# Flutter Classes
```dart
import 'package:flutter/cupertino.dart';
void main() {
runApp(app);
}
```
## Types of widgets
> Stateless ---> stless
> Stateful ---> stful
```dart
import 'package:flutter/material.dart';
import 'package:flutter_class/contact_page.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: "Flutter Class",
debugShowCheckedModeBanner: false,
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple)),
home: ContactPage(),
);
}
}
```
```dart
import 'package:flutter/material.dart';
class ContactPage extends StatefulWidget {
const ContactPage({super.key});
@override
State createState() => _ContactPageState();
}
class _ContactPageState extends State {
@override
Widget build(BuildContext context) {
return const Scaffold();
}
}
```
```dart
import 'package:flutter/material.dart';
class ContactPage extends StatefulWidget {
const ContactPage({Key? key}) : super(key: key);
@override
State createState() => _ContactPageState();
}cons
class _ContactPageState extends State {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Contact Page 👋")),
body: SingleChildScrollView(
child: Column(
children: [
for (var student in students) studentsList(student),

),
),
);
}
Widget studentsList(String name) {
