Get the boolean from the child to the parents

hai,

i want to create drag & drop system,

and i want if every child (Barang) is true, the Parent (Winner) recieve boolean true

this is the "Slot_Recieve" script

 public string namabar;
     public bool barang = false;
 
     void Update()
     {
         if (transform.childCount > 0)
         {
             barang = transform.FindChild(namabar);
             if (barang)
             {
                 Debug.Log("Benar");
                 barang = true;
               //  Debug.Break();
             }
             else
             {
                Debug.Log("Salah");
                barang = false;
                //Debug.Break();
             }
         }
 
     }

and this is the "TrueAll" Script

 public bool Winner;
     
     void Start()
     {
         Winner = gameObject.GetComponentInChildren<Slot_Recieve>().barang;
     }
 
     void Update()
     {
         if (Winner)
         {
             Winner = true;
             Debug.Log("win");
         }
     }
