If you have a great application idea, you might be thinking about what could be the best way to bring that idea to life. You might think of using native SDKs but that is time and cost-consuming as you will be coding twice, for both Android and iOS. Because depending on the OS and device, you’ve to write native frameworks in different languages. So, in case you cannot afford to hire two different flutter developers teams for your app, your best option is to use a cross-platform SDK. The two most popular hybrid frameworks designed for this purpose are in close comparison: Flutter vs React Native.
Both are free, open-source frameworks offering a large variety of options. They are also growing continuously and coming up with new updates to overtake the competition. So which of these cross-platform solutions is the best option for you? We have compiled a brief list of key differences between the two to help you make an informed decision.
Flutter vs React Native – Key Differences
When it comes to Flutter app development Services, there is no compromise on quality, speed, and performance. And along with Android and iOS, Flutter has also extended its support to Linux, Windows, macOS, Fuchsia, and web app development. React Native, created by Facebook, supports cross-platform app development on mobile, web, and desktop. But React Native has a huge advantage because of the programming language it uses – Java Script. Since it’s a common language as compared to Dart, developers find it easier to shift to React Native. Moving towards the comparison of Flutter vs React Native, you can consider the following points for your app development.
Dynamic vs Static Programming
The two SDKs share numerous similarities, but the core difference between the two is the programming language. Dart, used by Flutter, is a statically typed language with a little perk of dynamically typed languages. JS on the other hand is dynamically typed. Now there are two major differences between dynamic and static typing.
The first is that a dynamically typed language performs type-checking during the runtime. Whereas a statically typed language performs type-checking during the compilation, making it a much safer option. So, with Dart, you can enjoy a sound-type system with its combination of static and runtime checks. This assures that an expression of one type cannot produce a value of another.
Development Tools and Documentation
React Native was launched in 2015 so it has more maturity than Flutter. As a result, it has excellent documentation for app developers. But it isn’t straightforward and some important features like navigation are not structured properly. Flutter’s documentation is brief but rich, well-formatted, detailed, and structured. It is also much easier to navigate.
React Native is not that detailed as its major focus is on mature developers. But Flutter’s guides accompany video tutorials as well as graphics so that even a beginner can learn it fast. Furthermore, Flutter has several development tools for your assistance in app development, including Flutter inspector and debugger.
Flutter, however, communicates directly with the native components. Because it has everything packed in itself including frameworks like Material Design and Cupertino. Because of this advantage of Flutter app development, Flutter apps are more stable on different platforms.
Regarding project size, Flutter needs a minimum of 2GB of available disk space. And since Flutter has a large build size, the default app size can exceed 60MB. Meanwhile, the size of React Native apps can be reduced from 26.1MB to 3.1MB by enabling ProGuard and Hermes. This makes React Native a preferable option for mobile app development.
Productivity and Code Reusability
Both Flutter and React Native share the feature of Hot Reload (Fast Refresh in React Native), allowing you to make quick iterations and get updates easily. This speeds up the development process. Additionally, React Native has high code reusability and its dev community has also built a lot of libraries that serve as building blocks. Flutter’s libraries may not be as rich but it offers faster compilation and less testing time. Flutter also contributes to code reusability through its highly graphical and intuitive user interface.
The process of debugging can be quite complicated in React Native. This is one of the aspects that makes it less desirable for developers. Debugging can get more problematic if there is an error or a specific exception to the native part of your application. Because on the native side, there is a chance that the bug can come from React Native or third-party libraries. The users of React Native prefer to use Flipper for debugging mob applications.
In Flutter, you can use Flutter Inspector which will help you debug the visual layer of your application by showing why it looks the way it does. Also, Flutter provides the aid of different debugging tools like DevTools and OEM Debugger that support app development in Visual Studio and Android Studio.
Packages and Libraries
Comparatively, React Native’s ecosystem is bigger than Flutter’s because of its repository of packages – node package manager (npm). Npm has been around for a long time and it is mainly geared around web development. You can also adopt some of the libraries to React Native apps. However, there is a downside here. Many of the available libraries are low quality and barely useful in production while some packages have been abandoned altogether. So you have to tread carefully.
Flutter’s Packages pub-dev, although quite young with fewer read-made solutions, has grown enormously since its launch. Since June 2022, Flutter stands at 389,762 repositories and the launch of Flutter 3.3 has further expanded this repository. Whereas React Native has 300,521 repository results.
Community Size and Support
Both Flutter and React Native platforms have the support of huge and flourishing communities – Google and Facebook respectively. The communities conduct their annual conferences, events, and hackathons regularly. The platforms have a huge community size and communication channels where there are experts to tackle your questions and provide development solutions.
From the 2022 update, you can notice that Flutter’s community has grown a lot. This means that there are now more developers and experts working actively to improve app development for its users.
Comparison of Demand
Flutter has been a part of the tech stack of companies like:
React Native has been a part of the tech stack of companies like:
- Uber Eats
So what is the global trend in the demand for Flutter vs React Native?
After staying at the bottom of the popularity list in 2019, Flutter gained popularity and managed to stay in close competition with React Native, overtaking React Native in 2020. In 2021, Flutter secured its position as the leading cross-platform for mob app development and surpassed React Native by 4%. So, we can say that even though the two technologies are almost equal in demand, Flutter has been gaining more popularity recently.
Comparison of Performance
Considering a developer’s perspective it is easier to learn Flutter than React Native. How?
Well, as compared to Dart, JS is much unfriendly with its unnecessarily complicated programming. Furthermore, the framework has some nuances, and without being familiar with it, you would end up wasting hours trying to configure the developer environment.
On the other hand, Flutter’s framework is easier to navigate and developer-friendly. Flutter’s programming language, Dart, is also easier to understand and work with, as compared to JS. Also, Dart is closer in its usage and paradigm to languages used in native app development.
Flutter vs React Native – Developers’ Rates
One of the key challenges you will face when developing your app is hiring a developer. The decision mainly relies on your budget. According to Glassgow, Flutter developers roughly take $100,000 per year for app development. To hire a React Native developer, however, you will have to spend $108,000 per year. Thus, when it comes to hiring Flutter vs React Native developers, the cost of hiring a React Native developer is higher.
When to Use Flutter
Flutter app development should be your priority when:
- You have a packed budget and you cannot afford to hire separate developer teams for different versions of your app.
- You want the product to be delivered on short notice, as flutter apps take less time to develop and have quick market time.
- You want a cross-platform experience for your web app users.
- Flutter apps are more resistant to OS updates and you won’t find any problem in the launch app.
- You want a pixel-perfect design with a highly-interactive and user-friendly UI.
When to Use React Native
React Native app development should be your priority when:
- You have a web or desktop app and you can reuse the components to create a mobile app.
- You already have a team of JS who is familiar with your existing assets and can use the modules, widgets, and plug-ins accordingly.
- If your company is already using React.js in its web apps or websites, then you should use React Native. Because it gives you the advantage of sharing code between multiple apps and will reduce your initial development time. Additionally, code sharing also simplifies long-term maintenance.
All in all, both Flutter and React Native are great choices for mobile app development and they allow users to save both time and money. If as a developer you have just taken a start, then we recommend you to make some attempts with Flutter as well because the platform is gaining popularity rather quickly.
