Now that we are clear about both the frameworks individually, let’s begin with comparing them side by side, to have a better understanding of both of these frameworks.

Flutter vs. React Native: A Detailed Comparison

Both Flutter and React Native are highly popular app development frameworks and developers all across the world love creating apps using these frameworks. There is a huge demand for both React Native developers and Flutter developers in the market. However, each framework has something different from the other and hence, today we are going to compare these frameworks on the basis of:

  • Development Time
  • Development Cost
  • User Interface
  • Performance
  • Documentation Support

Let’s begin with discussing all these features in detail.

1. Development Time

The hot reloading feature in React Native facilitates developers to test UIs and change them without closing the app. One can immediately see the changes made and this saves a lot of development time. Also, as React Native is based on JavaScript, it has a rich set of modules and libraries, which makes the app development so much easier for React Native developers.

Talking about Flutter, it can sometimes be difficult to use this framework if you do not have experts working for you. Learning new concepts of Flutter can be a bit of a challenging task, which can also hamper the development time. Unlike React Native, Flutter is based on Dart, which is quite a young language as compared to JavaScript and hence, does not have that much support of IDEs and text editors. This can be a time-consuming process.

2. Development Cost

React Native development cost can be comparatively lower than the cost of creating an application using Flutter. Although both React Native and Flutter are cross-platform app development frameworks, still there are many factors that can affect the app development cost. One of the factors is the development time since the time is taken to create an app using Flutter is more than React Native, this affects the cost of app development too.

3. Performance

This is one of the most noticeable features, which is taken into consideration while choosing the right development framework. Although it is quite difficult to choose a clear winner between Flutter and React Native in this department, as both of these frameworks deliver outstanding performance.

But if we have to choose any one of them, React Native has a slight advantage here, as it is based on JavaScript whereas, Flutter based on Dart uses a streamlined process to interact with the native components. React Native can be preferred over Flutter based on cost-efficiency, faster development time, and early time-to-market.

4. User Interface

This is an important aspect of app development as users connect with your app seeing its user interface. A good user interface, easy navigation, attractive graphics play an important role in attracting and retaining users. When we talk about the user interface of an app, we can easily see the difference between these two frameworks.

React Native facilitates creating different interfaces for separate platforms by tapping into native components. Flutter follows a totally distinctive approach while developing UI elements, which is using customizable proprietary widgets. Also, React relies a lot on third-party libraries to access native modules, whereas Flutter does not have any such dependencies.

5. Documentation Support

React Native lacks good documentation support. Although it has user-friendly documentation, it lacks detailed and instant support for each issue just like Flutter. The documentation support in React Native has all the essential topics related to development like how to install and use native modules etc. but when it comes to Flutter, it has good harmony with visual studio and is fully connected with Environment (IDEs) and tools, hence it is far comprehensive. In simpler terms, React’s documentation is a bit generalized as compared to the Flutter’s one.

Flutter vs. React Native: Which One to Use when

To be honest, both React Native development services and Flutter development services are high in demand. You can choose any of them based on your project’s requirements.

Still, here are a few points which you must keep in mind while making your choice. Go for React Native if you are looking for: cost-effective mobile app solution, agile development process, effortless integration, and reuse the native components. While on the other hand, go for Flutter development if you are looking for: high-performance cross-platform apps, customizable user interface, and have enough time-to-market entry. For this, you must hire Flutter app developers having both experience and expertise to create such outstanding cross-platform mobile apps for your business.

However, if you are still unsure of which framework to go for, you can also reach out to a proficient mobile app development company as they are the best persons, who can help you in choosing the framework, which is just the right fit for your project.
