React Native & Flutter – What Are They and How Do They Work?
Before you dive into coding, it’s important to know how these frameworks actually work. React Native and Flutter both allow you to build cross-platform mobile apps, but they take different approaches to achieve this. So, how do they stack up? Let’s take a look.
React Native
Developed by: Meta (formerly Facebook)
Language Used: JavaScript
Why Developers Like React Native
- Since React Native is built on JavaScript, one of the most widely used programming languages, developers with web experience can quickly adapt to mobile development.
- With a vast library of third-party plugins, pre-built components, and integrations, developers can speed up development by using existing tools instead of coding everything from scratch.
- Features like hot reloading allow developers to see changes instantly while coding, reducing time spent refreshing or recompiling the app.
- Companies that already have web applications can reuse significant portions of their code, saving both time and money.
- React Native bridges the gap between JavaScript and native mobile capabilities, allowing apps to use essential features like GPS, camera, Bluetooth, and push notifications without needing a completely native approach.
React Native acts as a bridge between JavaScript and native components, letting developers write one codebase that runs on both iOS and Android. Apps like Instagram and Airbnb use React Native to ensure fast development cycles while maintaining a native-like experience.
It doesn’t compile directly into native code but instead communicates with native elements through a JavaScript bridge. This makes it flexible but may cause slight performance lags in highly complex applications.
Flutter
Developed by: Google
Language Used: Dart
Why Developers Like Flutter
- Instead of using platform-specific UI elements like React Native, Flutter draws its own UI components from scratch. This ensures the app looks identical across iOS and Android, reducing inconsistencies.
- Flutter provides a large selection of built-in UI widgets, making it easier to create high-quality user interfaces without relying on third-party libraries.
- Unlike React Native, which relies on a JavaScript bridge, Flutter compiles directly into native code. This makes it much faster and more efficient, especially for animations and heavy processing tasks.
- Many essential features like state management, navigation, and testing are built into Flutter, reducing the need for third-party dependencies and minimizing compatibility issues.
- Flutter’s Skia graphics engine is optimized for rendering smooth animations, transitions, and detailed UI elements, making it a top choice for visually immersive applications.
Flutter takes a different approach by rendering everything from scratch using its Skia engine. Apps like Google Pay and BMW’s mobile app use Flutter to deliver smooth animations and a visually rich user experience across multiple devices.
Instead of relying on native components, it draws UI elements directly onto the screen, ensuring a highly consistent experience across devices. This results in smoother animations and better performance for apps that require intensive graphics or real-time interactions.
