I have a view that's receiving an ID value from the previous view. I need to also take that ID value and pass it into an ObservableObject so that I can run a Firestore query on that ID. I'm at a loss as to how to grab that ID for my ObservableObject.

import SwiftUI
import Firebase

struct ItemsView: View {
   var itemName: String
   var itemID: String
   @ObservedObject var items = getItemsData()
    // ....etc
    }

class getItemsData() {
   @Published var data = [items]()
   init() {
      let db = Firestore.firestore()
      db.collection("items").whreField("itemID", isEqualTo: "THIS IS WHERE I NEED TO PASS THE VALUE OF itemID").addSnopshotListenser

So in the query call, I need to call the ItemID value to query based on that value that's defined at the top of the view.

}
    }
class ItemsGetter {
   @Published var data = [items]()
   func get(itemID:String) {
      let db = Firestore.firestore()
