How to add different images in a dropdown in flutter - flutter

Question

I tried to do a dropdown menu like this:
I found this exemple in stackoverflow to add image in dropdown but currently it's a list and I don't know how add different images
import 'package:flutter/material.dart';
class Test extends StatefulWidget {
#override
_TestState createState() => new _TestState();
}
class _TestState extends State<Test> {
var _img = new
Image.network("https://upload.wikimedia.org/wikipedia/commons/thumb/8/89/TUCPamplona10.svg/500px-TUCPamplona10.svg.png");
#override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(title: new Text("Test Drop"),),
body: new Center(
child: new Container (
height: 50.0,
child:new DropdownButton(
items: new List.generate(10, (int index){
return new DropdownMenuItem(child: new Container(
padding: const EdgeInsets.only(bottom: 5.0),
height: 100.0,
child: new Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
_img,
new Text("Under 10")
],
),
));
})
, onChanged: null),),
),
);
}
}

I did it with JSON. you can call multiple values inside dropdown.
import "package:flutter/material.dart";
import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;
class TestApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<TestApp> {
String _mySelection;
final String url = "http://webmyls.com/php/getdata.php";
List data = List(); //edited line
Future<String> getSWData() async {
var res = await http
.get(Uri.encodeFull(url), headers: {"Accept": "application/json"});
var resBody = json.decode(res.body);
setState(() {
data = resBody;
});
print(resBody);
return "Sucess";
}
#override
void initState() {
super.initState();
this.getSWData();
}
#override
Widget build(BuildContext context) {
return new Scaffold(
appBar: AppBar(
title: Text("Hospital Management"),
),
body: new Center(
child: new DropdownButton(
items: data.map((item) {
return new DropdownMenuItem(
child: Row(
children: <Widget>[
Text(item['item_name']),
],
),
value: item['id'].toString(),
);
}).toList(),
onChanged: (newVal) {
setState(() {
_mySelection = newVal;
});
},
value: _mySelection,
),
),
);
}
}
modify this,
children: <Widget>[
Text(item['item_name']),
Text(item['item_name']),
Text(item['item_name']),
],
