If Flutter vs React Native is your burgeoning question for this year 2021, guess what you are not alone. We no longer need statistics to know about the ever-growing popularity of mobile apps across the world. According to the latest report, global consumers are now spending an average of 4.2 hours per day using apps on their smartphones, an increase of 30% from just two years prior.
Regardless of the industry, every business needs a mobile app to offer customized services to their clients. Are you a part of the world’s most lucrative mobile app industry ? Developing native apps for Android and iOS is quite cost-intensive and time-consuming. On the other hand, you can develop natively-rendered mobile apps for iOS and Android using the same codebase at reduced cost and time with cross-platform development.
Cross-platform apps are highly popular for the obvious benefits. However, choosing the right framework is essential for efficient cross-platform development. In this blog, we compare the two market players React Native vs Flutter to help identify the framework that best suits your app development needs.
Before we dive deep into the comparison, let’s first know what is the difference between flutter and react native.

What is Flutter?
Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, desktop, and embedded devices from a single codebase.
Initially developed by Google, Flutter is now managed by ECMA standard.
It is based on a fast, object-oriented programming language called Dart. The open-source client optimized general programming language was developed and introduced by Google in 2011.
Flutter has a layered architecture that comes with a wide array of in-built components. The layered architecture enables easy and quick UI customization giving the user control over every single pixel on the screen. The combination of Dart framework with a Skia C++ engine ensures that no bridge or medium is required to interact with the native modules.
Flutter architecture comprises the following layers-
- Flutter engine
- Dart framework
Top Companies that opted for flutter
Google, Square, Philips,BMW, eBay, Alibaba
What is React Native ?
Created by Facebook React Native is based on the more generalized React. It is built for mobile app development, especially cross-platform app development. The platform enables the development of robust apps for multiple platforms like android and iOS using a single code base. “Learn once, write anywhere”is indeed the main objective of React Native.
React Native is based on Facebook’s Flux architecture. Facebook utilizes Flux for the client-side web application and it focuses on the unidirectional flow of data. The architecture consists of –
- React code
- The bridge
- Native side
Top Companies that opted for React Native
Facebook, Instagram, Airbnb, Skype, Facebook Ads Manager, Tesla, Bloomsberg
Top features that make Flutter suitable for cross-platform app development
Let’s take a look at the features that make Flutter an ideal choice for cross-platform app development.
Codesharing leads to faster development
Flutter, like any other cross-platform technology, enables developers to use the same codebase for developing iOS and Android apps. This not only speeds up the development process but also reduces cost as you do not need two teams to work on the code.
With the hot reload feature, changes made to the code are immediately visible to the developers in the app preview without having to reload the entire app. As the widgets are immutable only the screens you are currently working on undergo the reloading process. This results in easy bug fixing while enabling developers to experiment with multiple UI elements and features.
Business Logic Components (BLoC)
This architecture pattern is called BLoC (Business Logic Components) and it utilizes streams to separate the app’s user interface from the business logic. Unlike other patterns, in BLoC pattern UI is not loaded with delays. This prevents delays in the app’s performance as animations and screen scrolls work smoothly while the data is loaded from the server.
Flutter has its own rendering engine and this ensures that apps are not affected by any OS update. They still offer the same look and feel in terms of the interface even after a system update.
The final performance and responsiveness of the software are not affected by the number of nested objects in the Flutter code. This is because when the layout is processed there are no recursive calls. Further, Dart can be compiled into the native code in order to enhance app performance.
Top features that make React Native suitable for cross-platform app development
Rich components library
In React Native 0.61, the “live reloading” and “hot reloading” features are combined into a single new feature called “Fast Refresh”. It fixes all the issues of the Hot Reloading feature and provides a great developer experience that speeds up both bug fixing and the development of new features.
React Native employs declarative programming. Unlike native development, it eliminates the need to create a sequence of actions in the app. As a result, it is much easier to spot bugs on the path a user takes.
Strong community support
One of the biggest advantages of using React Native is the huge community support. A developer facing any issues can easily fall back on the community for support.
Flutter vs React Native-
Without further ado, let’s get started with React Native vs Flutter comparison. We will be comparing the two technologies based on the following criteria
Flutter vs. React Native-Performance
Winner -Clearly, Flutter offers better performance than React Native
Flutter vs. React Native-Testing Support
As Flutter is based on Dart, it comes with comprehensive automation test support.Flutter developers and testers have access to a wide spectrum of testing features for unit, integrated, and widget testing of the applications. Further, it also provides detailed documentation about automated app releases. In stark contrast, React Native only offers a limited set of tools for unit testing and zero testing support for UI level and integrated testing.
Winner– With React Native developers depending on tools like Appium and Detox for UI level testing and no automated app deployment support, Flutter is the winner.
Flutter vs. React Native-UI Building
Flutter vs. React Native-Ease of Installation
When it comes to Flutter installation in Windows or macOS, you have to download the installation bundle(Zip file) of Flutter SDK. But then you have to add flutter to the “PATH” variable making things a bit complicated.
Winner-When it comes to ease of installation, Flutter is the clear winner.
Flutter vs.React Native-Documentation
Both Flutter and React Native come with guides to help you get started. But React Native offers little to no information about setup and command-line tools. Whereas, Flutter provides detailed information about setting up the platform. It even has a Flutter doctor to guide developers during the entire process.
Winner– Flutter with more comprehensive documentation is the winner
Flutter vs.React Native-Scalability
Google’s Flutters comes with enhanced flexibility and scalability as the platform is easy to access and integrate. On the other hand, React Native with a virtual DOM & React library, is an incredible framework to build scalable components. Even though it is used in huge apps like Facebook but in certain cases like that of Airbnb it turns out to be too low. This forced the company to switch back to native development as their codebase using React Native became unmaintainable.
Winner- Flutter comes with better scalability capabilities.
Flutter vs.React Native-Community Support
Winner- Undoubtedly, React Native is the winner.
Flutter vs.React Native-Code Maintainability
Upgrading and debugging the code is a pain with React Native. Once you start making changes to the code to cater the application needs, it interferes with the framework’s logic and slows down the development process. Further, almost all the native components come with third-party library dependency. In the long run, it becomes difficult to maintain these libraries as they get outdated.
In contrast, maintaining a Flutter application is much easier. The simple coding enables developers to easily spot bugs and source external tools. In addition, making immediate changes to the app is easier in Flutter.
Winner-Flutter is the winner
Flutter vs.React Native-Developer Productivity
React Native’s hot reload feature helps developers save big on time when it comes to UI testing. Further, the platform comes with excellent IDE support as developers can use any text editor or IDE of their choice. Even though Flutter comes with a hot reload feature, developers need to learn new Flutter concepts as the complexity of apps increases. Also, Dart is not a common language and as a result numerous text editors and IDEs don’t support the same.
Winner- React Native ensures better developer productivity.
Flutter vs.React Native- Learning Curve
Winner- When it comes to the learning curve, it is a tie between Flutter and React Native.
In this blog, we have highlighted the major differences between the two competitive frameworks . As with everything else, both frameworks come with their own set of pros and cons. Despite the fact that Flutter proved to be a better choice in almost every React Native vs. Flutter comparison,choosing between the two frameworks depends on several other factors like target audience, project goal, time and budget constraints.
