Are you choosing between React Native and Flutter? Discover the difference between these two and what pros and cons they have.
The phenomenon of mobile apps dramatically affected the world of development. With over 3.6 mobile users worldwide, the creation of mobile apps requires new solutions that are less time and effort-consuming. In 2023, there are still two main hybrid frameworks for app development, Flutter vs React Native. And the popularity of both of them keeps rising.
42% of developers choose React Native for building apps, while Flutter is chosen by 39% in 2023. The third popular framework is Cordova that is chosen by only 18%! Flutter has already been used by over 2 mln of developers, and 500,000 use it monthly. The numbers are really impressive, but they mostly depend on the popularity of mobile apps among users. The matter is, 92% of mobile users spend time with apps and social media, and only 8% use web browsers. For business owners, presenting on all platforms is obligatory, and they won’t miss a chance to attract clients via various channels.
However, for most businesses developing native apps for each platform is an unbearable waste of time. Therefore, they are looking for some technologies that would help in developing cross-platform mobile applications. And here they start wondering what is better: React Native vs Flutter? Indeed, hybrid apps are the best solution for the business. The segment of hybrid apps is growing fast, and it seems that in several years, hybrid apps will displace native apps.
Nick, Tech Lead of Mobile Development department at NIX, says: “There are many tools and features that are equally good in React Native and Flutter: Code Reusability and Hot reload with its ability to make changes on the fly. Also, there are features that are equally bad, like stage management for instance. When it comes to performance, Flutter works without the use of additional APIs unlike React Native, and in fact, the framework does all of the work to connect the divide between the device and the codebase. When it comes to native appearance, React Native is more dynamic with a powerful and flexible API.”
So why are Flutter and React Native so popular? Obviously, native applications work better on mobile devices. Users with technical background will notice that graphic transitions take less time for UI rendering than cross-platforming. However, for a random user, the difference will be almost unnoticeable. Therefore, they start to consider Flutter vs React options.
All native frameworks employ code that speaks directly to the IS core. Nevertheless, the issue is that, depending on the OS and device, native frameworks are developed in various programming languages. As far as we are able to tell, at least two developers will be needed to create a native app for Android and iOS. But, the mobile world goes beyond just the OS. There are too many idiosyncrasies, which necessitate additional research and development, which costs more money.
To develop an Android app only, a company needs to hire Java, C, and C++ developers. For iOS, the developers with knowledge of Objective C and Swift must be hired. For small and medium businesses, it’s impossible to afford these costs. So why pay more if it is possible to choose between React vs Flutter, a cheap and fast way to build an app. In a nutshell, the list of hybrid app platform advantages contains the following aspects:
- Hybrid apps are more cost-effective. Developing an app on Flutter or React Native saves time, and the results are almost as satisfying as with a native app.
- They need shorter development time. Time is money. So when a company saves time of development, it additionally saves costs.
- They have offline support. There is no need to contact support anytime something is wrong with the code. Offline libraries have all answers. A developer just needs to know where to find them.
- Hybrid apps are easier to maintain. With all the updates of the systems, it may be difficult to track how the updates affect various codes. With hybrid apps, this is no longer a problem as you have one code for all applications.
- They run on both iOS and Android platforms. No need to spend more time and money on developing another app.
- They offer easy integration with third-party apps.
- Hybrid apps are often considered the best for an online marketplace. And it is true. The advantages are various, while the disadvantages are so minor that they can be ignored.
So why choose native app development if we can choose hybrid apps? There are two perfect solutions in cross-platforming development – Flutter vs React Native. They both possess a huge number of features, have open-source frameworks, and are powerful enough to develop almost any application. At this point, a new question appears: what is better for development, Flutter or React Native? In this article, we will try to find the answer to this question.
What is Flutter?
Flutter is an open-source framework by Google for building beautiful, natively compiled, multi-platform applications from a single codebase. Developed by Google it was first released back in 2017.
Nowadays it continues its rapid growth and becomes more popular in the developers’ circles. If we compare React Native vs Flutter 2023 stats, we will notice that Flutter has become more popular among developers. Even such exotic IT regions as Kenya, China, Bangladesh, Japan, and Jordan choose this framework. Compared to previous periods, when 30% chose Flutter, in 2023, this number keeps growing.
What’s so special about Flutter? First of all, it is the ability to create cross-platform applications using a single codebase. It means that there is no need to develop separate apps for the web, mobile, and desktop. With Flutter, there appears one single tool that helps to develop apps easily.
Todd Fabacher, Chief Executive Officer with over 25 years history of working in the computer software industry, says about Flutter: “This has been attempted many times before with moderate success, but Google has finally solved the mobile development puzzle with Flutter. It is open-source and free, which is perfect for students and others on a limited budget. My advice is just to download it and get started. It is that simple. It will be the best investment in yourself or your company that you will ever make.”
No more compromises on speed, quality, or performance – Flutter helps to build beautiful apps within a single codebase. Flutter consists of a framework built with Dart. The rendering engine is designed predominantly in C++. It’s interesting to know that apps built using Flutter are more intuitive and easier to navigate. The matter is that with this framework, app developers can modify UX. This process requires changing the variable in the state. In React Native vs Flutter comparison, this point is extremely important.
On March 2, 2021, Flutter 2 was announced by Google. The news is fascinating, as this update fundamentally shifts the way developers build apps. It uses a codebase for 5 OS: iOS, Android, Windows, macOS, and Linux, and additionally, it targets such browsers as Chrome, Firefox, Safari, and Edge. What does it mean for the developers? Flutter finally can help in building apps for the web!
According to Google, “Flutter’s web support builds on these innovations, offering an app-centric framework that takes full advantage of all that the modern web has to offer.”
Although Flutter belongs to one of the fastest cross-platform frameworks to build an app, the speed of development is lower than in React Native. The matter is that when working with Flutter, it’s important to add different code files for Android and iOS systems. However, it happens only when an app requires more complicated UI elements. However, Flutter has and access to several third-party UI libraries with ready-to-use components. Due to this, the development time can be decreased. And to tell the truth, these libraries make the development process more convenient.
Another great point about Flutter is Hot Reloading” or “Hot Restart.” Due to these features, a developer can see all the changes instantly.
- Performance optimization in with tree shaking and deferred loading
- Performance improvement with image placeholders, precaching, and disabled navigation transitions
- Creating Flutter widgets that perform
Controlling build costs, employing effects and widgets only when necessary, aplpying lazy methods for lists or grids, creating and showing frames in 16ms are some recommendations made by Flutter. We should be aware that Flutter does not perform better than React Native in terms of performance. However, many developers admit that Flutter has too many other advantages, which make it a better choice.
The documentation for Flutter is renowned for being highly organized and having all the answers. Despite the low speed of the development, many still prefer Flutter due to the documentation. Perhaps the only drawback of Flutter documentation is that you must visit a website each time you need to check something. From a different angle, the website’s documents are so thoughtfully organized that the problems are hardly evident. Open source has Flutter documentation available docs.flutter.io website. Flutter documentation covers but is not limited to:
- Core Encoders and decoders for converting between various data representations, built-in types, collections, and other (support for asynchronous programming, classes and utilities augmenting the collection support in dart:core, support for asynchronous programming, and other core functionality for every Dart program, etc.)
- Foreign Function Interface, I/O support for files, sockets, HTTP, and other protocols for non-web applications, and concurrent programming using isolates are all included in the virtual machine (VM).
- Platform_integration(Android and iOS)
You can find everything you need about Flutter in the documentation. However, some developers say that despite a huge variety of information, the Flutter library is still not so well-structured as the library of React Native. Again, this is where Google Flutter vs React Native compete, but the winner is still unknown.
It might take a lot of work to create user interfaces that are both attractive and useful. The entire process of creating apps is transformed by Flutter. You may kickstart your projects and accelerate your development process with the help of the extensive library of code snippets and app templates offered by Flutter UI. You may create apps with the Flutter UI toolkit & SDK. You can utilize Flutter, which is free source, to create extremely effective desktop and mobile applications. Go through all the advantages of utilizing Flutter with us so you can choose whether to use it for your upcoming project. With a single codebase, create, test, and publish eye-catching desktop, web, mobile, and embedded apps.
The simplicity with which widgets can be changed or customized when utilizing Flutter is one of its advantages. Moreover, it offers UI widgets that adhere to important web application design standards. The open-source framework Flutter has attracted a substantial and active development community since its release. With a single codebase, developers can create stunning, natively built mobile, web, and desktop applications using Google’s Flutter UI toolkit. Flutter is free and open source, integrates with existing code, and is utilized by developers and businesses all over the world. Because it doesn’t rely on web browser technology or the collection of pre-installed widgets on every device, Flutter differs from most other frameworks for developing mobile apps. Instead, Flutter draws widgets using a powerful rendering engine that it has especially developed.
The goal of Flutter Community is to offer information and resources for everything relevant to Flutter. Regardless of skill level, every developer may find information on our YouTube channel, which features weekly office hours and Flutter hackathons. Internet address: https://fluttercommunity.dev. There, Flutter offers to everyone an inclusive community. Join the global community of developers to improve Flutter or take on a leadership role, contribute to the Flutter ecosystem. You will benefit from your leadership as you access exclusive resources there.
Pros and cons of Flutter
Like any other framework, Flutter has some advantages and disadvantages. However, the decision on what framework to use is up to the developer. To make the right choice, it is important to compare react native vs flutter performance and understand what you like more.
Pros of Flutter
We’ll start with the pros that make Flutter the best choice for the developers. Here’s the list of advantages of Flutter over React Native:
- It looks great!
- It’s rich in widgets;
- The community is rapidly growing
- Well-structured documentation
- Permanent improvements for web development
- It requires less testing
- The apps are fast
- It helps to create the same UI for older devices
- Flutter 2 helps to build apps for the web!
A relatively new toolkit called Flutter makes it simple to create cross-platform apps that look amazing and are simple to use. We’ll create an app that works on both iOS and Android and looks and feels like it was created natively by employing a platform’s native components.
Cons of Flutter
Even though the list of Flutter advantages is impressive, some disadvantages are still important to consider.
- It is not native
- The apps are bigger than native ones
- It still has a limited set of tools and libraries comparing to native apps
These disadvantages are minor, and they do not interfere with app development. However, in some cases, the cons of Flutter may be decisive when choosing a cross-platform development framework.
What is React Native?
Tom Occhino, Engineering Manager at Facebook, told about React Native: “Engineers are choosing to use React every day because it enables them to spend more time focusing on their products and less time fighting with their framework. It wasn’t until we’d been building with React for a while, though, that we started to understand what makes it so powerful.”
Today, React Native has a big community which makes it the most popular cross-platform development tool. The poll found that 42% of developers worldwide used Flutter. The majority of mobile developers use native tools, with only around a third using cross-platform technologies or frameworks. Flutter’s popularity is so undeniable and will grow much more in 2023.
React Native is known for its fast development time and access to a few third-party UI libraries with ready-to-use components that allow saving time during the development. Also, it enables delivering new functionalities to supported platforms immediately, which also requires less time. Like Flutter, React Native possesses several features that simplify and speed up the development process. For example, it also has a Hot reload feature. It means that a developer can make instant changes and see the results immediately.
React Native is easy to install, but unlike Flutter, it creates packages. Some developers find it annoying, but for many, this plays any importance. React Native provides only UI rendering and device access APIs. It means that the framework relies on third-party libraries. And it depends on them. In this Flutter vs React comparison score goes to Flutter. So which is better Flutter or React Native, from the perspective of development? It seems that React Native has the score.
If we compare flutter and react native, React Native documentation is not so impressive, but many developers find it more user-friendly. It includes guides and popular topics, so you can always find everything that you may require. Basically, it covers:
- Core components and native components
- React fundamentals:
- Handling Text Input
- Using a ScrollView
- Using List Views
- Platform-Specific Code
- Environment setup:
- Setting up the development environment
- Integration with Existing Apps
- Integration with an Android Fragment
- Building For TV Devices
- Out-of-Tree Platforms
- Running On Device
- Fast Refresh
- Symbolicating a stack trace
- Using Libraries
- Using TypeScript
- Upgrading to new versions
- Height and Width
- Layout with Flexbox
- Color Reference
- Handling Touches

- Guides (Android):
- Headless JS
- Publishing to Google Play Store
- Guides (iOS):
- Linking Libraries
- Running On Simulator
- Communication between native and React Native
- App Extensions
- Publishing to Apple App Store
You may start developing your app right away using the necessary, pre-built Native Components that come with React Native. These are the Essential Components of React Native. There is a ton of native UI widgets available like Native UI Components for Android that are ready to use in the newest apps; some of them are included with the platform, some can be found as third-party libraries, and still more may be utilized in your own portfolio. There are several React NAtive libraries worth trying:
- React Native Paper
- React Native Elements
- React NativeBase
- React Native UI kitten
- React Native Material Kit
React Native doesn’t have too many UI libraries like React or Vue or Node JS. Every library mentioned above has almost 5K of Github stars and a decent team size community to handle any issues raised on Github. If you have worked with all of the libraries on professional and personal projects, you will know that they fit really well. Integration or getting started with each of them is quite easy, so that’s a huge plus to using Flutter for your UI.
Pros and cons of React Native
Both Flutter and React Native have some peculiarities that make them more or less attractive. Here, we will dwell upon the pros and cons of the RN. Netguru presents their vision on pros and cons of React Native:
Pros of React Native
If you are still hesitating whether React Native is worth your attention, the advantages will help you make your mind:
- It has a Hot Reload feature, which helps with fast coding
- One codebase that helps to create apps for two and more platforms
- The code can be reused
- It has an active and supportive community
- If you hire Reactjs developers, they easily learn React Native
- It saves up 50% of the time on testing
- It has fantastic performance
Nader Dabit, Developer Advocate, AWS, defines the following pros of React Native:
- Faster speed development
- Lower cost of development
- code reuse
- easier to find developers
- Ship across multiple platforms
- Possible to ship over the air updates bypassing App Store / Play Store.
Cons of React Native
Although there are many advantages, there are still some disadvantages in React Native usage. Here they are:
- Still, it is not native
- It does not have many out of box components
- The choice is limited
- Abandoned packages and libraries
- UI can be easily broken
- Apps are bigger than native ones
Disadvantages of Flutter vs React Native have many things in common. The matter is that they both are not native, and this implies some problems to the development. However, with proficient support and libraries, all disadvantages become minor. We recommend comparing the advantages and disadvantages of Flutter and React Native to find the points that are important to you.
Key differences between Flutter and React Native?
Flutter has very brief documentation for the developers who are from other platforms like Android, iOS, React Native, or Web. However, mobile, web, or desktop development is not required to learn flutter. In the case you have experience in developing applications for other platforms, then you may study flutter documentation and learn very fast.
To start a project you need to download the installation package as a flutter.zip file with the stable version of the Flutter SDK.
We can do this with the following line:
curl -O https://storage.googleapis.com/flutter_infra/releases/beta/macos/flutter_macos_v1.12.13+hotfix.8-stable.zip
Add the flutter tool to your path:
You can see if there are any dependencies that need to be installed to complete the installation with the following command:
We can then create and run a new Flutter app by executing the following from the command line:
flutter create flutter_list
open -a Simulator // if you don’t run simulator
That’s it, we’ve successfully launched our Flutter app.
The React Native documentation rather discusses components, APIs, and topics that are specific to React Native only.
React Native can be installed via the node package manager. If you use macOS, work with HomeBrew. If you don’t have HomeBrew, you should install it.
Let’s install it with the following command:
$ /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
After installing Homebrew:
brew install node
brew install watchman
npm install -g react-native-cli
Now we can access react-native from the command line. Let’s create a new React Native project called react_native_list:
react-native init react_native_list
react native run ios
That’s it, we’ve successfully launched our React Native app.
Dynamic vs. static programming
There exist two major differences between dynamic typing and static typing. You need to be aware of them when writing transformation scripts. First, dynamically-typed languages perform type checking at runtime, while statically typed programming languages perform type checking at compile time. Java script that is used in React Native is considered a dynamically typed language. Unlike, Dart, which is used in Flutter is statically typed. With its combination of static and runtime checks, Dart has a sound type system, which guarantees that an expression of one type cannot produce a value of another type. For more information, read about Dart’s type system.
In terms of a project size Flutter may need 2 GB of available disk space minimum, 4 GB Recommended (500 MB for IDE + 1.5 GB for Android SDK and emulator system image. The app size may averagely take in android go devices up to 60mbs just for default app in Flutter new project. This is normal for flutter due to additional necessary files, etc.
Comparatively, React Native app size, for example, may be reduced from 26.1 MB to 3.1 MB, which makes it a recommended framework for mobile app development, though very hard to debug, etc.
The Dart framework uses the Skia C++ engine which has all the protocols, compositions, and channels. Flutter has everything you need to develop applications in the Flutter engine itself.
So our project may look like this:
Where may be such project attributes as:
Android is a native Android app project that runs and builds our Flutter project;
ios is xcode is the iOS project that is used when building the Flutter iOS app;
lib is the main folder where the code of your Flutter application is stored;
pubspec.yaml is a project configuration file that you will often use when working with project settings. If you want to add a library, you will use this file.
Flutter and React Native Apps Examples
What apps are made with Flutter? Here you will find some of the most popular ones.
Applications are written in Flutter:
- Google Ads.
- Hamilton Musical.
What apps are made with React? Accordingly, here are some of the apps you know that are made with React.
Example apps in React Native:
Here’s some comparison made by Desuvit for you to consider the differences when coming up with apps development ideas:
Also, when you look through the Flutter dev docs you will be able to see the difference in the code. Everyone who is familiar with object-oriented code and basic programming concepts such as variables, loops, and conditionals, may complete this tutorial. Here are some Flutter app code samples:
After pasting the code into your app, you may get something that looks like this for a start:
React app coding has its peculiarities. In React there are several ways to declare components, However, that does not make it harder or less flexible than Flutter. Just mind some syntax and usage differences. Here’s a React Component Example retrieved from Freecodecamp:
This Flutter app may provide the user with detailed insight into how their days are going and also give valuable insights from leading self-help experts to assist people in coping with any mental health issues, etc.
Google Pay app – Google
Google once asked a team of people who had previously worked on native apps to build their new project with Flutter. So, that’s how their first app was made in Flutter and became Google’s cross-platform technology.
The most popular network with breaking news on world finance, business, stock market and investments., giving you access to award-winning journalism to help you understand the economics, and more was built in React Native. You can monitor your portfolio and securities that matter to you accessible in the app, giving you increased flexibility and efficiency.
This is a worldwide known social network tat was designed to connect with friends, family, and other people you know to share photos and videos, send messages and get updates, and more. Nowadays its widely used to launch promotion campaigns via creative ads. Built as an efficient and safe mobile app in React Native.
The future of Flutter and React Native
Applications written on the React Native platform are somewhere in the middle between native and hybrid. We can say that this framework represents the future of mobile application development and makes the border between native and hybrid development more transparent. It translates the application code into machine language and provides a native look and feels for mobile applications.
There are several reasons for the global success of React Native. First, with React Native, companies can only create code once and use it to power their iOS and Android apps. This means huge savings in time and resources.
Flutter is a relatively young but very promising platform that has already attracted the attention of large companies that have launched their applications. This platform is often attractive for its simplicity compared to the development of web applications and the speed of work on a par with native applications.
There is an idea that currently, all cross-platform frameworks do not focus on optimization and application performance, but rather on beauty and all possible beautiful animations. This side can also be understood because the main task of such platforms is to create a beautiful and convenient interface for the user, and take care of speed and performance is not the first thing. Applying Flutter changes everything. The future of cross-platform mobile development is behind this platform, such as the Chinese global app Alibaba.
Since Flutter apps are compiled to native code using graphics and rendering engines built into C/C++ and has high speed, that is why such applications are fast and reliable. In the field of cross-platform technologies, this gives Flutter an obvious advantage over competitors in the future. The platform is developing rapidly, and Google is investing a lot of effort and funds into its growth. The future of cross-platform development is behind the Flutter platform.
React Native may be a great tool for MVP, but when the application gets big and cool, you still need to rewrite a lot to native code. Sketching the same UI is much faster than on iOS. Some developers admit that difficulties begin with pixel-perfect and specific support for various devices. A big plus is that the architecture is determined so they don’t need to think about using MVC, MVVM or VIPER every time. And there are enough pluses and minuses, but on React Native they can do both well and quickly.
Flutter vs React Native: Summary Comparison
As we can see now, Flutter and React Native have many things in common. First and foremost, they are both open-source frameworks that anyone can use. They both are developed by leading companies: Google created Flutter vs React Native was created by Facebook. To compare basic info about Flutter and React Native, you can check this info by NIX.
React Native has been a hot topic, especially in the mobile development world for a while. No wonder – it took the world of technology by storm, offering a way to develop mobile applications for both iOS and Android at the same time. React Native is a single framework to manage them all. It has been successfully adopted by hundreds of companies around the world, including Uber, Microsoft, and Facebook, and is used by many more. However, before you decide to go all-in with React Native, it’s very important to understand how it works and determine if it’s a better fit for your project.
Flutter is easier to use as it is more resistant to system updates. It means that when iOS or Android update the OS, the app will remain the same. On the contrary, React Native depends on native elements, so when the update is released, some problems may appear in the launch app. Currently, Flutter supports Android 4.1+ or iOS 8+, while React Native supports Android 4.1+ and iOS 10+.
The biggest difference between React Native and Flutter is that Flutter has plugins developed by the Google team, like geolocation and mapping. Unfortunately, React Native app works better with apps with a one-time location and does not require tracking.
All in all, Flutter and React Native are great choices to save time and money on mobile app development. What framework to choose will depend on the preferences of the developer and the company.
