Flutter vs. React Native: there has been a long debate since both are powerful frameworks for mobile app development. The demand for cross-platform app development has become increasingly popular due to their powerful capabilities to develop the most stunning, feature-rich, and scalable apps with a single codebase.
In this blog, we will discuss Flutter vs. React Native and explore which one is better in 2025.
The world of mobile app development is continually evolving with the advent of emerging tools and technologies making it easier for businesses to decide which framework is perfect for their project. Developing cross-platform apps using Flutter and React Native is one of the most popular options. There are various reasons why React Native and Flutter app development for businesses is important.
And, it is important to understand their differences before choosing one of the frameworks since each has its own strengths and weaknesses. Let’s examine the popularity trends of Flutter vs React Native, along with performance benchmarks, features, and factors to consider for your business in 2025 and beyond.
What is Flutter?
Produced by Google in May 2017, Flutter is an open-source UI software development kit designed and developed. Flutter is a cross-platform app development for iOS, Android, Windows, Web, Fuchsia, Linux, macOS, and Windows.
Flutter is best known for fronted and full-stack development that leverages to design and develop app user interfaces using the single codebase for your business in 2024. It’s a software development kit (SDK) with prewritten code, extensive tools, libraries, ready-to-use, and customizable widgets to build cross-platform apps.
There are numerous benefits of Flutter app development, including cross-platform compatibility, superior performance, hot reload functionality, and many more. Many businesses today are using Flutter for their mobile app development project.
Key Features of Flutter
Here are the main features of Flutter app development:
1. Dart Programming Language
Created by Google, Flutter leverages Dart programming language to build optimized user interfaces. Dart is easy to learn and quite familiar with Java, JavaScript, or other object-oriented programming languages.
2. Hot Reload
Hot reload is one of the most important advantages of Flutter that allows developers to frequently see changes made to the code without refreshing or restarting the application. This feature significantly speeds up the development process by enabling quick iterations and debugging.
3. High Performance
Flutter applications are compiled to native ARM code, which ensures fast performance. The framework uses the Skia graphics engine to render UI components, providing smooth animations and high-quality graphics.
4. Widgets
Flutter offers several widgets that are types of building blocks to create complex interfaces using Flutter’s API. The framework offers a set of customizable widgets for various Android and iOS platforms.
5. Single Codebase
With Flutter, developers can write a single codebase that runs on multiple platforms, including iOS, Android, web, and desktop. This approach streamlines the processes and eliminates the overall development time and effort.
6. Expressive and Flexible UI
Flutter offers a comprehensive range of widgets and the ability to build custom widgets, which allows you to design and develop the most costly and flexible UIs. It also allows developers to implement complex designs and animations.
7. Strong Community and Support
Backed by Google, Flutter is the fastest-growing community, and it is rapidly growing daily. Flutter provides various tutorials, extensive documentation, and community forums, making it easier for software developers to find support and resources.
Drawbacks of Flutter
Even though Flutter is the most popular and fastest-growing application development framework, it has some challenges associated with:
1. Limited Native Features
With Flutter, you can access most device features and APIs. However, certain platform-specific functionalities require you to install additional plugins or native code integration.
2. Large App Size
Having the Flutter engine in place makes Flutter apps bigger than native apps, affecting their download size and users’ storage space.
3. Performance Optimization
No doubt, Flutter offers exceptional performance out of the box, but it may require significant time and effort when optimizing performance for complex apps with high graphics or intensive computations.
What is React Native?
Developed by Facebook, React Native is a popular cross-platform app development that allows developers to create robust and scalable apps using a single codebase. The framework leverages the power of React.js, which makes it easy to build scalable mobile applications leveraging the powerful capabilities of JavaScript syntax.
React Native is emerging as the future of hybrid app development with its thriving, active community of developers around the world. This open-source software is one of the top choices for software developers looking for flexibility and efficiency because of its modular architecture and ecosystem of third-party libraries. Furthermore, there has been a long debate between React Native vs. Kotlin since it has an extensive community and offers a few similarities to Kotlin.
Key Features of React Native
Here are the main features of React Native:
1. Hot Reloading
React Native offers a hot reloading feature that allows software developers to instantly see the changes made to the code without the need for refreshing or rebuilding the entire app.
2. Native Components
React Native offers a set of native components, including Text, View, and Image, which map directly to the platform’s native UI building blocks. It offers a consistent look and feel across multiple devices and platforms.
3. Cross-Platform Development
React Native allows you to write and deploy the same codebase across multiple channels and platforms, reducing overall development time and effort.
4. React
It uses React, a JavaScript library for developing intuitive, seamless user interfaces that let software developers build components that manage their own state.
5. JavaScript
React Native leverages JavaScript, which is the most popular programming language that makes it easier to access a large pool of talented developers.
6. Third-Party Plugins
React Native is compatible with various third-party plugins, which allows you to add or implement functionalities that may appeal to you.
7. Large Community and Ecosystem
React Native has a large and active community since this framework has been popular for years. You will get plenty of tools, resources, libraries, and support from other developers.
Drawbacks of React Native
Here are some of the cons of using React Native:
1. Platform-Specific Code
Although React Native is a cross-platform app development, you may need to add platform-specific code to implement certain features or functionalities, creating complexity in the development process.
2. Performance Bottlenecks
While React Native offers native-like performance, it may experience performance bottlenecks with complex or computation-intensive tasks than fully native apps.
3. Limited Access to Native APIs
There is a possibility that React Native does not support all native APIs, requiring developers to write native modules or rely on third-party libraries to support certain native features.
