Flutter Vs React Native Performance Comparison 2020


Flutter is a cross-platform mobile application that is a solution to develop beautiful UI apps. Flutter helps to make use of fast and beautiful apps. Flutter uses ways to design  Web applications with its designing views.


In flutter find similarities with HTML/CSS. Flutter is a mobile SDK that allows creating cross-platform apps to write one code and runs on both the apps on ios and as well as Android. It uses Dart language which is similar to Java which was developed by Google.



React native is Framework and it has been developed by Facebook. As it reacts but uses its native components as there building blocks instead of using Web components. React native uses a way to develop mobile apps that uses React and JavaScript.


React native is cross-platform which develops apps that support both Android, ios, Windows, blackberry and others. This React native uses JavaScript libraries to develop next-generation apps.




The key benefit of using a cross-platform mobile application development technology is the ability to use a single programming language to develop apps for both iOS and Android. Flutter makes use of dart programming language which is developed by Google in 2011 and it is rarely used by developers.

As JavaScript supports most of the object-oriented concepts it is easily understood to adopt dart syntax.

The developers mostly use JavaScript as there Core language in building apps this has helped most of the users and even React native also relays on this JavaScript. It can build mobile applications with a little bit of training with this in mind companies adopted react native as a no-brainer Javascript is a dynamically typed language and anything can be done with  JavaScript.

As react native is adopted by every framework work as it is easy to use, as dart syntax is easy to use but not popular among Web developers.JavaScript is said to be good and even some times bad but it gets adapted by the developers which are even used by the React native.




Flutter can be installed by downloading the binary for a specific platform from the GitHub page which is very easy. Installation of react native is easy both flutter and react need a black one-liner installation with native package managers for specific OS.

But flutter installation seems to require extra steps for adding the binary to the path and downloading it from the source code which might be useful for non-JavaScript developers. React native need not download any binary file from the source but just download the package manager.

React native framework can be installed with a node packaging manager that has a background that uses JavaScript. 




when choosing a cross-platform mobile app development framework. it’s essential to consider its technical architecture by knowing the internals of the framework we can make an informed decision and choose the one that is better for our project.

Flutter uses the dart framework which has most of the components inbuilt so it’s bigger and often does not require to bridge to Communicate. This needs of modules dart have used so many frameworks that uses material design and Cupertino packed inside which gives all the required technologies needed to develop mobile applications. Dart framework uses the key R C++ engine.

React native architecture heavily relies on the JavaScript runtime environment architecture also known as the  JavaScript now the JavaScript code is compiled into native code at runtime react native uses the flux architecture from Facebook.




When you are developing cross-platform mobile application support for the native component is key without this there is no support of native components. The flutter framework must have an API to access the needs of modules without any pin.

So, The Flutter framework is bundled with UI rendering, components, device API access navigation testing stateful management and loads of libraries the rich set of components remove the need to use third-party libraries.

On the other hand, the core reacts native framework provides just the UI rendering and device access API is to access most of the native module. The react native rely on the third-party and on their libraries for there components and development.




Developer productivity is key to building faster apps and in this regard. Without any weight or distraction focus on application development is very necessary. In flutter, there is a feature called hot reload which can be used to open the demo application.

However, as the complexity of the application grows developers would need to learn a lot and adopt the new flutter concepts also dart is not a  common language and there is a lack of support.


React native if the developer is skilled at  JavaScript therein it’s fairly easy to use. Those skills for cross-platform application development. After analyzing its framework IDE developers can easily use this user interface with there choice of comparison. For testing the changes in the user interface the developer is allowed to use any text editor of their choice of comparison.

This flutter has great build in there automation tools and can be deployed on any of there apps.


continuous-integration in containers delivery(CI-CD)


The practice is essential for any application to get continuous feedback and avoid releasing buggy code so react-native doesn’t have any official documentation on setting up CI-CD.  However, some articles describe the CI-CD for react native applications also find such articles on the web pretty commonly.

flutter has a  link to external sources which includes continuous integration and testing. However, flutters rich command-line interface allows us to set up CI-CD very easily and can read about them on blog post found on the web so flutter apps are easy and painless to set up on continuous integration and continuous development services by using its strong  CLI tools react-native doesn’t provide any official instructions for CI-CD  practices.



Flutter is a better option if you are going to start it from scratch as it is a very interesting and Android and ios ecosystem. React native would be a good choice if you have existing Web frontend developing skills if you have already worked with native you can go with react native.

But, Flutter is simple, easy and it also has great potential for developing an application with its ease. Creating two similar apps is better than wasting a lot of time by using this cross-platform application.
