Let’s now dive into the details of Flutter development and move to React Native straight after.
What is Flutter?
Fully released in 2018, Flutter is much younger than React Native, yet it’s already taken the UI development world by storm. Flutter is an open-source mobile app development framework created by Google. It allows developers to build high-performance mobile apps for iOS and Android using a single codebase written in the Dart programming language.
Cross-platform app development in Flutter
Flutter has a large and growing developer community and a strong ecosystem of packages and plugins that can be easily integrated into your project. The framework provides a rich set of customisable widgets, allowing you to build expressive and high-performance user interfaces for iOS and Android apps.
Furthermore, Flutter supports the hot reload feature letting you see the code changes without reloading the entire application. Developers also evaluate the Flutter documentation as easy to read, well-structured, detailed, and formatted, contributing to the smooth process of building apps in this cross-platform framework.
One codebase, 2 mobile applications (and more!)
Flutter framework is platform-agnostic since it has its own widget design so that you can use an app on multiple platforms (and it’s easier for you to differentiate apps, update and add new features). Furthermore, today Flutter supports six platforms, including:
- and the web.
All of that while maintaining a native-like user experience as with native components.
A glance at Flutter app performance
Flutter is known for its high performance, as it uses a reactive programming model, which allows for smooth and responsive animations and transitions. Additionally, the framework uses its own built-in widgets rather than native components, which can improve performance by reducing the amount of communication between the app and the underlying platform.
Flutter also has a lightweight and fast Dart runtime, which allows apps to start and run quickly. Moreover, the “Ahead-of-Time” (AOT) compilation pre-compiles the Dart code into native code, reducing the amount of processing required at runtime. All of that contributes to smooth and quite easy cross-platform application development.
The Flutter engine is designed to provide high mobile and web apps performance. The engine is written in C++ and uses Skia, an open-source 2D graphics library, to render the user interface.
What is really so distinctive about Flutter?
Since Flutter 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 developed.
Flutter is also unique since it just has a thin layer of C/C++ code. Most of Flutter’s system (compositing, gestures, animation, framework, widgets, etc.) is implemented in Dart, a contemporary object-oriented language that is simple to understand, modify, replace, and remove for developers. This greatly reduces the barrier to entry for most of the system and provides developers immense control over it.
What apps are built with Flutter?
Many well-known brands have developed their application with this cross-platform Google framework, including:
- Google Pay
- eBay Motors
- and many more! See it yourself:
One of the first Flutter projects: the Topline app by Abbey Road Studios, was run by Miquido developers. Check its detailed case study and a list of the top apps built with Flutter!
React Native: The Basics
React Native app development
React Native framework has a large developer community and a strong ecosystem of libraries and tools. Third-party UI libraries with out-of-the-box components can save you a lot of time.
React Native also allows you to immediately deploy new features on supported platforms, which takes less time. During the native development, the hot reload feature allows React Native developers to see changes as soon as they are made, saving a lot of time.
What’s more, the implementation time and the Quality Assurance in React Native mobile development are quick, efficient and accessible. They enable react native developers to use any integrated development environment (IDE) or text editor to edit, build and test the software when creating mobile apps.

The main differences between Flutter and React Native
As mobile app development continues to grow, various frameworks and technologies are available for companies willing to create their digital products. Flutter and React Native both offer the ability to create high-quality, cross-platform applications. However, several key differences between these two frameworks can influence the final choice. Let’s now explore the main differences between Flutter and React Native, including their programming languages, architecture, performance, and more, to help you make an informed decision when choosing a mobile app development framework.
Development speed and maintenance of the mobile apps
One of the most important things about React Native mobile app development is that it uses native UI components. This comes with a certain risk: when a new version of the operating system is released, it may break the interface of your application.
When you’re working with React, you need to remember that it might need extra maintenance in the long run. On the other hand, any native updates (e.g. changes in navigation gestures) will be applied automatically in React Native applications. In the case of Flutter, you need to implement them manually.
Flutter as a better fit for your MVP
Flutter prides itself on increased time-to-market speed. It has its own rich library of components for ensuring a smooth cross-platform development even in a few weeks. These can be applied across different platforms and operating systems.
The developers don’t need to write platform-specific codes, which reduces the number of working hours needed for development. This is a huge advantage for the business! In other words, Flutter can significantly reduce the costs of the cross-platform development process.
Moreover, Flutter was primarily designed for fast development of user interfaces based on Material Design rules. If this is what you’re after, using Flutter will surely speed up your work.
Behind the React Native slowing down aspects
React Native doesn’t come with its own library of widgets – you need to use third-party libraries instead. This may slow down the development process. On the other hand, React works really well for creating customized user interfaces. It might be better for you when you often work with custom solutions.
It’s also important to note that both Flutter and React Native support reusable code, yet there is one noticeable difference. Flutter developers can overwrite particular parts of the code, while React Natives require more adjustments. Again, Flutter proves to be a better time-saver – and time is money, isn’t it?
Cross-platform apps performance in React Native vs Flutter
On iOS, React Native apps appear to be significantly slower than Flutter. If you’re looking to develop something super swift, Flutter will make a better pick.
React Native vs Flutter app size comparison
Flutter apps are typically “bigger” than React Native ones. The main reason behind it is the C/C++ engine. It’s important to note, however, that React Native apps are still relatively big. No matter which one you choose, every mobile app development framework will make the app a bit bulkier.
Regarding the impact of size on performance, Flutter’s bigger apps are typically faster. All the features that take up place make the app faster in the end. React Native is trying to keep up with the help of dedicated engines, such as Hermes.
Debugging in Flutter vs React Native
Both React Native and Flutter are simple to debug. React Native uses React Native Debugger, a powerful debugger for React Native that integrates with Chrome DevTools.
React Native has a huge community behind it, and there is always someone who can help us find solutions.
Flutter uses Flutter Doctor, a command-line tool for diagnosing and fixing problems with your Flutter installation. In addition to this, Flutter has pretty simple syntax, which helps while debugging.
Built-in components: React Native relies on native components provided by the underlying platform, which can lead to inconsistencies in the look and feel of the app across different platforms If we don’t style components in our own styles. On the other hand, Flutter provides its own set of built-in widgets designed to be fast and consistent across all platforms.
Reusability: React Native components are typically reusable across different platforms, but the look and feel of the components may need to be adjusted for each platform. Flutter components are designed to be highly reusable, with a consistent look and feel across all platforms.
Development documentation aspects
The React Native documentation and the huge community behind the framework are its strong suits. You can always ask someone for advice when running a react native project. Of course, Flutter has a rapidly growing base of developers as well. It’s safe to say that both frameworks are doing quite well in this area.
Pros and cons regarding code reuse between Flutter and React Native mobile platforms
React Native has an API set which is useful on both iPhone and Android devices. While many developers using React Native initially build their app on one platform before importing it to another platform, it’s also possible to write shared components between iOS and Android apps. Flutter apps can be written on platform-specific platforms; therefore, there is no sharing between the applications on an Android or iOS device. However, there are library providers that help make use of existing Native Content easier.
Learning curve difference for Flutter vs React Native developers
This is another thing worth considering when choosing the right framework. When your team is already familiar with either React Native or Flutter, it’s always an extra cost if they’re supposed to learn another language.
Flutter Developers vs React Native Developers rates comparison
The main difference between Flutter and React Native developers is the salary gap between various development levels. Among other things, a young mobile developer earning around 36K a year varies by company and project, while senior developers get above 80K. Usually, European countries have relatively lower software engineering costs than the US but higher than the South Eastern countries.
Main advantages of Flutter
Flutter is easier to scale across different platforms and operating systems, as all UI components remain the same. This means that the user interface will look the same on iOS and Android. Because of that, you’re also less likely to face compatibility issues on different versions of the same OS.
Another huge advantage is both the speed of development and the app itself. If a high tempo is what you need, Flutter is sure to meet your needs.
Even up to 50% less testing in Flutter
Since there are two versions of the same application, the quality assurance process is faster because it allows more testing. We can run a similar test on two platforms, reducing our QA workload by 50% and reducing QA time. However, you will still need to do manual testing in the same fashion as for native programming – since QA specialists will have to manually examine both applications for each platform.
Main advantages of React Native
Sometimes it’s also an exclusive option when you need a very specific solution. If you have to create a stable biometrics authentication process or integrate with a KYC (know your customer) service, React Native is probably your only choice.
React native vs Flutter: which is better for your mobile or web app?
Down to the big question: which one is better, Flutter vs React Native? To be completely honest, we’ve got a really close tie here. To briefly differentiate them, React Native is geared toward web developers, whereas Flutter is targeted towards the group of native app developers. However, the answer depends on your resources and the apps you want to develop. While React Native has been around longer, Flutter is an exciting (and usually swifter) newcomer.
We hope that this Flutter vs React Native article will help you compare these two frameworks and give the first support when deciding which one to choose for your next app development project.
