Introduction
If you want to learn how to create your first Flutter app. Flutter is Google’s open-source UI toolkit for building applications from a shared codebase, with support for Android, iOS, web, Windows, macOS, Linux, and embedded experiences.
Flutter applications are written primarily in Dart, and the framework uses a widget-based approach for building interfaces. Its development workflow includes features such as hot reload, while modern Flutter releases also use the Impeller rendering engine on supported platforms.
In this beginner-friendly Flutter app tutorial, you’ll learn how to install Flutter, create a project, understand the basic application structure, build a simple interface, run it on a device or emulator, and prepare for the next stage of Flutter development.
What Is Flutter?
Flutter is a cross-platform development framework built around the Dart programming language.
Instead of maintaining completely separate UI code for every supported platform, developers can build much of an application’s interface and business logic from one Flutter codebase.
Flutter currently supports mobile, desktop, and web deployment. Its supported platforms include Android and iOS on mobile, Windows, macOS, and Linux on desktop, and modern browsers on the web.
Flutter’s architecture is heavily based on widgets. Buttons, text, layouts, navigation elements, padding, lists, and many other interface components are represented through widgets.
This makes Flutter particularly useful when you want detailed control over a consistent, custom application interface.
Why Learn Flutter?
Some of the reasons developers continue to choose Flutter include:
- One codebase for multiple platforms
- Dart’s modern language features
- Stateful hot reload during development
- Large Flutter and Dart package ecosystem
- Customizable widget-based UI
- Mobile, desktop, and web support
- Native platform integration when required
- Modern rendering through Impeller
- Support for WebAssembly on the web
- Growing AI development tooling
Flutter’s official documentation also highlights its ability to integrate platform-specific functionality through plugins or native code when a Flutter package isn’t sufficient.
Flutter vs. React Native
Flutter and React Native are both popular approaches to cross-platform application development, but they use different technologies.
| Feature | Flutter | React Native |
| Primary language | Dart | JavaScript/TypeScript |
| UI approach | Flutter widgets | React components |
| Cross-platform development | Yes | Yes |
| Android | Yes | Yes |
| iOS | Yes | Yes |
| Web | Yes | Available through ecosystem |
| Desktop | Windows, macOS, Linux | Platform-dependent ecosystem |
| Hot reload | Yes | Yes |
| Custom UI | Extensive | Extensive |
| Official AI tooling | Flutter AI tooling available | Ecosystem-dependent |
There is no universal winner between the two. Your existing programming experience, team expertise, target platforms, ecosystem requirements, and application architecture should influence the decision.
If you’re already comfortable with JavaScript and React, React Native may feel familiar. If you prefer Dart or want Flutter’s widget-based UI architecture and broad official platform support, Flutter may be a natural choice.
How to Create Your First Flutter App
Now let’s look at how to create your first Flutter app using the current development workflow.
Prerequisites for Flutter App Development
Before creating your first project, you’ll need:
- A computer running macOS, Windows, Linux, or ChromeOS
- Flutter SDK
- An editor such as VS Code or Android Studio
- Dart and Flutter tooling
- A physical device or emulator for your target platform
If you’re targeting Android, you’ll need the appropriate Android development tools. If you’re targeting iOS, Flutter’s iOS development workflow requires macOS. Flutter’s current platform setup documentation provides separate instructions for each target.
For beginners, Flutter’s current documentation recommends using the VS Code setup flow as one of the easiest ways to get started. Manual installation is also available when you need a particular SDK version or a more customized environment.
Step 1: Install Flutter
Download and install the Flutter SDK using the official Flutter installation instructions.
After installation, open a terminal and run:
flutter doctor
For more detailed diagnostics, use:
flutter doctor -v
Flutter Doctor checks your development environment and identifies missing components or configuration problems.
Resolve the important issues reported by the command before continuing.
You can then verify the installed Flutter version with:
flutter –version
Keep Flutter updated through the supported installation workflow rather than relying on commands from older tutorials.
Step 2: Set Up Your IDE
You can develop Flutter applications using editors such as:
- Visual Studio Code
- Android Studio
- IntelliJ-based IDEs
- Other supported Code OSS-based editors
Install the Dart and Flutter extensions or plugins for your chosen environment.
VS Code is a convenient option for beginners because Flutter’s current documentation provides a dedicated workflow for creating projects directly from the editor.
Step 3: Create a New Flutter Project
The Flutter command-line interface provides a straightforward way to create a new application.
Open your terminal and run:
flutter create my_first_app
Then move into the project:
cd my_first_app
Run the application with:
flutter run
Flutter will identify available devices and allow you to select where the application should run.
The current Flutter documentation also supports creating projects directly through VS Code, Android Studio, IntelliJ, Antigravity, or the terminal.
For a minimal project, you can also use:
flutter create –empty my_first_app
This creates a project with a minimal starting application rather than the more complete default template.
Step 4: Understand the Flutter Project Structure
After creating your project, you’ll see several files and directories.
The most important one for a beginner is:
lib/main.dart
The main.dart file contains the entry point of your Dart application.
A minimal Flutter application can look like this:
import ‘package:flutter/material.dart’;
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return const MaterialApp(
home: Scaffold(
body: Center(
child: Text(‘Hello, Flutter!’),
),
),
);
}
}
The main() function starts the application, while runApp() places the root widget into the Flutter application.
The official Flutter tutorial uses the same fundamental structure for a basic application.
Step 5: Build Your First Flutter App Example
Let’s turn the basic application into a simple welcome screen.
Replace the contents of lib/main.dart with:
import ‘package:flutter/material.dart’;
void main() {
runApp(const MyFirstApp());
}
class MyFirstApp extends StatelessWidget {
const MyFirstApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: ‘My First Flutter App’,
home: Scaffold(
appBar: AppBar(
title: const Text(‘My First Flutter App’),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Text(
‘Welcome to Flutter!’,
style: TextStyle(
fontSize: 28,
fontWeight: FontWeight.bold,
),
),
const SizedBox(height: 16),
const Text(
‘My first Flutter app is running.’,
),
const SizedBox(height: 24),
ElevatedButton(
onPressed: () {
debugPrint(‘Button pressed’);
},
child: const Text(‘Get Started’),
),
],
),
),
),
);
}
}
This example introduces several fundamental Flutter concepts:
- MaterialApp creates the application shell.
- Scaffold provides a standard page structure.
- AppBar creates the top application bar.
- Column arranges widgets vertically.
- Center positions content in the middle.
- Text displays text.
- ElevatedButton creates an interactive button.
- SizedBox adds spacing.
These building blocks are worth learning because you’ll use variations of them in many Flutter applications.
Step 6: Use Hot Reload While Developing
One of Flutter’s most useful development features is hot reload.
After changing your Dart code, you can reload the running application without performing a complete application restart in many development scenarios.
This makes experimenting with layouts, widgets, colors, text, and interactions considerably faster.
Flutter also provides hot restart when you need to restart the Dart application state.
Step 7: Run and Test Your Flutter App
You can run your application on:
- Android devices
- iPhones and iPads
- Web browsers
- Windows
- macOS
- Linux
The exact development requirements vary by target platform. For example, iOS development requires macOS, while Windows desktop development requires Windows.
For Android development, you can use a physical Android device or an emulator.
For early development, testing on a real device is also valuable because it exposes issues that may not appear in an emulator.
Flutter Performance
Performance is an important consideration when building a production Flutter application.
Flutter’s modern rendering architecture includes Impeller, which is the default rendering engine for iOS and Android API 29+ as of Flutter 3.27. Flutter 3.47 also enables Impeller by default on macOS and Linux, with Windows support available as well.
Flutter also provides DevTools for profiling and diagnosing performance problems.
Avoid judging performance solely from debug builds. Flutter’s documentation recommends profiling performance using profile mode when investigating rendering problems.
For example, avoid unnecessarily rebuilding large portions of the widget tree and use efficient scrolling widgets such as ListView for large lists.
Flutter Web and WebAssembly
Flutter is no longer limited to mobile applications.
Flutter supports web deployment, and Dart and Flutter can compile applications to WebAssembly as well as JavaScript.
This means a Flutter project can potentially target mobile and browser experiences from a shared codebase.
However, don’t automatically assume that one UI should be identical everywhere. Build responsive and adaptive layouts that account for differences between phones, tablets, desktop screens, and browsers.
AI-Assisted Flutter Development
AI is becoming part of the modern Flutter development workflow.
Flutter’s official documentation now includes dedicated AI resources covering AI coding assistants, agent skills, the Dart and Flutter MCP server, and Flutter’s AI Toolkit.
AI can help developers:
- Generate boilerplate
- Explain Flutter widgets
- Debug errors
- Refactor code
- Create tests
- Explore UI ideas
- Build AI-powered application features
Flutter also provides an AI Toolkit with components for conversational interfaces, streaming responses, voice input, multimedia attachments, and function calling.
However, review AI-generated code carefully. Verify APIs against current Flutter documentation, run static analysis and tests, and avoid blindly accepting generated architecture or package recommendations.
Common Flutter Beginner Mistakes
When learning how to create your first Flutter app, avoid these common mistakes:
- Following outdated installation tutorials
Flutter’s setup process evolves, so use the current installation documentation. - Learning widgets without understanding Dart
Basic Dart knowledge makes Flutter much easier to understand. - Putting everything in main.dart
Small tutorials can use one file, but production applications should be organized into logical components. - Ignoring responsive design
A layout that works on a phone may not work well on a desktop screen. - Testing only in debug mode
Profile and release builds provide a more realistic picture of application performance. - Copying AI-generated code without verification
AI tools can accelerate development, but developers remain responsible for correctness, security, dependencies, and maintainability.
