which is better flutter or react native

The developers used to face a lot of issues regarding the development of software for different platforms. It is because most of the operating systems use different frameworks. Because of this, the tools, and languages for developing the applications and software are also different. As different platforms use different native frameworks, it gets hectic for the developers.

It is because they not only have to develop the application as many times as many platforms, but they also want it to run on. But due to the difference of different frameworks, developers also have to learn different applications. As this is a very time-consuming process, a great solution is to use the cross-platform frameworks.

The cross-platform frameworks make the development of applications for the developers because they only need to design and code for one application and it can run on all different platforms and operating systems.

Being a very time-saving solution, it is attracting many developers not only because of its time-saving properties, but it also comes with a lot of benefits and features. There are a lot of cross-platform framework tools that allow developers to develop applications for different platforms however Flutter and React Native are the most popular ones.

Here we will discuss all about them and we will also have a comparison between them to know which is the better one.

How the cross-platform mobile frameworks work?

As the process of developing the same applications for different operating systems is not very efficient, the cross-platform frameworks make it efficient. It is because these platforms allow the developers to develop hybrid web applications that can work over different platforms.

Here the developers need to write code only once and that code can run on iOS, Android, and all other platforms. This also has several benefits out of which, one of the best is that it helps developers to maintain the quality of their software throughout all the operating systems.

Some benefits of using the Cross-platform frameworks:

Here are some of the best benefits of using cross-platform frameworks.

Cost-efficient development

As the applications developed here require the developers to write the code only for once, these can be very cost-effective. It is because the developers can make money several times from a single code. Additionally, the time savings will provide them more time to work on other projects.

Code can be used again and again

The code that is written on these platforms can be used again and again because most of the applications will have the same features. For example, if you are developing 2 different messaging applications, you can use the same codebase for both of them. So, code reusability is a great benefit of using these platforms.

Easy marketing

The applications developed here can be used across various operating systems. This makes it very easy to market the applications on different marketplaces.

Better user experience

When the applications are developed on these platforms, the base code remains the same so the functionalities of the applications for both platforms will be the same. However, the developers can also work to keep the user interface the same for different platforms.


This open-source development kit allows the developers to develop natively compiled applications for different operating systems. Some of the platforms that support the applications developed in Flutter are listed below.

  • Web.
  • Linux
  • Android.
  • iOS.
  • Windows.
  • Google Fuchsia.
  • Mac.

Flutter was first introduced by Google in 2015 and it went through several improvements year by year where a lot of features and different supports were included. The latest update of the Flutter came with tremendous improvements to increase the performance of the applications developed here for the iOS devices.

How Flutter works?

This is a tool that is based on 3 main components. Here we will discuss the working of all three of them.

Dart. The programming language of Flutter.

For the development of applications, Flutter uses the Dart language where it uses some of the most innovative features of Dart language for the development of applications. This is a tool that runs on all of the following platforms.

  • Windows.
  • Linux.
  • macOS.

However, in these platforms, it runs on the virtual machine that provides a run-time engine for the development of the applications on the desktop embedding project of Flutter.

As the process of debugging can get very tricky while the deployment of the application, Flutter uses the JIT comparison while the application is being developed and debugged.

It allows the developers to manage things while the application is running. One of the best things here is that the hot reload feature allows the users to change source files while the application runs.

Another great thing here is that the applications are not needed to be restarted the state where the application also remains the same while every chance of the new source file is implemented in the application. For the improved performance of the applications, Flutter uses the early build for compiling the applications on the platforms like Android and iOS.

Flutter Engine

This is a Realtime portable engine that is used for hosting the Flutter developed applications. This engine is developed using C++ so it will offer you rendering support on low-level which is supported by the Sika graphics library. This engine is a great way to use Flutter because it allows the use of the following libraries.

  • File.
  • Network.
  • Input/output.
  • Animations.
  • Graphics.

Other than these libraries, there are also some other libraries. This is a framework of libraries that can interface with platform-specific SDKs just like the ones provided from Android and iOS. This is the reason why most of the developers use the Flutter 

A great feature of the Flutter is that it provides a great structure in terms of responsiveness with an amazing layout, platform widgets, and foundation.

The Foundation library.

Just like all other development environments and languages, Flutter also has tons of libraries developed in Dart language. These libraries are used to provide the basic functionalities that are used for building a Flutter application. These libraries also help in building APIs that can communicate with the engine.

Other than this, there are widgets that are specific to design for different platforms like Android and iOS. Android and iOS are very different in terms of their graphics. The widgets sets that are available in Flutter are also different for Android and iOS as they are implemented for Google and Apple differently.

Benefits of using Flutter:

Here we will discuss some of the benefits of using Flutter.

Native features.

Some features in the application require native access because these features can only be accessed in the application by using the native coding language. Flutter makes it possible for the developers to use the following features by using the native development language.

  • Camera.
  • Geolocation.

Great performance.

When the applications are not developed in the native language and platform, there are some performance issues in the applications. However, this is not the case with Flutter. It is because the application is directly built on the machine code which helps in improving the performance of the application.

Hot reload is a great feature.

 This is a feature that is lacked by most of the application development platforms. But in Flutter, you get the functionality of a hot reload where you can make changes in the application. You can even change the source code of the application and get its functionality without the need to restart the application.

Less code is required.

With the AOT and JIT compilation support of the Dart language, it gets very easy to code the applications because you will not require JavaScript bridges for enhancing the applications.

The self-rendering engine.

A great thing about Flutter is that it facilitates the developers with the help of its self-rendering engine that utilizes Skia as the infrastructure. This makes the UI able to be virtually launched in any platform so the process of development of the application becomes very simple, fast, and convenient.

The disadvantages of Flutter:

Here are some of the disadvantages of Flutter.

Relatively new framework.

Although some features of Flutter are great, it is not a very stable and mature framework. It is because it is new in the market and it also misses some of the useful libraries that are very important for utilizing the hardware to the full extent. The missing of these features can become the bottleneck for the development of some projects.


If we compare some of the older languages that are used for the development of the mobile application, the Dart language will be very immature. The number of features in this language are also less.

When is the best case to use Flutter?

The following are the best cases to use Flutter.

  • Its hot reload feature makes it perfect if the application needs a lot of changes while it is being built.
  • Flutter is a great option for creating applications that are centered on the user interface.
  • Flutter is a great tool to create minimum viable products in no time.

The scenarios where Flutter is not a suitable option.

It is not a great option to use Flutter in the following scenarios.

  • If the application requires the 3D touch functionality, Flutter will not be the right tool.
  • Flutter is not a great tool if the application requires multiple OS interactions.
  • Flutter is not the best option for the application that requires rare native libraries.
  • If the application requires a platform-centric design, Flutter will not perform well.

Some of the most popular applications of Flutter.

The following are some of the most popular applications of Flutter.

  • Google Ads.
  • Alibaba.
  • Tencent.

React Native

This is a platform that is provided by Facebook. It used the JavaScript language for the development of the native application for the android and iOS operating systems. When the founder of Facebook focused on the need for native applications instead of creating them in HTML 5 language the concept of React Native was born and it was launched in the market in 2015.

How react-native works?

This is a platform that works on the principles of React Js. This platform runs within a background process. This process directly interprets the JavaScript that is created by the user on an end device. For the communication with the native platform, it uses serialization technique, and it relies on pure JavaScript and JSX syntax for the application development.

What are the benefits of using React Native?

The following are some of the benefits of using React Native.


As React Native uses modular architecture and native control for the development of applications, the code is created to native API without any restrictions and the performance is amazingly enhanced.

Faster updates.

When you are updating the applications built on React Native, you will take a lot less time. It is because the React Native reduces the time that is needed for carrying out the separate build process for updating applications.

Architecture is modular.

React Native has a unique architecture that is modular. It helps the developers to develop the application in the form of chunks and they can also use the chunks of previous applications with similar functionalities to reduce the development time of the application.

Easy enhancing of existing applications.

The process of enhancing the applications is very easy on React Native. It is because if you are looking to add some user interface related features, you will not need to rewrite the whole application.

Hot reloading.

While you are making modifications in the applications, you can use the hot reloading feature to see the changes on the runtime with Realtime feedback of the performance. This significantly reduces the testing time for the developers.

Live updates.

One of the best features of React Native is that it can allow the developers to make updates in the application even when the application is in usage. Users can also select this feature through their application marketplace.

The downsides of React Native

Here are some of the downsides of React Native.

  • You will need developers with expertise in the native languages.
  • Some very important components are missing in React Native.
  • React Native is not a mature platform as it is still in its best phase.

What are the best uses for React Native?

Some of the cases where it is best to use React Native are listed below.

  • A great tool for the development of applications that are needed to run cross-platform.
  • Great for the deeply rooted and expansive projects.
  • It is a tool that will be the best option when strong support is required.
  • The best option if the developers are looking to reuse the present code.
  • Provides in-depth documentation.

What will not be the right option to use React Native?

Here are some cases where using the React Native will not be a great option.

  • If Bluetooth communication is necessary for your application, then React Native is not a great option.
  • React Native is not that platform that is made for developing small applications.
  • You must not use it unless you are building a cross-platform project.

Some of the most popular applications of React Native:

The following are the most popular applications of React Native.

  • Facebook.
  • Bloomberg.
  • Walmart.

If we talk about the stats, we will get the following results.

  • According to Google Trends, Flutter is mostly used for cross-platform application development in 2020.
  • According to Statista, React Native is the most used framework in 2020.
  • According to GitHub, Flutter is more popular.

Both of these frameworks have an almost similar user base. If you step into mobile application development and use any of these platforms, you can find a great community for both platforms.

Which development language is better?

JavaScript is an older language with a huge community working on it however Dart language is introduced with a very easy syntax. If you are a filmier with JavaScript, you will find it very easy to learn and use Dart as well. However, the community of JavaScript is bigger than Dart. That is why most of the professional companies are sticking to React Native for now.

Which framework is better in terms of productivity?

Productivity means to provide great quality in less time and both the frameworks have their specific characteristics regarding productivity. Here we will discuss its form of different factors.

Hot reload.

This is a feature that is present in both of the frameworks and it works great for both of them.

Integrated development environment.

Here React Native is better in terms of productivity because many IDEs and text editors support JavaScript.

Programming languages.

For the experts, both the platforms are similar but for the new developers, Flutter will be difficult because there is not a huge community as on React Native.

Project configuration.

In terms of informative guides, Flutter is better because I will provide you with detailed informative guides whereas this is not the case with React Native.

Developers community.

If you look for the tools, the community is present for both of them. However, in terms of language, JavaScript has a bigger community.


Flutter here is better for the application where higher animations are required. It outperforms many similar platforms in this case. React on the other hand performs well for the applications where the operations that are required are intensive in CPU usage.

Which framework provides an easy learning opportunity?

If you are a developer who has a lot of experience in the field, learning to use React Native will be an easier thing because of your experience with JavaScript. Otherwise, Dart is an easier language because of its easy syntax.

Which framework will provide a better user interface and better user experience?

The applications developed on Flutter will look natural across different platforms because Flutter uses different sets of widgets for different platforms to look more native. React Native on the other hand will provide the app components which look similar to the native ones.

Continuous delivery and integration with React Native and Flutter handles

CI/CD is a special delivery technique for quick delivery of applications via automation at various development stages of apps. An essential CI/CD concept consists of continuous deployment, delivery as well as integration. It helps to resolve various issues that happen during the integration of a new code of development projects.

Continuous automation and monitoring is provided by CI/CD throughout the following.

  • Integration 
  • Application lifecycle 
  • Delivery 
  • Testing
  • Deployment 

All these practices for monitoring are known as CI/CD pipelines. They have support from the operations and development of professional collaborations which happens through the DevOps approach and SRE.

It is an important part of Flutter documentation which helps with the creation of professional apps on a large scale. To set up your CI/CD process you will have to use unofficial and external sources because it lacks official support from React Native documentation.

Publishing process of Application stores

The process of publishing apps is similar to React Native and Flutter. However, the key differences are between Google Play and the Apple store publication process. Here we have a few details to help you understand how you can manage to publish apps.

App store

  • If you are publishing on the app store you will have to manage the following requirements.
  • Pay a $99 annual fee for the development and distribution of products.
  • For the development, creation, and distribution of products, you will have to become a member of the Apple Developer Program.
  • You will get access to all high-tech and latest technologies which will allow you to engage and create unique apps.
  • Users will get all the SDKs and APIs they need for experience and engagement.
  • Before releasing applications, you can beta test them.
  • With TestFlight testing, you can get complete feedback and review in a limited time regarding the performance of your product.
  • You will have the freedom to test your product on over 30 devices.

Google Play Store

  • If you are planning to use the Google play store you will have to take care of the following.
  • Pay fee of $25 for registration of your Google Publishers Account. It is a one-time fee which means you will not have to pay every year.
  • Your account will be linked to a developer console that will enable Android app uploads, app-in purchase, subscription management, app publishing, and product page building. Users will get the facility to tweak app distribution with promotion services.
  • Apps released on Google play are faster as compared to Apple stores.
