Every tech-related person is engaging in the hot discussion of Flutter vs react native. Moreover, this flutter or react native topic is an important debate topic nowadays. Every developer has different views on both of these mobile app development kits. Flutter or react native are both basically a mean for developing cross-platform mobile apps. We will narrow down the topic by first discussing them separately. In addition to this, the blog will summarize the properties of flutter and react native. And, this blog compares the performance of both developing kits.

What is Flutter?

Flutter is an opesource mobile SDK that allows developers to build native-looking Android and iOS apps from a single code base. In general, one needs two different codebases for two different platforms, like in native app development for android and iOS platforms. But flutter favors one source code to compile both Android and iOS compatible mobile applications. 

Parts of a flutter:

Flutter has the following main components:

Kits for software development:

It has a range of open source tools that developers can import and re-use to make app development easy-going. They are then incorporated within the development and then compiled to formulate the useable machine codes, hence compiling Android and iOS supportive executables. 

A library of user interfaces:

Flutter uses widgets. Developers often create a complete User interface by the combination of various widgets. Every widget refers to various elements like buttons or menus. In addition, widgets also describe fonts and color schemes, and layouts like padding. Widgets are the basis of flutter for UI/UX designing.

Use of Dart in Flutter:

Flutter also includes reactive-style views for developers. Moreover, Flutter uses Dart as a counterpart for JavaScript Bridge, which is used mostly in hybrid app frameworks including React Native. So in order to prevent performance and compatibility problems caused by a platform specific compiled code. For multiple platforms, it compiles Dart ahead of time (AOT) into native code.

Various Google Assistant modules as well as the Google Home Hub user interface use flutter.  Furthermore, there are currently 50,000 Flutter applications available in the Google Play Store. And, the number is growing rapidly. Flutter is in use of Alibaba Group, eBay, Groupon. In addition, other well-known e-commerce companies use flutter to offer their web and smartphone apps a consistent look.

Benefits of using flutter

1. Efficient:

Flutter is a cross-platform application that is extremely efficient. Both Android and iOS apps will share the same base code. This adaptation helps app vendors save time and money.

2. Fast and easy

One of Flutter’s best feature is how quickly and often it responds to device compatability. Differences in devices hardware and base operating systems may be to blame for creating an uneven terrain for a mobile app vendor. These types of shifts are now being catered seamlessly by Flutter in quick time. This is successful not only in terms of bug fixing, but also contributes significantly to the rapid development of user interfaces. In a debate of flutter vs native, Flutter wins in the race of rapid yet effective app development.

3. Exceptional Performance

Flutter is the only mobile SDK that does not need the Javascript Bridge. Of all the available substitutes, the feature’s adaptation makes it the most dependable and a faithful companion. Flutter clearly stands tall in optimum hardware resources usage as compared with React Native.

4. It’s Easy to Use

Flutter is both user and developer friendly platform with a variety of features that make it seamless and natural to use. If you’re already familiar with Swift, React Native or Java, you’ll be able to tell Flutter apart quickly. Moreover, Dart is easy to implement courtesy thorough documentation and defined sets of code rules. Admit it. Developers love a brief yet concise documentation. Don’t they? Therefore, the biggest benefit of flutter lies in the Flutter vs native android domain.  

5. Uniform UI for all Platforms

If you are developer, then you can completely feel this point. It gets quite tedious to implement different UI renderers for supportive platforms, whenever you come across using a cross-platform app development framework. The only technology that actually favors one source code (including UI code) for all platforms is Flutter. This is a new revolution in the hybrid app development domain and has proven to be extremely cost effective and time saving technology. 

React Native

React Native is another widely used cross-platform app development framework. It uses only JavaScript as a programing language. Just like any typical hybrid app framework, React Native also favors one code base for all platforms. And it is a product of Facebook. Some of the world’s most popular mobile apps, such as Instagram, Facebook, and Skype use React Native technology.

React Native is an extremely popular technology nowadays. Furthermore, using the React Native Framework bridges the difference between focusing on a large market and generating revenue. Since the number of iOS users is lower than that of Android users, but iOS apps generate more profit. As a result, many industries are torn between making more money by developing iOS apps or creating user power by developing Android apps only. React Native provides best of the both worlds.

Benefits of using react Native

Its Cross-Platform Usage:

The React Native Framework was originally created for iOS development, but due to its popularity and success, Facebook decided to support the Android platform as well. As a result, REACT Native apps can be created using a single codebase for both platforms at the same time. This further increases their popularity.

It’s a World-Class Performing platform:

Initially, ‘hybrid’ or ‘mobile web’ apps were common specifically due to their rarity. When it comes to results, however, the more complicated the apps are, the more lags they encounter. React Native however, solves this problem. By allowing mechanisms to optimize app UI’s content such as images, list views and renderings, it has genuinely surpassed other cross-platform frameworks specifically in app performance.


You see what we did there? JavaScript is the most used language across the globe. Every web developer who knows JavaScript can easily learn React Native and that’s the main reason why this technology is widely popular among the developers. Not only that, React Native offers huge pool of software developers too. So if you are using this technology, rest assured that it is being backed by millions of developers. 

Flutter or React Native

Now, we know what flutter and react native is. Let’s dive into the “Difference between flutter and react Native.” React Native vs flutter performance is a huge comparison and takes part in the popularity ratio.

Programming language:

Programming language for both technologies is different. Flutter operates on Dart. Whereas, React native uses JavaScript. React Native is a more well-known system among developers. While Flutter is based on Google’s own language and is a great place to start if you are new to the app development process.

Many people seek to appoint a react native app development company. Because JavaScript is still essential in mainstream app development. Also, JavaScript is a default language for almost every browser.

Dart, on the other hand, is an expressive and safe language to begin with, which is why Flutter is so popular for developing desktop, mobile, and web applications.

Flutter vs React Native: Which Is More Popular?

Both technologies are fairly close in terms of success when it comes to cross-platform software development technology patterns. Since they are both new and have a lot of community support, they are almost similarly ruling the community.  Flutter vs react native google trends are also not very different. According to the latest trends, 20% of the mobile developers use flutter for development purposes. Whereas, 42% of mobile app developers prefer React native. India, China, Bangladesh, Japan, Jordan, and other countries favor Flutter, while Ireland, Argentina, Canada, Belarus, and other countries favor React Native.

Architectural design

It’s important to think about the technical architecture of a cross-platform mobile app development environment while making a decision. We can make an educated decision and choose the framework that is best for our project. This is if we understand the framework’s internals. 

Flux — React Native

React Native uses the JS runtime environment architecture, also known as the JavaScript bridge. At runtime, the JavaScript code compiles into native code.

Skia — Flutter

Flutter uses the Dart platform, which comes with most of the components pre-installed. As a result, this makes it larger in size and eliminates the need for a bridge to connect with native modules. Dart contains numerous frameworks, such as Material Design and Cupertino. These provide all of the necessary technologies for developing mobile apps. The Dart system makes use of the Skia C++ engine, which includes all of the required features.

The majority of native components are a part of the Flutter system. So it is not always necessary to use a bridge to connect with them. React Native, on the other hand, communicates with native modules through the JavaScript Bridge, which leads to low performance.


React Native uses node package manager for installation purposes. Developers who have knowledge of JavaScript can easily use NPM. Whereas, other developers will need to learn the concerned language. Node Package Manager is able to install the products individually and nationally. Moreover, the Home Brew package is also necessary for the installation of React native.

Flutter uses binary from GitHub for installation purposes. The Installation process of flutter is quite complicated. In the case of the macOS zip file of flutter, an extension is used.

Flutter and React Native also lack one-liner installation with native package managers for a particular OS. On the other hand, Flutter appears to require additional steps.  These are for adding the binary to PATH and downloading it from the source code. This is useful for non-JavaScript developers. Package managers help in the enabling of React Native without any use of binary.

Flutter vs react native performance comparison

When it comes to comparing the efficiency of these frameworks, Flutter is unquestionably faster than React Native at coding. When it comes to mobile app growth, the first thing that anyone looks for is app success. Without a question, React Native is a powerful language, but it is slower than Flutter.

JavaScript to machine compatible code is what makes React work. Developers must integrate additional interactions with native ones including touch events, alerts, and more to improve the efficiency of RN. However, in Flutter, there is no need to combine additional OS components, resulting in smoother and faster results.

Flutter uses Dart and includes C++. This ensures high performance and the ability to handle a variety of problems on its own. As a result, outstanding User Experience (UX) comes out.

In the comparison of Flutter vs native performance, Flutter wins the race.

UI components comparison:

Flutter surpasses React Native in this category because it uses its own UI components. As a result, this gives an app development company a lot of freedom in customizing the UI components.  The great thing is that Flutter does well with your product concept. And helps you to build an app with a single codebase. It runs and looks the same across different platforms (iOS and Android). On the other hand, React Native, uses Native elements for UI updates. But if you want to run it on multiple platforms, you’ll need to use third-party libraries.

Useability of codes:

Flutter offers its own widgets with its own high-performance rendering engine. As a result, code reusability is much simpler, faster, and more versatile.

App Development Costs:

 Whether you use Flutter or React Native, the cost of developing an app is nearly the same. The rest of the cost varies depending on the software development team’s experience.

The audience of the app:

In comparison to native apps, cross-platform apps reach a larger audience across different platforms. Moreover, it all rests on how you use the platform and its UI components to build an exceptional app to expand your app’s scope.

The audience of React Native or Flutter has not a large difference. Instead, Flutter’s audience has increased in number in the previous years. Statics for Flutter or react native 2020 has grown by about 9% as compared to 2019.
