Mobile app Development

This pandemic has changed the way of availing services. People are preferring mobile apps instead of bothering themselves by going outside. Now when it comes to developing apps, the two most famous frameworks that come to mind are React Native and Flutter.

They both are equally important and useful on their terms. They both have several advantages and a few cons that should be kept in mind before choosing them. You can choose to go with a Flutter app development company or React native one to avail several benefits and valuable advice for the app development.

In this article, we will discuss the comparison between React  and Flutter which can help you to decide which one you should choose for the Mobile app development.

What is Flutter?

Flutter is a cross-platform framework. It is developed by Google in the year 2017. Its popularity constantly increases with the going number of days. It is widely getting famous among developers because it is supported by Google which itself is a strong brand. 

One thing which is appreciable about Flutter is that it is capable of creating applications for the cross-platform with a single code system. It means you can create an app for both the play store and the app store with a single code base. It eliminates the need of writing separate codes for desktop, mobile and web.

Here are some of the famous companies who have used Flutter – 

What is React Native?

It is also a famous cross-platform framework developed by Facebook. It is based on JavaScript which is used to build android and iOS apps. It also has a one code base system for apps. Its popularity is getting increase day by day as Facebook is working hard to maintain its strong position in the market. 

Here are some of the famous brands who have used React Native – 

  • Instagram
  • Uber eats
  • Walmart
  • Tesla
  • Pinterest etc.

Flutter Vs React Native 

For modern cross-platform mobile app development, Flutter and React  are the most popular frameworks. Without a doubt, the best technically sound technique to construct smooth and highly functional mobile apps is to use a native platform. Maintaining separate native codebases for each operating system, on the other hand, is time-consuming and inconvenient for developers.

As a result, every development team today uses Flutter or React  to create mobile apps. Let’s have a look at how React and Flutter are different and in which places you should use them.

Programming Language

React is a javascript based open-source framework which is used to create exceptional UIs. Most developers prefer React  over others as they find it much easy to use. Apart from this React  has gained solid popularity till now and it will gain in future as well because of its easy to learn language and tools.

When it comes to Flutter development you will get Dart programming language which is created by Google. Dart had surpassed many languages such as Java and C++. Now slightly it is getting more fame and attention from developers. According to Stack overflow, Dart is more popular than Javascript. As compared to React , it is loved more by developers.


The architecture of Flutter is layered. Often, a simple application built using this framework has a top-level root widget or a platform-specific widget. 

Basic components that engage with the platform and graphic layers come next. The animated motions that transport API calls to the application’s base were beyond the graphics layer. Overall the Architecture simplifies the creation of sophisticated apps with tiny and simple components. That’s why it is the most demanded one as compared to others.

JavaScript bridge makes it possible for React  to communicate with native languages. The JavaScript code connects with the platform and the Native API using these capabilities.

In iOS, Native development runs all programmes separately from JavaScriptCore. On the other hand, Android combines JavaScriptCore with the application. While this improves native functionality, it also expands the app’s size, which can cause technical problems or device lag.


There is a widespread belief that Flutter outperforms React . This could be because, unlike React , Flutter lacks a JavaScript bridge for interacting with native components. Due to Dart code being compiled to native code, the JavaScript bridge is eliminated. As compared to React Flutter mobile app development enhances the performance at a broad scale. 

So I can say that here Flutter is better than React. But it also depends on you what you perceive. There are chances that you may find React better than Flutter in terms of performance.

 Web Performance 

If we compare React and Flutter for website development, I would suggest React. The majority of instantaneous web pages are made with it. Javascript is one of the basic and popular front end languages which is used worldwide to create intuitive web pages. Because of this, I can say that React web performance is outstanding. 

On the other hand, Flutter required Dart which is is a programming language that isn’t widely used in website creation. It offers no substantial advantages in terms of online accessibility, pre-built infrastructure, or solutions. You can surely develop a website quickly using Flutter tools, and it will probably function better than a mobile app.

But If the site’s performance is critical, you should consider developing it with separate web-specific technology. Also, Most Flutter app developers believe that it is best for enhancing web performance.

Ease of testing 

Flutter provides a lot of support for automated testing as they have relevant tools for it. It not only has a plethora of testing options for testing programmes at all essential levels, but it also has extensive documentation for creating and releasing Android and iOS apps that help developers in imposing their new ideas. It also has its deployment procedure described formally.

For UI testing and deployment testing, React has no official support. Only a few testing frameworks are available to test React Native apps which makes it less effective than Flutter. Here developers have to depend on third-party testing tools. Without them, they cannot do perform testing.

Apart from this React does not offer any automated tools to deploy the apps on the app store and play store. It gives suggestions to developers to deploy the apps through third-party tools.

Support system 

React Native is a Facebook-backed framework that was released as open-source in 2015. React is maintained by a pool of dedicated team of Facebook who constantly works on improving React  Many facebook products are developed with the help of React and due to this, it has gained so much popularity over the years. Facebook’s extensive commitment to React makes it different from others. 

If we talk about Flutter then it is new as compared to React. If you go with Flutter app  services you get the support of Google. It’s a free and open-source SDK that allows you to build high-quality exceptional applications with a single code base.

Flutter is among the best cross-platform mobile app  platforms available thanks to the Google community as they are working hard to make it one of the best out of all. Here both have the support of the most popular organization so they are can be trusted equally. 

Which is more suitable for building Complex Apps?

The flutter framework is not suitable for more sophisticated tasks. However, companies should consider flutter as a viable option for developing MVPs. You can assume that it’s a great way to build faster prototypes and cut costs in order to experiment with your idea.

With Flutter, you should create two separate iOS and Android prototypes, and examine the results. It is necessary to study the user response and behaviour towards the app so that you can make essential changes if needed. After that, you can increase your investment and convert your simple apps to complicated ones.

If I talk about React then it can be used to create a complex app. It is more suitable than Flutter ones. It’s important to keep in mind, though, that this is only likely to work if native apps development is paired with React. It is supported by Facebook, Hence can be trusted completely without any doubt.

The whole process of developing complicated apps using React Native includes not only Javascript but also native programming expertise. 


Flutter and React Native both are good in their places. They both have a backup of the two most dominant companies that’s why they can be trusted. Now it all depends on your specific app requirements which framework you choose. It is suggested to first discuss the specific business needs and app features, then you should decide on a particular framework.

Frequently Asked Questions :

How much does flutter app development cost?

The average mobile app development time for a complicated Flutter app is six months with a cost of roughly $200 000 and over. The number of days can be exceed as it all depends on developers how much time they take to develop the app. The cost also varies as per the different regions.

What are the disadvantages of flutter?

If something has advantages then it also must have disadvantages as well. If I talk about Flutter then below mentioned are few of its drawbacks that should be keep in mind.
