Flutter Assigning QuerySnapshot to Map<dynamic, dynamic> - firebase

Question

I am trying to fetch some menu item details such as menu name, slogan text icon, and verify data from firebase firestore using flutter but in the services of database getMenus() function, I am facing an error.
I have the following class model
import 'dart:convert';
MenuModel medicalTestModelFromJson(String str) => MenuModel.fromJson(json.decode(str));
String medicalTestModelToJson(MenuModel data) => json.encode(data.toJson());
class MenuModel {
MenuModel({
required this.title,
required this.slogan,
required this.icon,
required this.verify,
});
String title;
String slogan;
String icon;
bool verify;
factory MenuModel.fromJson(Map<String, dynamic> json) => MenuModel(
title: json["title"],
slogan: json["slogan"],
icon: json["icon"],
verify: json["verify"],
);
Map<String, dynamic> toJson() => {
"title": title,
"slogan": slogan,
"icon": icon,
"verify": verify,
};
}
And the following is the menu collection services from firebase firestore
class MenuServices{
static Future<List<MenuModel>> getMenus() async {
QuerySnapshot menuSnapshot = await FirebaseFirestore.instance.collection('homeItems').where("verify", isEqualTo: true).get();
List<MenuModel> menus =[];
Map<dynamic, dynamic> values = menuSnapshot.docs; //(***My Error is Exactly in this line which menuSnapshot.docs is not recognizing***)
values.forEach((key, values) {
menus.add(MenuModel.fromJson(values));
});
return menus;
}
}
And the error is
A value of type 'List<QueryDocumentSnapshot<Map<String, dynamic>>>' can't be assigned to a variable of type 'Map<dynamic, dynamic>

Answer 1

Change it to this:
class MenuServices{
static Future<List<MenuModel>> getMenus() async {
QuerySnapshot menuSnapshot = await FirebaseFirestore.instance.collection('homeItems').where("verify", isEqualTo: true).get();
List<MenuModel> menus = menuSnapshot.docs.map(
(e)=> MenuModel.fromJson(e.data() as Map<String, dynamic>)).toList();
return menus;
}
}

Answer 2

I used this and it worked:
void getLeituras(QuerySnapshot snapshot){
List leituras = [];
Leitura leitura;
snapshot.docs.forEach((e) {
leitura = Leitura();
leitura = Leitura.fromJson(e.data as Map<String, dynamic>);
leituras.add(leitura);
});
}
