The above image indicates that the popularity of both frameworks is increasing over time. However, Flutter is currently more popular as compared to React Native.

Flutter vs React Native Popularity Survey by Stack Overflow

Stack Overflow surveys to know the popularity of various frameworks, tools, and technologies every year. In the year 2020, Stack Overflow conducted this survey on 65,000 developers.

According to the same poll, the popularity of Flutter is more than React Native in terms of the most loved framework with 68.8% of votes, while React Native has got 57.9% of votes.

Developers who aren’t familiar with any cross-platform frameworks showed more interest in learning React Native than Flutter.

Flutter vs React Native Stack Overflow Survey

As per the survey, around 14% of developers showed interest in learning React Native. On the other hand, only 10.75% of developers would love to learn Flutter for developing apps.

According to Statista, around 42% of developers worldwide use Flutter, and 38% of developers prefer React Native for developing cross-platform apps.

Programming Language


Flutter uses Dart programming language, which was developed in 2011. Dart is based on object-oriented concepts that can be tricky to understand. But it has straightforward syntax.

Any developer familiar with C/C++, Java, and JavaScript languages can start their journey easily. But only a few developers out there have learned it, so when it comes to comparing the ease of use, Flutter loses the round.

React Native

React Native heavily depends on JavaScript to develop apps that run on multiple platforms.

The huge developer community, from website designers to software engineers, widely used javascript due to its dynamic coding. It is one of the primary languages among different browsers.

When we ask developers if Flutter will replace React Native, they usually answer no, due to its pre-built modules and easy-to-work-on framework.

Technical Architecture


The framework uses the Skia engine, dart language, and 2D graphics rendering library that comprises various protocols, compositions, and channels. It compiles dart’s source code while creating native code.

Dart’s code is simple and offers a speedy solution. Developers don’t need programming bridges for any customization; it seamlessly integrates with iOS or Android.

In this point of Flutter vs. React Native comparison, Flutter is the clear winner due to the elegance of its design.

React Native

React Native uses Flux architecture. It required a JavaScript bridge to run the codes. Due to this, the app rendering time is inherently slower than Dart, which is a drawback of Flux in comparing Flutter and React Native architectures.

Installation and Configuration


Installation of Flutter is quite complex and time-consuming. Flutter does not use programming bridges, so developers have to download the full binary for the particular platform from its GitHub repository.

You will also need a .zip file for macOS installation to use a PATH variable. It has an in-depth installation guide, so developers without knowledge of dart can also install it. But the installation process is slow and requires more steps to follow.

React Native

When it comes to installation, React Native is easy. Using the node package manager (NPM) and having a good command of JavaScript will make installation seamless.

Both frameworks need a one-line installation and native package manager for OS, so no framework is perfect at this point. Flutter calls for one extra step, so in comparison, React Native wins every time.

One downside, it does not provide an installation guide in detail.



Flutter offers the best performance and wins the race as it runs faster than its rival. It doesn’t have a programming bridge to slow down and saves development time.

Giving proof of quick running performance, Flutter has set its animation standard at 60 FPS to operate efficiently. Though it has a huge program with many native components, consider this factor before proceeding.

This framework provides you with numerous documentation on how to reduce file size.

React Native

React Native is a powerful framework though it doesn’t deliver performance close to Flutter. Elegance and strength of its design is the key factor developers looking to develop in Flutter.

In React Native, it requires JS bridge to interact with native modules and also the frames dropped in more than Flutter.

Though it doesn’t make React Native apps slow, developers need to work on enhancing the performance.

Need Help to Build an App Using Flutter?

Building an app with Flutter is easier than you think, especially when you have the right team in your corner. Let us be that team!

UI and Development API


Flutter framework relies mainly on its own customized UI development toolkits. Using its own widgets, it’s fully customized and a key advantage over React Native.

These widgets are fully compatible with Apple’s Cupertino and Google’s Material Design. Moreover, it is also natively compatible with Google.

Third-party apps or custom components are not required. So in the race of Flutter vs. React Native, compatibility associated with Google is the biggest reason why Flutter wins the race.

React Native

React Native needs a third-party or custom component. To make the component work, you need to use patches in your code. However, React’s Javascript development language has its own set of benefits. So in comparison, Flutter definitely wins.

Development Time


As we know, Flutter framework uses Dart language which is not easily understood by developers and needs time to assemble it. People love the hot reload feature of it.

Also the framework lacks the support of several text editors and IDEs which adds additional time to the development process.

React Native

React Native has JavaScript which makes development easy. It is simple and accessible to web developers and web designers more.

Developers can use any IDE or text editor of their choice. When it comes to development speed, React Native is superior to all.

Code Reusability


Code reusability is a huge topic. Flutter’s codebase is reusable than React Native. Developers can define a new logic and reuse the code for another purpose. Even Flutter allows you to change a single line in your codebase.

Google has made Flutter interface simple, and highly intuitive which contributes to easy reusability.

React Native

React Native allows you to write code once and apply it to every platform. But compatibility is not always guaranteed on any type of mobile app platform.

It requires developers to load different sets of components that operate. These alterations need time and cost. So while comparing, Flutter stays ahead.

Community Support

For building any mobile application, the support of a community helps to resolve any issues quickly & effectively.


The Flutter community is expanding. Currently, there are only 1120+ Flutter contributors on GitHub for any professional help.

As of now, Flutter has got 149k stars on GitHub and 24.4k live projects forked by the community. Here, anyone can use these projects for development purposes.

React Native

React Native is an open-source library. At this moment, there are 2430+ professional contributors of React Native on GitHub and 107k stars.

Besides this, 22.8k forks of the live projects which any developer can use for the project. Due to this, various developers prefer to go with this framework.

Testing & Deployment

Testing is yet another factor that developers consider when choosing a cross-platform framework. Ensuring that your code runs smoothly with less time and effort is the main objective of any development.


Flutter offers better testing of apps than React Native. It provides top-notch support to developers to conduct automatic testing of apps as it relies on Dart. It possesses various features to test apps at the unit, widget, and integration levels.

Besides this, it also provides a unique feature for developers to create widget tests to test the user interface and leverage unit testing.

React Native

React Native doesn’t offer any support for unit and integration-level testing. Moreover, there are only some specific tools for unit-level testing of React Native apps.

Hence, developers have to utilize various third-party tools available in the market, such as Appium, Detox, and Jest, for conducting different kinds of testing.
