Flutter vs React Native: Which is Best for App Development?

During the early days, developing mobile apps for multiple platforms meant maintaining two separate codebases for Android and iOS. The approach was time-consuming, expensive, and demanded more resources than other methods. At that time, it seemed impossible to deal with the issue and develop a single application for multiple platforms.

To tackle the issue, Facebook launched React Native to empower developers to build natively rendered mobile apps using the feature-rich React library. It gained immense popularity for enabling developers to deploy apps across both platforms after writing code once. It also delivered near-native performance.

On the other side, Google launched an open-source framework Flutter, solving the same problem with a different approach. Flutter used a single codebase written in Dart to create apps that could run across many platforms, including Android, iOS, etc.

Both technologies have resolved a troublesome issue. However, Flutter vs. React Native, which one to pick for development, has become a difficult choice even for experts. To make the choice easy for you, we have crafted this blog, primarily focusing on these two frameworks.

So here we are with the Flutter vs. React Native comparison. We will guide you to choose the framework that aligns best with your project’s unique requirements, development team’s expertise, and long-term vision.

However, there are various reasons for this change, and they do not indicate much about the popularity and usage of both frameworks. That’s why we will do an overview of Flutter vs. React Native to find out which is better than the other one.

Basic Comparison

flutter vs react native comparison

Performance Analysis

Flutter is written in Dart and complies directly with native ARM code. It has no interconnecting bridge to initiate interactions with native components. The feature boosts Flutter’s performance and lowers development time.

React Native uses JavaScript to connect with native components via a bridge. It affects React Native’s performance and development speed.

So, when it comes to performance, Flutter has an edge over React Native due to its complied-to-native code approach.

User Interface and Design

Flutter works with sets of highly customizable widgets to enable developers to create custom and complex UI designs. These widgets are regarded for their flexibility in achieving pixel-perfect designs. Moreover, Flutter uses its own rendering engine to create UI components that help achieve a consistent look and feel across different platforms and maintain a uniform user experience.

React Native utilizes native components that leverage the platform’s native UI elements, like UIViews on iOS and Views on Android. These components offer an authentic look and feel of native apps. Along with it, React Native allows you to access platform-specific customization options easily. You can also use its third-party libraries and UI component packages, enhancing the UI development process.

In this comparison, the victory of a framework is subjective to use cases. Choose Flutter if you want to build highly customized and consistent UI across platforms while maintaining design flexibility and don’t want to rely on platform-specific UI components.

Choose React Native if you need a highly authentic native look and feel or if your project requires strong integration with platform-specific UI elements and device features.

Development Speed

Flutter’s hot reload feature, single codebase approach, and availability of highly customizable widgets simplify and speed up development. Developers have to add different code files for iOS and Android systems if the app has complicated UI elements. The practice demands time and makes the development process lengthy.

So, compared to React Native, Flutter is slow in terms of speed. That’s because React Native has a vast ecosystem of third-party libraries, native modules, ready-to-use components, and many other resources to upsurge the speed of cross-platform app development. Its fast refresh feature reduces the time taken for testing and updation.

So, when it comes to speed, React Native is a clear winner. However, you can choose Flutter if there are fewer or no complications in your app.

Development Tools

Flutter has development tools that include a performance profiler, a network inspector, a widget inspector, etc. These tools are closely integrated with the framework and other powerful debugging tools and profiling capabilities, allowing developers to identify and resolve issues. Also, Flutter has a Hot Reload feature for rapid iteration during development and strong integration with officially integrated development environments (IDEs). These IDEs help with code completion, widget inspection, debugging, and user experience enhancement.

On the other side, React Native offers the support of Expo for rapid prototyping and to simplify the development process. It has a development environment of built-in features, including a development server, push notifications, etc.

Along with it, React Native’s Debugger is a prominent third-party tool that provides a dedicated environment for debugging React Native apps. It provides a technically advanced debugging environment using features like Reduc DevTools integration. React Native is compatible with integrated development environments (IDEs) like Visual Studio Code and facilitates extensions and plugins for these IDEs to simplify and streamline development.

Again, in this comparison, the choice is subjective to requirements and expertise. Both technologies have their limitations as well. You should choose the framework according to the project complexities, features, and expertise of your development team.

Documentation Process

Flutter follows a regimented, well-organized, comprehensive, and updated process for official documentation. It also provides detailed guides, API references, and tutorials and has a “Cookbook” section containing practical examples and solutions to common development challenges.

Whereas React Native documentation covers core concepts, it is disorganized, outdated, and clumsy. The process misses a lot of important factors that should have been covered properly.

Hence, Flutter is a better option for documentation.


Flutter uses Skia, a graphics rendering library, and the Dart language VM in a platform-specific shell. It compiles Dart’s source code by creating native code. Its code is the ultimate solution as it integrates seamlessly with both Android and iOS.

React Native uses Flux architecture introduced by Facebook that requires integration of JS bridge. This drawback automatically makes people choose Flutter over React Native when it comes to good architecture.

Learning Curve

Flutter uses Dart as a programming language, which is new and unknown to many developers. It is easy to learn if developers know JavaScript and Java, but it demands experience. Moreover, Flutter’s UI is built with widgets, which are customizable building blocks and are different from traditional mobile app development. So, developers also need to learn to work with widgets. Flutter has a less extensive community for education compared to React Native.

React Native uses JavaScript and React for programming the app. Many developers are already familiar with these technologies. They don’t have to learn a different programming language to use the React Native framework. Also, React Native has a large and active community of experts and many online resources, tutorials, and libraries available for learning and problem-solving.

In the learning curve, React Native has the upper hand over Flutter. It is more easy to learn and access, whereas Flutter has a steep learning curve due to programming language and UI design.

Ecosystem and Community

Flutter was released in 2018 by Google and is a new framework compared to React Native. It has a wide collection of plugins and widgets available in the Flutter package repository, known as “pub.dev.” Its community has many high-quality resources, including tutorials, open-source projects, and documentation.

React Native was launched by Facebook in 2015. It has a stable ecosystem and resourceful libraries, packages, and third-party integrations available through npm (Node Package Manager). Along with it, the framework has a diverse and active community of developers to provide resources for learning, like blogs, forums, and Stack Overflow discussions. The community keeps the framework updated with the latest trends and technical advancements.

React Native has a mature community and ecosystem due to its early launch, whereas Flutter’s community is not as large as React Native. So React Native is the best choice here.
