Flutter and React Native are the two most well-known names when it comes to cross-platform development frameworks. Both offer the ability to develop applications for different operating systems with a single codebase, which significantly reduces development time and maintenance.But what are the similarities and differences between React Native vs Flutter?
How does cross-platform app development work?
If you want to capture the attention of a large digital audience today, what do you do? One of the most effective answers is to offer an app. But how do you ensure that your app reaches as many users as possible, while also applying a simple development process?
The solution lies in using cross-platform frameworks. With these, you can develop applications for iOS and Android and potentially provide versions for MacOS, Windows, Linux, and the web simultaneously – all with a single codebase.
Although the use of cross-platform frameworks is becoming increasingly popular, there are different approaches and technologies. Each company has its own preferred tools.
Cross-platform app development: Is it necessary for your business?
The leading frameworks are Flutter from Google and React Native from Meta. Which one is best suited for your needs?This decision depends on some specific factors and will determine the future course of your cross-platform development. The goal of Flutter and React Native is to create a unified development process where a single codebase covers all relevant platforms. Before you decide between the two frameworks, you should consider why your company wants to use such a framework in the first place.
The main reasons for cross-platform development lie in the significantly shorter development time and the reduction of complexity during development. Companies wantto provide the best possible digital experience, but end users use a variety of devices and operating systems – including iOS, Android, MacOS, Windows, Linux, and the web – and they expect high quality across all platforms.
It is usually not an option to ignore important platforms, as it is worthwhile to reach the largest possible audience, especially when it comes to B2C applications. Your company could split the development team into several groups, each developing native apps for different platforms. However, this traditional approach is often costly and time-consumingand requires specific know-how for each individual target platform.
Switching to a cross-platform framework like Flutter or React Native solves these problems and offers numerous advantages:
- Better collaboration: All developers work with a single codebase, allowing everyone to pull in the same direction. This avoids functional silos and ensures that all platforms are equally maintained.
- Faster updates: Whether bug fixes or new features – with a single codebase, the development, coding, and testing processes proceed faster.
- Less maintenance effort: Maintaining multiple codebases can quickly become confusing. Managing a single codebase is more efficient and reduces the effort for bug fixes and updates.
- Improved communication: If the development team is divided into separate teams for each platform, differences in development styles and rhythms can complicate overall communication and slow down the development process.
- More cost-effective and faster development: Ultimately, the cost and time factor is a strong reason to opt for cross-platform development, as you only develop one application, not several.
This helps your company adhere to the roadmap for your app, respond to user feedback, quickly fix bugs, and deliver new features on time. So let's learn more about the two frameworks.
What is the Flutter framework?
Flutter is a modern and versatile framework specifically designed for developing cross-platform mobile applications. Developed by Google, Flutter is characterized by its high performance, flexibility, and user-friendliness.
Unlike traditional frameworks that are based on native languages like Kotlin (for Android) and Swift (for iOS), Flutter uses the programming language Dart. Dart is also a programming language developed by Google, designed for efficiency and developer-friendliness.
Thanks to Dart's reactive programming, Flutter enables rapid developmentof user-friendly interfaces while providing outstanding performance across different platforms. Additionally, Flutter's hot-reload feature allows for quick iterations and immediate feedback during development, significantly boosting developer productivity.
Overall, Flutter offers developers a modern and effective way to create cross-platform mobile applications.
Flutter and Dart are easy and quick to learn, especially if you come from a JavaScript background. The development documentation is excellent, the framework itself is consistently implemented, allowing you to derive much on your own over time without needing to look into the documentation.
The architecture is based on the very popular programming paradigm of reactive programming, following the same style as React. This allows for efficient and dynamic handling of GUI interactions and data flow in the application.
Flutter offers widgets from its own high-performance rendering engine. These are performant, visually appealing, and customizable. By using these widgets, Flutter apps can already provide a decent appearance and excellent user experience out-of-the-box.
Although you can still create your own custom app design by using existing UI elements that follow specific platform guidelines, Flutter makes it easier for developers to create a consistent and attractive user interface.
Overall, Flutter provides a powerful platform for developing mobile applications that is not only easy to learn but also offers high usability and customizability.
Perhaps the most important feature of Dart is that it is transpiled into machine code. From the unified Dart codebase, bytecode is generated that runs natively on the respective platform (Android, iOS, ...). If desired, source code in the respective platform language (Kotlin, Swift, ...) can still be added and interact with the Dart code. The ability to produce a natively compiled program on each platform is also one of the biggest differences from React Native:
What is React Native?
React Native is an open-source framework developed by Facebook that allows developers to create cross-platform mobile applications using JavaScript/JSX or TypeScript. React Native is based on calling native APIs of the devices and essentially provides the same functionality as a native app.
The React components are designed to wrap native code and work across different operating systems. The connection between native code and JavaScript occurs via a bridge module, which can lead to performance losses.
React Native is an open-source framework and welcomes contributions from its community. Thanks to the involvement of the React Native developer community, the framework has been able to extend beyond its iOS and Android roots. There is also the possibility to create Windows, MacOS, and web applications.
React Native vs. Flutter: Which is better for your project?
When deciding between React Native vs. Flutter for your project, there are a variety of factors to consider.
For both multi-platform frameworks, it is of course the case that whenever very good performance and intensive OS interactions play a role, development as a native app must be considered.
Regarding the question of whether Flutter or React Native is the best choice for you, the big difference should be mentioned again:
Flutter apps compile into the bytecode of the respective target platform.
A React Native app is merely wrapped. This step results in a loss of performance.
Flutter is therefore a good consensus of the discussed advantages it has when working with only one codebase, combined with more speed and deeper platform functionalities.
Advantages of Flutter
- Compiling into the code of the respective target platform offers better performance and more development possibilities compared to React Native
- Better suited for performant animations and highly-customized UI
- By using Skia/Impeller for the rendering engine, Flutter offers excellent performance, resulting in smooth and fast apps.
Disadvantages of Flutter
- Learning curve: Many developers are already familiar with JavaScript, but not with Dart (due to the syntactical similarity to JavaScript, learning Dart is certainly not rocket science)
- Smaller ecosystem: Compared to React Native, there may be fewer libraries and resources for Flutter, although this is constantly evolving.

React Nativeon the other hand, is based on JavaScript and benefits from a larger developer community than Flutter, as well as a greater abundance of libraries and packages. It allows for the integration of native features and offers solid performance, although generally worse than an app developed with Flutter.
Advantages of React Native:
- Familiarity with JavaScript: Developers who already master JavaScript can become productive with React Native more quickly.
- Larger developer community: The broad support from the developer community means that developers can more easily find solutions to their problems.
- Existing libraries: React Native has a variety of libraries and packages that can speed up the development process.
Teams often decide against React Native when the application to be developed:
- requires specialized background tasks, such as complex calculations, which cannot be efficiently performed with React Native.
- Hardware-near functionalities are to be exploited, such as Bluetooth communication, where there are often challenges with React Native.
- is only developed for Android, as React Native has a stronger supportfor iOS and developers often prioritize iOS platforms.
- As already explained above, React Native can have performance impacts.
In these scenarios, another development platform may be better suited.

A few more questions & answers:
Below we describe some frequently asked questions and answers about the topic.
Is Flutter a programming language?
No, Flutter is a framework in which applications are developed in the programming language Dart. Flutter to Dart is equivalent to React Native to JavaScript.
What are hybrid apps?
There are various definitions in use here. Often, mobile development distinguishes between native apps (explicitly written for Android or iOS), web apps (apps that run in a web browser), and hybrid apps – as a consensus solution between both worlds.
Hybrid apps have long been referred to as apps that use web technologies such as HTML, CSS, and JavaScript to create a cross-platform user interface – React Native is a prime example of a hybrid app framework.
Flutter apps do not fit into this perhaps somewhat outdated definition schema, as they do not use 'web technologies'. However, Flutter is also counted among the 'hybrid app frameworks', although the code actually produces a native app.
Hybrid apps in app development:
However one defines a 'hybrid app' - they are a central part of modern app development, as they allow developers to create applications that can run on various platforms and save a lot of time and complexity in software development, and be faster to market.
However, hybrid apps also have some disadvantages, such as potentially poorer performance compared to native apps and limited access to certain hardware features of the device. Additionally, they may sometimes be less seamlessly integrated into the operating system and not provide the same user experience as native apps.
Overall, hybrid apps are an attractive option for developers, who want to create applications for different platforms without having to write separate source code for each platform.
