In place of model you can use API as you flutter dropdown list source.

import 'datamodel.dart';
class TestSelect extends StatefulWidget {
const TestSelect({Key? key}) : super(key: key);
@override
State<TestSelect> createState() => _TestSelectState();
}
class _TestSelectState extends State<TestSelect> {
var my_services;
_onclicked(value) {
print('Clicked...' + value.toString());
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text(
"CodingMSTR.com",
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.normal,
fontSize: 18),
),
),
body: Column(

onChanged: (String? changedValue) {
