Player is not flipping

i am trying to flip my player but in the tutorial he use 0.01f and when I try that my player gets really small on movement I want to fix this issue Script code:

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

public class PlayerMovement : MonoBehaviour { [SerializeField] private float speed; [SerializeField] private float jump;

 //Animator and Rigidbody References
 private Rigidbody2D body;
 private Animator anim;
 private bool grounded;

 private void Awake()
 {
     body = GetComponent<Rigidbody2D>();
     anim = GetComponent<Animator>();
 }
 private void Update()
 {
     float horizontalInput = Input.GetAxis("Horizontal");
     body.velocity = new Vector2(horizontalInput * speed, body.velocity.y);
     
     //Flip player movement left/right
     if(horizontalInput > 44f)
         transform.localScale = Vector3.one;
     else if(horizontalInput < -44f)
         transform.localScale = new Vector3(-1, 1, 1);

     if(Input.GetKey(KeyCode.Space) && grounded)
         Jump();
 
     //Set Animator parameters
     anim.SetBool("Run", horizontalInput !=0);
     anim.SetBool("Grounded", grounded);
 }

 private void Jump()
 {
     body.velocity = new Vector2(body.velocity.x, jump);
     anim.SetTrigger("jump");
     grounded = false;
 }

 private void OnCollisionEnter2D(Collision2D collision)
 {
     if(collision.gameObject.tag == "Ground")
         grounded = true;
 }

}
