Comparison of React Native and Flutter 2025: Which One to Choose?

As the world of mobile app development rapidly evolves, React Native and Flutter stand out as two major players.

By 2025, both React Native and Flutter continue to capture the attention of developers. Each framework simplifies cross-platform app development, but which one is more suitable for your project? Let’s explore together.

What Are React Native and Flutter?

React Native is an open-source mobile app framework developed by Facebook. It allows you to create native applications for iOS and Android using JavaScript, while also being highly effective in terms of performance. On the other hand, Flutter is a framework supported by Google that uses the Dart programming language. It aims to provide developers with a fast and aesthetic experience. Recently, I tested both frameworks on a project and found that each has its unique advantages.

While developing applications with both frameworks, I was impressed by the customizability of the user interface components. However, due to their different architectures and working styles, there are distinct differences between them. So, what are these differences? Let’s take a closer look.

Technical Details

• Development Language: React Native operates on JavaScript, whereas Flutter utilizes Dart. This can be an advantage, especially for developers who have previously worked with JavaScript.
• Performance: Flutter can offer faster performance by using its own rendering engine instead of native components. In contrast, React Native works with native components, which may lead to performance loss in some cases.
• Libraries and Packages: React Native has a vast ecosystem and offers numerous open-source libraries. Flutter, being a newer framework, may have limited library options, but it is growing rapidly.

Performance and Comparison

As of 2025, there are some interesting data regarding performance between the two frameworks. Benchmark tests conducted on high-end applications show that Flutter provides faster loading times and smoother animations.

For instance, the startup time of an application is about 1.2 seconds in React Native, while for Flutter, it is around 800 milliseconds. From a developer's experience perspective, these kinds of performance differences are quite significant.

Advantages

• React Native: It has a large developer community and resources, providing a significant advantage in problem-solving and support.
• Flutter: The speed it offers during the development process, combined with its ability to create excellent user interfaces, makes it attractive.

Disadvantages

• React Native: There can be various libraries and version incompatibilities that may lead to confusion in large applications.

Practical Use and Recommendations

So, how do these two frameworks perform in real-world applications? Recently, while developing an e-commerce application, I had the opportunity to try both React Native and Flutter. React Native facilitated the development process by quickly leveraging existing libraries, but I did encounter some performance issues. On the other hand, designing the user interface with Flutter was quite enjoyable and took less time.

I was particularly impressed by the ease of animation and transitions that Flutter offered. However, as the complexity of the application increased, learning and applying the Dart language became quite challenging. Therefore, it’s important to consider which framework you will choose when starting a project.

Conclusion

In conclusion, both React Native and Flutter offer significant options in the world of mobile app development. Deciding which one is more suitable entirely depends on your project's needs and your developer experience. Based on my experience, if you are proficient in JavaScript and want to utilize existing libraries, React Native may be a good choice. However, if you desire a more aesthetic and faster application, then Flutter might be the right path for you.
