Ever wondered how to build Android and iOS apps without writing code twice? The answer is simple: Flutter!
Flutter is a cool toolkit from Google that lets you build one codebase for two (or even more) platforms. In this article, we’ll explore what Flutter is, how it works, and why it’s become so popular. Let’s get into it!
What is Flutter?
Flutter is an open-source UI framework created by Google for building mobile, web, and desktop apps from a single codebase.
With Flutter, you only need to write code once to deploy your app to both Android and iOS. It also supports Web and Desktop platforms now. Awesome, right?
Why Did Google Create Flutter?
Before Flutter, mobile developers struggled with:
- Writing separate code for Android and iOS
- UI inconsistencies
- Duplicated effort for new features
- Testing complexities
Flutter solves this by providing:
- Faster development
- Unified and consistent UI
- Single logic base for all platforms
- Rapid prototyping capabilities
How Flutter Works
Flutter doesn’t use native UI components. Instead, it draws everything from scratch using its own rendering engine called Skia.
This allows Flutter to deliver consistent UIs and smooth animations across all platforms.
What Language Does Flutter Use?
Flutter uses Dart, a programming language also developed by Google. If you're familiar with JavaScript, Java, or C#, Dart will feel natural to you.
Dart is:
- Easy to learn
- Modern and efficient
- Great for asynchronous programming
What Can You Build with Flutter?
You can build:
- Mobile apps (Android & iOS)
- Web apps
- Desktop apps (Windows, macOS, Linux)
- Embedded apps (like IoT)
Top Features of Flutter
1. Hot Reload
Make code changes and see them instantly without restarting your app. It speeds up development dramatically.
2. Rich Widget Library
Everything in Flutter is a widget. Combine them to build any UI:
- StatelessWidget – for static UIs
- StatefulWidget – for dynamic UIs
3. Material & Cupertino Design
Use Material widgets for Android-style design and Cupertino widgets for iOS-style design—built right into Flutter.
4. Near-Native Performance
Flutter apps compile to native ARM code, making them fast and smooth.
Flutter Plugin Ecosystem
Flutter has thousands of ready-to-use plugins for:
- Firebase integration
- Camera, GPS, and Maps
- Local storage
- Payment gateways
Need something custom? Use platform channels to call native Android/iOS code.
Real Apps Built with Flutter
- Google Ads
- Alibaba
- BMW
- eBay Motors
- Nubank
