Two technologies that help create mobile apps are earning a lot of traction- for all the good reasons- React Native and Flutter. If you look at the for and check what’s trending, React Native wins here but Flutter is catching up! Google Trends Flutter Vs. React Native These two technologies have a lot of things in common. Both allow developers to create native apps with a single codebase. This means: You create truly native applications that users can download and install from the AppStore or the Play Store. You create apps using one codebase with cross-platform mobile app development. But, React Native and Flutter differ in a lot of the details, which can easily confuse you as to which of both is an ideal choice. Here’s a comprehensive Infographic and a FAQ section to help you decide. What is the basic difference between Flutter and React Native? React Native is three years older than Flutter, introduced in 2015. While React Native is backed by Facebook, Google supports Flutter. React Native’s presentation language is proprietary but oddly resembles JSX. Flutter uses Dart as its presentation and procedural language. React Native’s procedural language is JavaScript. Both frameworks are free and steadily growing in popularity. Why is Flutter gaining so much popularity in 2019? The Flutter framework boasts of UI rendering components, navigation, testing, device API access, stateful management, and several libraries. The component set eliminates any need for using third-party libraries. Flutter’s widgets for Material Design and Cupertino are helpful in rendering UI easily on both Android and iOS. For its high developer productivity, easy and painless set up on CI/CD services with CLI tools, and reliable support from Google, Flutter has become instant popularity in 2019. Who has better performance? Consider the performance factor, and you see Flutter easily winning. The standard for Flutter is 60 frames per second, a rather high standard for React Native. React Native uses JavaScript Bridge to initialize screens and so doesn’t work as seamlessly. Dart Analysis and Flutter Inspector help developers meet the performance standard of 60fps. Flutter works through Android Studio, using its tools for debugging and optimizing code. Do React Native apps lead to battery drain? Assume you are building a taxi booking mobile application. Such an application will make extensive use of the location tracking feature. When the app is not in use, the feature will still do its job in the background. This will make the mobile app resource and power-extensive. When built with React Native, such a mobile app can drain a lot of battery power and impact CPU cycles. As a matter of fact, React Native is better suited for simplistic apps with fewer features and a simple interface. Is Code Push a significant reason to choose React Native over Flutter? It’s exciting to be able to push bug fixes in real-time for your users. The ‘hot update’ or ‘code push’ feature of React Native allows developers to apply patches without having to go through the app store release process again. Futter does not support this feature at all. While it looks like added flexibility in code development, it helps to know that Apple rejected some apps with the ‘hot code push’ feature. The issue with such apps is that they update native code on the fly. Apple rejected the apps as there could be a vast difference in these apps after code push, impacting whether or not Apple wants to approve them. A substantial restriction on using code push is that you are not supposed to make major changes to the app’s functionality OTA (over the air). Who has better support and community guidance? React Native came about earlier than Flutter. Naturally, this has its effects. One of React Native’s standout and immediate benefit is community support, which is still scanty with Flutter. React Native’s community accelerates the growth of the framework and makes it the better option for creating quick MVPs. Better community support also directly impacts the available features, libraries, and tools for development. Currently on GitHub, React Native has 78,400 stars, while Flutter has 68,000. Despite that, the number of components in Flutter is growing faster, showing Flutter’s community is more active. While Flutter has 5,600 issues and 109 pull requests, React Native only has 400 issues and 78 pull requests. Who has the shorter learning curve - React Native or Flutter? For someone familiar with JavaScript, learning to code in React Native will be like a walk in the park. Dart is a natural fit for developers who know Java and C#. In and of itself, Dart is an easy-to-learn language. Developers familiar with other OOP languages such as Swift and Kotlin will also find Flutter easier. Besides, if you have no background in either, Dart will be much easier for you to get into than JavaScript, as the former does not have the unique characteristics that catch developers off guard in JavaScript. Is Hot Reloading a significant reason to choose Flutter over React Native? Flutter’s hot reloading has got the developers drooling. With this feature, Flutter offers more dynamic and faster mobile app development. Developers can make changes to the code OTA and the application would immediately reflect them. The hot reloading typically takes milliseconds to reflect the made changes. This feature can be a savior when you want to fix bugs, add features, or try out innovative ideas instantly. Hot Reload is also a nice-to-have for developer-designer collaboration. Therefore, Hot Reloading might well be the feature that makes up your mind about picking Flutter over React Native. Should I learn - React Native or Flutter? JavaScript is the most popular programming language out of the two. But, for someone unfamiliar with either, Dart can be a breeze to learn and code into. If you have any experience with object-oriented programming, learning Dart will be child’s play. Coming to the potential in the two frameworks, we clearly see Flutter becoming the next popular framework for cross-platform app development. Therefore, this might be the right time for anyone to equip themselves with the skills in Dart to take the plunge into a refreshed career when Flutter becomes the rage. The career prospects - Flutter vs. React Native React Native is a popular cross-platform development framework today. But, looking at the future potential of Flutter, it might be more suitable for you to think about a career in Flutter app development. For developers considering a career in either React Native or Flutter, we incline toward Flutter. Since the technology is still increasing in popularity, this is a rising tide. An opportunity for developers to embark on a career in Flutter development now so that they can upskill and be in demand when Flutter becomes the talk of the town. Will Flutter kill React Native? While React Native currently has great community support, excellent code structure, and steady growth, Flutter has the potential to become the future of mobile app development. As time rolls by, we will see Flutter swiftly leaving behind React Native to become the better tech framework for cross-platform mobile app development. When to NOT use Flutter? Flutter might not be the best fit when: Your app needs support for 3D Touch. The feature is not on Flutter yet but is part of the team’s long-term plan. (3D Touch was replaced by Haptic Touch in the new iPhone XR.) The app design is platform-specific. Your mobile app needs multiple interactions with an operating system. Or, when it needs rare native libraries. You need a minimalist user interface but significantly use the underlying hardware. You want to create a simplistic app on a fast track. When to NOT use React Native? Steer clear of React Native when: Your app needs to handle rare, ultra-specific tasks, such as calculations in the background. You need to enable custom communication via Bluetooth (can be difficult to implement with React Native) You wish to build an Android-only or iOS-only app. If you want to create an app that works on both iOS and Android, React Native can be the ideal choice. But, if you need an app that works on either Android or iOS only, go for a native application for its better performance and functionality.
