Create animation clip without "using UnityEditor"

Hi . In my 2D game I create the animations for many characters from their atlases using this code in my script . But I can't use UnityEditor in Build so I must find another way to do it . So far I haven't found a way . Please help !

 using UnityEditor;

 void createRunAnim(){
         EditorCurveBinding curveBinding = new EditorCurveBinding();
         curveBinding.type = typeof(SpriteRenderer);
         curveBinding.path = "";
         curveBinding.propertyName = "m_Sprite";
         
         ObjectReferenceKeyframe[] runFrames = new ObjectReferenceKeyframe[6];
         for(int i=3 ; i<= 8; i++){
             runFrames[i-3] = new ObjectReferenceKeyframe();
             runFrames[i-3].value = animalArray[i];
             runFrames[i-3].time = (i-3);
         
         }
 
         AnimationUtility.SetObjectReferenceCurve(run,curveBinding,runFrames);
     }
