Flutter vs React Native: A Brief Comparing

You are thinking about creating your own mobile app if you read this. This is a good decision, considering its revenue overall will reach $613 billion by 2025

When choosing a suitable app development framework, several questions arise, and the main one is about the software frameworks. As for 2022, React Native and Flutter got top positions among cross-platform app development frameworks. 

This article will focus on what these frameworks stand for, their pros and cons, and how to choose the proper one for your project. Let’s dive into the details.

React Native vs. Flutter: Which is Better for Your Project?

The difficulty of choosing between these two frameworks is that they are both cross-platform and have their special features. You could also read about some other JavaScript solutions such as NativeScript, Angular, or TypeScript that expand JavaScript possibilities. Today we will talk about two software frameworks that are at the top of popularity and cause the most discussion.

To finally make a choice, you should pay attention to their popularity, simplicity, functionality, and other criteria that we will analyze in today’s article. Keep reading.

What is Flutter? 

Flutter is an open-source framework from Google that provides a straightforward way to build any hybrid or cross-platform application. Since it’s based on the object-oriented Dart language, it’s easy to learn and use, especially for developers who are familiar with Java and C# architecture. 

Flutter Pros and Cons

Our research indicates the main advantages and drawbacks of Flutter, which should be taken into consideration when choosing. Let’s start with Flutter’s pros

Unified Codebase 

With Flutter, developers can write code for both Android and iOS. Since the same design is used, you can get an identical app for users of different systems. In addition, ready-made widgets will make the development process faster and easier. 

Community Support

With the backing of thousands of developers, you can find answers to your questions and solve code issues. Also, Google provides Flutter with updates and bug fixes up-to-date, so your app will stay secure and protected.

User-friendly UI

“The devil is in the details”, that’s why Flutter is focused on a better UI to help you attract more users. According to it, you are able to create an intuitive interface, customize built-in widgets or create your own. 

As for the cons, there are the following:

Lack of libraries 

Third-party tools allow you to save time on creating elements from scratch. So far, The Flutter base is not so developed, since the framework itself is quite new. Open-source libraries are evolving, and over time developers will be able to use rising numbers of ready-made and tested solutions. 

Large Apps Size

Developers need to create an app that will occupy the minimum possible amount of memory. To reduce the app’s size, you have to remove certain features and make elements or widgets simpler. For examples, Java app size is around 539 KB, Kotlin is about 550 KB and Flutter exceeds 7.5 MB according to Medium research

Need To Learn Dart

According to the review, Dart is not that popular programming language with a small community. Still, if the developer works with Flutter, it involves writing in Dart. Due to the limited number of resources, it’s increasingly difficult to develop apps with Flutter. 

When To Use Flutter? 

The uniqueness of the project also determines the framework that is optimal for its creation. Flutter will be relevant if your future app involves that you:

  • Have a limited project budget and a constrained time for development
  • Want to provide a better app performance 
  • Need a complex user interface 

What Is React Native?

React Native is a cross-platform solution for mobile apps development. One of its features is that developers use the same UI building blocks with JavaScript and React instead of building in Kotlin or Swift. 

React Native Pros and Cons

To learn more about whether React Native is suitable for your project, we will dive into the main advantages and disadvantages. Let’s start with its pros.

Easy to Code

This framework doesn’t require CSS or HTML knowledge, developers only use React Native and JavaScript for creating apps. Due to this, the average development time is also reduced. 

Android & iOS Support

The written code will be natively displayed on both platforms, so there is no need to spend additional resources to create separate apps. In development, it is important when you modify the code’s elements, they also change across Android and iOS platforms. 

Better User Experience

According to the statistics, every dollar a company spends on improved UX gives them back $100. With React Native, you are able to provide high-grade page downloading time and smooth interaction. 

Now let’s pay attention to the cons

Issues With Updating 

After some research, we found that upgrading React Native is a challenging task that requires some extra effort. Since it’s a multi-step process, developers have to be precious and not miss even one stage. Instead, it can lead to debug issues, and as a result — even more time to fix bugs. 

Lower Performance

Compared to native apps, the performance is still quite slower. Also, if you are more about complicated interfaces, React Native is not the proper choice and you better select the native development. 

Large Apps Size For Android

Unlike other Android apps, written with React Native have a larger size, up to 7 MB. The reason for this is that Android natively doesn’t have the possibility to run JS code. Therefore, there is a need to add a ReactJS library to the app that supports the written JavaScript code. It’s quite inconvenient and requires additional MB. 

When To Use React Native?

Our research indicates that there are two main cases to choose React Native when it comes to developing an app, so you:

  • Want a cross-platforming app with better performance 
  • Already have a desktop version or a website
  • Need to hire a team for fast mobile developing

As for React Native, it provides a large community of developers, which makes the developing process easier. On the other hand, Flutter has more ready-made solutions, for example, on GitHub


  • Is React Native better than Flutter?

    Both competitors have their advantages and disadvantages, and the choice will depend on the specifics of your project. Pay attention to performance, how large your program will be and how many resources are needed.

  • Will Flutter replace React Native?

    As both teams are constantly improving Flutter and React Native, and their communities are growing, we cannot talk about a complete replacement. As we can see from the statistics, the popularity of this framework is increasing, but React Native holds no less high position in the ranking.

  • Is Flutter faster than React Native?

    Apps based on Flutter run faster because it doesn’t have any JavaScript bridges and compile into native code for both Android and iOS. And the animation standart 60 FPS provides high and faster performance.

  • Which has more demand, Flutter or React Native?

    To answer this tricky question, let’s look at the statistics. Among professional developers who participated in the survey, 13.62% chose React Native, and 12.56% voted for Flutter. Both alternatives go hand in hand, and their differences, for example, the environment configuration, determine whether it suits your project.
