Introduction
Ok, now let’s start with what these frameworks are. Flutter is a UI toolkit from Google, launched in 2017. React Native, built by Meta in 2015, is based on JavaScript and React.
Both help developers write a single codebase for Android and iOS. That’s why they’ve gained serious popularity in recent years.
Overview of Flutter
Flutter uses Dart, a language designed by Google. It compiles into native code and skips the need for a bridge.
The UI is built from widgets. These are drawn using its rendering engine called Impeller. That gives Flutter apps a consistent look regardless of platform.
Hot reload works instantly and the widget system makes UI customization fast and flexible. Flutter powers apps like Google Pay and eBay Motors.
Overview of React Native
Now let’s switch gears to React Native. It’s based on JavaScript and lets developers reuse their React skills for mobile development.
React Native uses native components under the hood. Buttons and menus feel right at home on Android and iOS.
The newer JSI architecture boosts performance. The Hermes engine improves speed, especially on Android. Apps like Instagram and Shopify use React Native to serve millions.
Key Difference
Where They Overlap
By the way, both frameworks offer a lot of the same benefits:
- One codebase for Android and iOS
- Hot reload to test UI changes instantly
- Strong communities and documentation
- Free to use without licensing costs
They both aim for near-native performance too.
Use Flutter If…
So, one question arises: when does Flutter stand out?
- You want full control over UI design
- You plan to target web, desktop and mobile
- You need performance for animations or custom visuals
Flutter is also a good choice if you’re building everything from scratch.
Use React Native If…
Now, React Native makes more sense if:
- Your team already knows JavaScript
- You’re integrating into an existing native app
- You prefer platform native UI
React Native is great when speed of development matters.
Developer Experience
Flutter feels more all in one. You use Dart, the Flutter SDK and DevTools together. That helps when managing builds and debugging.
React Native builds on web development tools. You’ll likely use VS Code and Chrome DevTools. Tools like Expo make setup easier.
Both frameworks support hot reload. Flutters reload is highly reliable and speeds up UI testing.
Performance in Practice
Flutter compiles directly to native code. That means less overhead and better animation performance.
React Native used to rely on a JavaScript bridge. Now with JSI and Hermes, performance has improved a lot.
For most apps, both perform smoothly. For complex animations, Flutter might edge ahead. For app size and fast startup, RN may have an advantage.
Ecosystem and Tools
React Native leverages NPM. You’ll find libraries for navigation, animations and data handling. It’s very flexible, but quality can vary.
Flutter uses pub.dev. Many plugins are built or endorsed by Google. That leads to a more curated experience.
Both communities are active. Flutter is growing fast. RN has deep support for native integrations.
Development Speed and Productivity
Time-to-market is a critical consideration for app developers.
Flutter claims faster development times, mainly attributable to its Hot Reload feature. This feature enables developers to make instantaneous changes to the codebase and visualize the impact instantly.
React Native offers its Live Reload functionality, allowing for quick iterations and immediate feedback.
Hot Reload and Live Reload features, both frameworks offer various tools and features that enhance developer productivity and contribute to faster app development.
Which One Fits Your Team?
Ask these questions:
- Do you already use React or JavaScript? Use React Native.
- Want complete UI control? Go Flutter.
- Targeting mobile and desktop? Flutter has better built-in support.
Try a proof of concept in both if you are unsure. Each has different strengths.
Choosing the Right Framework for Your Mobile App Development Project
Identifying the specific requirements and goals of the project is crucial when making the framework choice. Customer should consider factors such as app complexity, target platforms, and the development team’s skill set and availability. Evaluating these aspects will help in selecting the framework that aligns with the project’s objectives and long-term vision.
Real World Projects
By the way, if you are wondering whether these frameworks are really used in high stakes, real products, the answer is absolutely yes. Let’s look at some examples of popular apps built with Flutter and React Native:
Apps built with Flutter:
- Google Pay: Yes, the app that handles financial transactions for millions is built with Flutter (Google uses Flutter internally for several apps). The smooth animations and consistent design of Google Pay across Android and iOS showcase Flutter’s strengths.
- Alibaba (Xianyu): Alibaba’s massive ecommerce platform in China used Flutter to build parts of their app. They reported faster development and a beautiful uniform UI crucial for their brand.
- BMW & Mercedes-Benz Apps: Leading automotive companies have embraced Flutter for some of their customer-facing apps. The BMW app for instance uses Flutter to deliver a snappy experience for car owners, and Toyota has even used Flutter for in-vehicle infotainment systems.
- eBay Motors: The eBay Motors app for browsing and buying vehicles is built with Flutter, leveraging rich animations and an intuitive interface that feels identical on iPhones and Android devices.
- Hamilton Musical App: An interesting early example the official app for the Broadway hit Hamilton was built in Flutter, engaging fans with a single codebase experience.
Flutter’s ability to craft custom UIs has attracted fintech apps, shopping apps, and even some game-like apps. It’s proven in production with large user bases.
Apps built with React Native:
- Facebook and Instagram: It’s no surprise React Native was created by Facebook, and they’ve used it in many parts of their flagship apps. Instagram in particular famously integrated React Native to ship features faster to both iOS and Android users.
- Facebook Messenger: Facebook messaging app has used React Native for certain features (the team has even open-sourced many RN components that came out of Messenger).
- Shopify: The ecommerce platform Shopify has fully bought into React Native. Their customer facing Shop app and many merchant apps are built with RN, benefiting from the ease of using one codebase.
- Microsoft Office and Teams (Mobile): Microsoft has shown love for React Native. The mobile versions of Office (Word, Excel, PowerPoint) have parts rebuilt in React Native, and the Microsoft Teams mobile app also leveraged RN in some sections. Microsoft even maintains RN for Windows and RN for macOS to extend its use.
- Tesla: The Tesla mobile app (for controlling Tesla vehicles) is widely believed to be built with React Native. It provides a native like performance for features like unlocking the car, flashing lights, etc., across both platforms with one codebase a big win for Tesla’s small software team early on.
- Pinterest: Pinterest’s app team has used React Native to accelerate their feature development, taking advantage of the cross-platform nature to roll out updates simultaneously.
- Uber Eats: Uber’s food delivery app has portions built in React Native (especially the restaurant dashboard side of the app). They chose RN to iterate quickly on UI across platforms while keeping performance high.
Conclusion
Both Flutter and React Native are powerful cross-platform frameworks, each offering unique advantages and capabilities.
Flutters rich UI capabilities and fast development cycle make it a compelling choice for visually appealing applications. On the other hand, React Native’s extensive community support and industry adoption make it a reliable and mature framework.
The choice between Flutter and React Native should be based on a thorough evaluation of the project’s requirements, team expertise, and long term scalability. By utilizing the strengths of each framework, developers can create exceptional and user friendly applications that leave a lasting impression on users.
