Check all properties of null of an object using reflection [kotlin]

 inline fun <reified T: Any>notNullProperties(data: T, callBack :(list: List<String>)->Unit){  
   val allNullData = mutableListOf<String>()  
   for (prop in T::class.memberProperties) {  
     if ( prop.get(data) == null){  
       allNullData.add(prop.name)  
     }  
   }  
   callBack.invoke(allNullData)  
 }  

• Use case      

  val changePassword = ChangePassword()  
         notNullProperties(changePassword){  
           if (it.isEmpty()){  
             println("not null")  
           }else{  
             println("Null : $it")  
           }  
         }
