Flutter Vs React Native: Which Is Better For Your Business

Ideas Are Easy. Implementation Is Hard.

Are you looking for quick & cost-effective app development for your startup? but you’re not sure which technology to choose?

Native apps are more costly but they are still the best choice when it comes to user experience and performance. But nowadays Cross-platform apps are easy and quick to build, but it’ll take more effort to deliver an equivalent user experience on the respective platform.

Cross-platform apps are becoming more and more popular, which has increased the need for creating platforms to create them. There have been several solutions developed, but Flutter and React Native appear to be the most popular ones. Using the same codebase, both are created to function on iOS, Android, and maybe other platforms. It can be harder to choose between Flutter vs React Native.

Why Is Hybrid App Useful For Startup Business Owners?

The latest research from Statista places Flutter as the leading cross-platform mobile development framework in 2021. Flutter surpasses React Native by 4% (42% for Flutter against 38% for React Native). Still, it's fair to say the two technologies are almost equally popular.

  • Developing Hybrid apps (using Flutter or React Native) saves time, cost-effective and the results are almost as satisfying as with a native app.
  • Hybrid app development reduces development time and saves money for startups.
  • When something goes wrong Offline libraries have all answers, the developer just needs to know where to find them, and how to get help if there is a problem.
  • It is simpler to manage hybrid apps. With all the systems updates, it could be challenging to keep track of how different codes are affected. This is no longer an issue with hybrid apps as you just need one code for all of them.
  • They are suitable for Android and iOS. It is not worth spending extra time and money on building another app.
  • They allow simple third-party app integration.
But what is the solution? Cross-platform mobile application solutions like Facebook’s React Native and Google’s Flutter. But which is better: Flutter or React Native? Let’s explore it.

Differentiate Flutter Vs React Native

What Is Flutter? - Overview

Flutter is an open-source, cross-platform mobile development framework that uses the Dart programming language. Google created Dart and Flutter and uses the framework for some of its biggest applications. Its initial alpha release was back in May 2017 but it's much younger than React Native.

What Is React Native - Overview

React Native was first developed as a Facebook internal sprint project in 2013 and released available to people in 2015.

Facebook's React Native is perhaps the world champion of cross-platform mobile development. A JavaScript framework built upon the React library, React Native helps you ship IOS and Android apps with a single code base.

Performance Comparison: Flutter Vs React Native

The fact that Flutter is natively built to either ARM or x86 makes it faster than the competition when it comes to performance. Because React Native still uses the JavaScript layer and isn't compiled to native code, it performs slower than Flutter.

Architecture: Flutter Vs React Native

It uses the Dart framework which has most of the components inbuilt so it's bigger and often does not require the bridge to communicate with the native modules. The architecture of the Flutter engine is explained in detail in Github Wiki

React Native uses the architecture from Facebook. React Native code is compiled into native code at runtime. The architecture heavily relies on the JS runtime environment architecture, also known as JavaScript bridge. There is a detailed article on the core architecture of React Native here.

User Experience: Flutter Vs React Native

Flutter offers a rich user experience with simplified tools, elements, and even customized widgets. The generational garbage collection feature is also a part of Dart which helps in creating UI frames for objects that may be temporary.

It's difficult for React Native to keep up with the continual change in requirements for native platforms as iOS' Style Design and Android's Material Design evolve daily. Making consistent designs for different platforms is further complicated by ready-made React Native UI kits like React Virgin, Shoutem, and Ant Design. However, several essential elements, such as the ScrollView fixed header, Modal elements, Activity indicators, Snap carousels, and Pagination elements, significantly enhance the UX on many platforms.

Ease Of Testing: Flutter Vs React Native

Flutter is a cross-platform development tool for Android and iOS apps. It offers extensive support for testing apps at the unit, widget, and integration levels. Flutter also boasts of detailed documentation to build and release apps on the Play Store and App Store.

React Native has no official support for UI level testing and Integration testing. It is still relying on third-party libraries for build and release automation. The entire framework doesn't offer any automated steps to deploy the iOS apps to App Store. RN suggests developers define the manual process of deploying the app through Xcode.

Community Around: Flutter Vs React Native

Modularity: Flutter Vs React Native

With its pub package structure, Flutter provides improved accessibility for a diverse team as well as the partitioning of project codes into several modules. With the flexibility to connect to other modules, your team can quickly add or modify a codebase. The BMW architects described how they made it possible for several teams with various skill sets to collaborate with Flutter with ease at the Droidcon NYC conference in 2019.

React Native could provide less support for modularity when compared to Flutter. It could be challenging for Reactjs, iOS, and Android developers to communicate with one another. The code fragmentation in React Native may cause problems for various teams without knowledge. React Native, on the other hand, provides the opportunity for developers from other teams to partially collaborate by combining straightforward native components from several OS platforms.

Learning Curve: Flutter Vs React Native

Flutter is not difficult to learn. While writing code in Dart may seem weird, this is what makes creating Flutter applications simpler. All a beginner needs to master this framework is a foundational understanding of native Android or iOS coding. Additionally, developers claim that Flutter documentation runs far more smoothly than React Native documentation.

For those who have developed applications using JavaScript, learning React Native is surprisingly easy. However, web development is distinct from the creation of mobile apps, which is why it can be challenging for mobile developers to understand and use the framework. The learning curve has been lowered by the numerous libraries, in-depth docs, and tutorials that React Native has released over time.

Code Maintainability: Flutter Vs React Native

In Flutter, The time taken for releasing quality updates and making immediate changes in the application is considered to be better than the hot reloading capacity of React Native. The simplicity of code helps developers spot issues, source external tools, and support third-party libraries. Furthermore, the stateful Hot Reloading feature immediately resolves issues.

In React Native, upgrading and debugging the code is a pain. When you fork the code to suit your application, it interferes with the framework's logic. Most of the native components might have a third-party library dependency. Often these libraries are outdated and cannot be maintained properly.
