How to Create a Mobile App with Flutter: A Beginner’s Tutorial
Flutter is Google’s open-source framework for building native iOS and Android apps from a single Dart codebase. With hot reload and a rich widget library, you can go from idea to working prototype in hours rather than weeks.
Before you start, install the Flutter SDK, Android Studio (or Xcode on macOS), and VS Code with the Flutter extension. Run flutter doctor to confirm everything is configured correctly.
1. Create a New Project
Open your terminal and run flutter create my_app, then cd my_app and flutter run. The default counter app launches on your emulator or connected device.
2. Understand Widgets
Everything in Flutter is a widget. Layout comes from nesting them: Scaffold for page structure, Column and Row for arrangement, and Container for styling.
3. Build Your First Screen
Replace the counter code with your own. A minimal screen follows these rules:
- Wrap content in MaterialApp and Scaffold
- Use Text, Icon, and ElevatedButton for basics
- Store changing data in a StatefulWidget with setState
4. Add Packages and Test
Extend functionality with pub.dev packages like http or provider. Test on both platforms, then run flutter build apk or flutter build ios to ship.
Conclusion
Flutter lets one codebase target every screen size. Start small, master widgets, and iterate with hot reload — your first app is closer than you think.
