4. Choose Kotlin as the programming language.
5. Click on "Finish".

Once you have created your new Flutter application using Kotlin, you can start writing your application code.

2. Build a simple Flutter application using Kotlin:

Here is an example of how to build a simple Flutter application using Kotlin:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'My Flutter App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('My Flutter App'),
        ),
        body: Center(
          child: Text('Hello, world!'),
