipX = true;
            }
        }
    }
}
