In the world of mobile app development, React Native and Flutter are two of the most popular frameworks for building high-performance, visually appealing, and user-friendly apps.

Both frameworks have gained popularity in recent years due to their ability to build apps for multiple platforms using a single codebase, making them a cost-effective and time-efficient option for app development.

However, many business owners are still left wondering which of these two frameworks is the best choice for their mobile app development needs.

In this blog post, we will be taking a deep dive into React Native vs Flutter, comparing and contrasting their key features, performance, development experience, and community support, to help you make an informed decision about which framework is the best fit for your mobile app development project.

Before comparing the key differences, let’s identify the basics of both frameworks so that it will be easier to know flutter or react native which is better.

What is Flutter?

Developed by Google in 2017, Flutter is a cross-platform software development kit (SDK) or framework for mobile app development. It uses Dart programming language (also created by Google) and is used to create apps for Android and iOS devices.

As it is cross-platform, developers can use single or multiple codebases to create apps with a native look and feel on both devices. The framework is powerful and reliable that offers various creative possibilities to build beautiful applications quickly.

The development process of Flutter is fast because of its advanced features and architectural decisions that make it suitable for building quick prototypes and MVPs as well as complex apps.  Now that we have the basics of Flutter technology, let’s identify its advantages and disadvantages. 

Pros and Cons of Flutter

Any technology has its own benefits and disadvantages, especially when it is at the beginning stage of its existence. Uncertainty about how things are going to develop or how they are going to perform later with the new product can scare off potential pioneers.

Reactive programming mode

The reactive programming model used in Flutter makes it easy to create high-performance, smooth, and responsive user interfaces.

Hot Reload

This feature makes it possible for Flutter developers to quickly and easily change the code and see the results in real-time, which can greatly speed up the development process and productivity of programmers to help with quick iterations and allows them to experiment without long delays.

Customizable widgets

Flutter comes with a rich set of customizable widgets that make it easy to create beautiful and visually appealing user interfaces. For cross-platform development, UI customization takes less time with Flutter.


Younger Community

As Flutter is a newer framework compared to some other frameworks such as React-Native, Ionic, Xamarin, etc. it has a smaller community and developers pool. This can make it harder to find help and resources when you need them

Limited Third-Party Libraries

Third-party libraries and packages play a huge role in automating software development and relieving the need to do everything from scratch. Because of the framework’s younger age, some developers may find it harder to find third-party libraries that suit their needs, which can make development more difficult.

Large binary size

Flutter has in-built widgets, and a binary size exceeds 4 MB for a bare minimum app. The binary size of the apps built using Flutter can be larger than those built using other frameworks. This may not be a big issue for many, but in some cases, it might be.

It is worth noting that Flutter is a rapidly evolving framework, and as such many of these issues may be addressed and improved in future releases.

The framework uses native components, which are similar to the components used in traditional iOS and Android development. This allows for the creation of high-performance, native-like apps that have the same look and feel as apps built using Java or Swift.

Pros and Cons of React Native

Here are some of the pros and cons of using React Native for mobile app development:

Native look and feel

React Native component corresponds 1:1 with native development components, meaning for every component in React Native, there is a corresponding native component that can be used to build the same functionality.

This combines the building blocks from the native user interface with its own JavaScript that gives a native-like appearance.

UI Focused

React Native allows building app interfaces that are fast and responsive. It has great rendering abilities and uses a component-based approach that makes it easy to create both simple and complex UI designs.

Live Reload

The live reload feature of React Native that allows you to see and work with changes in real time. You can make changes in the code while the app is loading and will be reflected in the app with an automatic reload. Flutter for React Native developers can also reload a particular area of change to save time on the compilation.


Inconsistency Across Different devices

React Native may not provide consistent performance and appearance across different devices, and developers may need to spend extra time testing and debugging to ensure compatibility, which can lead to additional costs and delay in the development process.

Limited Support for certain features

The framework has a relatively small set of libraries compared to other mobile development frameworks such as Flutter, so in case you have a specific feature you want to add to an application, it may be harder to find a library that will support it.


React Native has been around for a while, but it still lacks the level of consistency of native development, for example, iOS’s Swift and Android’s Java. It relies on a bridge to communicate with native components that cause some performance issues and lead to fragmentation across different versions of the operating systems.

This means that React Native app may not perform the same across all versions of Android and iOS and requires some extra effort to ensure compatibility.

Key Differences Between Flutter and React Native 

Flutter and React Native are both popular frameworks for building mobile apps, but there are some key differences between the two. Here’s a short comparison of react native vs flutter:

Comparison between react native vs flutter framework

Programming Language

In react native vs flutter, Flutter uses the Dart programming language developed by Google, while React Native uses JavaScript created by Facebook. Dart is a relatively new language, while JavaScript is well-established and widely used. This can make it easier to find developers with experience in JavaScript than in Dart.


In React Native vs Flutter performance, flutter’s performance is generally considered to be better than React Native’s because it uses a reactive programming model, which allows for more efficient updates to the UI.

Additionally, because Flutter apps are compiled into native code, they can run more smoothly and efficiently than React Native apps, which are run using a JavaScript bridge.

Development Experience

Some developers find Flutter’s development experience to be more pleasant than React Native’s because it provides more detailed error messages, and it has a more complete set of widgets (the building blocks of a user interface) out of the box.


Comparing Flutter vs React native popularity, Flutter has replaced native as the most used cross-platform by developers. According to a Statista survey, in 2020, React Native was used by 42% of developers, which reduced to 38% in 2021. While Flutter was used by 39% of developers in 2020, which increased to 42% in 2021. 

Community and Ecosystem

Between react native vs flutter, native has been around for a longer time than Flutter, and as a result, it has a larger and more established community. This means that there are more resources available for learning and troubleshooting, and more third-party libraries and packages that can be used to add functionality to an app.


Flutter comes with enhanced flexibility and scalability as the platform is easier to access and integrate. While React Native comes with virtual DOM and React library is an amazing framework to build scalable components. 

Overall, both frameworks, i.e., flutter and native have their own advantages and disadvantages, it comes down to your use case, the dedicated development team you hire, and your app requirements, which one you should choose.

Which is Better Flutter or React Native?

There’s no one-line answer to this question. Either of them could be better, depending upon the requirements of the project and one’s preferences.

  • Since React Native only uses necessary libraries and its architecture use JavaScript bridging, meaning it uses a bridge to communicate with native components that lead to better performance and a more polished user experience.
  • While Flutter even though is faster in performance, turns the application into a huge file size as it includes the whole framework and all of its dependencies within the app bundle. 
  • For React Native testing, developers use third-party testing frameworks such as Detox, which can add complexity to the development process, while Flutter has built-in testing frameworks.

This enables faster development and makes it easier for developers to quickly modify and make changes to the application. So choose to react native vs flutter which is better, and identify if your application falls in one of the criteria, Here are some points you can consider:

Choose Flutter, If

  • Your app doesn’t require native functionality. 
  • Need an application with user-friendly and customized UI with widgets.
  • You want to need a single codebase with multi-platform support. 
  • You aim to get code written quickly and publish your product soon.
  • You need an application that executes between 60 FPS and 120 FPS. 
  • You have less project budget and a short timeframe to complete the project.

Choose React Native, if: 

  • You need to create shared APIs out of the box. 
  • You are not considering the timeframe and budget. 
  • You need to develop simple and lightweight native apps.
  • You want to scale your existing project with cross-platform modules. 
  • You want to create an app with an asynchronous build and a highly appealing UI.
