C# Obj_Image Flip according to VJ facing direction

Greetings Guise,

I'm currently creating 2D side scrolling game with Fish Behavior controlling via Virtual Joystick. So my fish facing to the right for which is Default. What I can't do is that when my Virtual Joystick facing to the left, then my fish face to the left.

I've tried a lot of research but It didn't work. Or prolly is my programming skills not that good after-all. T_T

Below codes work well for moving and when moving to the left you will see a upside down Fish haha!

 public float moveForce = 5, boostMultiplier = 2;
     public float rotSpeed = 5f;
     Rigidbody2D myBody;
 
     void Start () 
     {
         myBody = this.GetComponent<Rigidbody2D>();
     }
 
     void FixedUpdate () 
     {
         Vector2 moveVec = new Vector2(CrossPlatformInputManager.GetAxis("Horizontal"),CrossPlatformInputManager.GetAxis ("Vertical"))* moveForce;
         bool isBoosting = CrossPlatformInputManager.GetButton("Boost");
         Debug.Log (isBoosting ? boostMultiplier : 1);
         myBody.AddForce(moveVec * (isBoosting ? boostMultiplier : 1));
 
 
         if (moveVec != Vector2.zero) 
         {
             float angle = Mathf.Atan2(moveVec.y, moveVec.x) * Mathf.Rad2Deg;
             transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
         
         
 
 
 //            
         }

Note : The Virtual Joystick Code is from the free Standard Assets in Unity.

I found this code but i Don't know where to put this flip function. It didn't work well

 //            Vector3 theScale = transform.localScale;
 //            theScale.x *= -1;
 //            transform.localScale = theScale

I would kindly appreciate any kind ones help me ^_^. Thank you. Peace!
