Create a First Flutter Application

Flutter is an open-source UI software development kit created by Google. It allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase. Flutter uses the Dart programming language, which is also developed by Google, and provides a rich set of pre-built widgets that make it easy to create beautiful user interfaces.

In the below PDF we discuss about Create a First Flutter Application  in detail in simple language, Hope this will help in better understanding.

Setting Up Flutter:

Before we dive into creating our first Flutter application, let’s make sure we have Flutter installed on our system. You can follow the official installation guide provided by Flutter to get set up on your preferred operating system: Flutter Installation Guide.

Once Flutter is installed, you can verify the installation by running the following command in your terminal:

flutter doctor

This command will check your system for any missing dependencies and provide instructions on how to install them if necessary.

Creating a New Flutter Project:

Now that we have Flutter installed, let’s create a new Flutter project. Open your terminal or command prompt and run the following command:

flutter create my_first_flutter_app

Replace my_first_flutter_app with the desired name for your project. This command will generate a new Flutter project with the default directory structure and files.

Exploring the Project Structure:

Once the project has been created, navigate to the project directory and take a look at the files and folders that Flutter has generated for us. The most important files and directories are:

  • lib/: This directory contains the Dart code for your application. The main.dart file is the entry point for your application.
  • android/ and ios/: These directories contain the native Android and iOS code for your application, respectively.
  • pubspec.yaml: This file specifies the dependencies for your Flutter project. You can add any third-party packages or plugins that your application requires here.

Writing Your First Flutter App:

Now let’s open the main.dart file in the lib/ directory and start writing some code. By default, Flutter generates a simple “Hello, World!” application. We can modify this code to create our own custom application.

import 'package:flutter/material.dart';

void main() {

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

In this code, we’ve created a simple Flutter application with a MyApp widget that extends StatelessWidget. The build method of MyApp returns a MaterialApp widget, which is the root of our application. Within MaterialApp, we’ve defined a Scaffold widget with an AppBar and a body containing a Center widget with a Text widget displaying “Hello, Flutter!”.

Running the Application:

Now that we’ve written our Flutter application, let’s run it on a device or emulator. Make sure you have a device connected or an emulator running, then execute the following command in your terminal:

flutter run

Flutter will compile your code and launch the application on the connected device or emulator. You should see the title “My First Flutter App” in the app bar and the text “Hello, Flutter!” displayed in the center of the screen.


Congratulations! You’ve successfully created your first Flutter application. In this tutorial, we covered the basics of setting up Flutter, creating a new project, exploring the project structure, writing Dart code for our application, and running the application on a device or emulator. This is just the beginning of your journey with Flutter, and there’s so much more to explore and learn.

Flutter is an open-source UI software development kit created by Google. It is used to build natively compiled applications for mobile, web, and desktop from a single codebase.

Flutter primarily uses the Dart programming language, which was also developed by Google. Dart is an object-oriented language with syntax familiar to many developers.

Flutter supports building applications for various platforms, including iOS, Android, web, and desktop (Windows, macOS, Linux).

Some key features of Flutter include hot reload for rapid development, a rich set of customizable widgets, a reactive framework, and native performance.

Hot reload is a feature in Flutter that allows developers to instantly see the changes they make to their code reflected in the running app without losing the app state.
