What is Flutter and React native?

Flutter- Flutter is a mobile app SDK for construction high-fidelity, high-performance, apps for Android and, iOS from an on its own codebase.

React Native- React native is an open source outline released on GitHub that covered the method for uniting both the Android and iOS platform’s natural APIs.

Programming Language

React Native – JavaScript

React Native customs JavaScript to construct cross-platform apps. JavaScript is a very standard language in the network community at the instant. It is usually used with React and other general JavaScript outlines.

Flutter – Dart

Flutter uses Dart programming language which was presented by Google in 2011 and is hardly used by designers. Dart syntax is easy to know for JavaScript or Java developers as it supports most of the object-oriented models.

Technical Architecture

React Native: React Native’s application planning is identified as Flux. Facebook uses Flux to construct client-side network applications. Every outline typically surveys the MVC framework. The unidirectional data flow is the key concept of Flux.

Flutter: A Dart app structural design collection with uni-directional information flow stimulated by RefluxJS and Facebook’s Flux. Flutter-flux implements a uni-directional data flow design included of Movements, Stocks, and Store Viewers.


React Native: React Native writing your necessity a bond to call Swift or Windows or Android & Mac APIs, with Flutter it’s dart so you don’t want that all possibilities would be native, this also resolves the problem with the JS Ecosystem divided between various versions like CommonJS, AMD.

Flutter: Comparing both Facebooks React Native vs Google’s Flutter on the base of their app performance, it is the Flutter takings the top over its contestant.

User Interface

React Native: React Native App Development needs to use third-party collections meanwhile React Native does not have a UI mechanisms collection of its individual. We used mechanisms such as NativeBase, which is an open-source UI mechanisms collection created by geekyants.

Flutter: Layout widgets are presently a portion of the application, fresh widgets can be involved and current ones can be changed to give them an alternative texture and aspect, the tendency has now altered and the UIs have developed more user-friendly, cool to use, upsurge user visit, and win awards.

Community Support

React Native: React Native released as open source on GitHub and is the utmost popular outline on Stack Overflow it is supported by a vast public with 68k stars on GitHub, 14.5k customer subedit, ~9000 user Discord conversation and robust support on Stack Overflow that’s why it has added third-party collections.

Flutter: The Flutter team can be established for provision in a ~4.5k user subedit, ~30k stars on GitHub, ~740 customers on Google Group and on Stack Overflow.

Testing Support

React Native: React Native is a JavaScript outline and here are a few unit level testing structures offered in JavaScript. The implements like Jest can be used for photo testing.

Flutter: Flutter provides a rich set of challenging features to test apps at part, widget and integration level.

Development Time

React native has various third-party books, such as Carousel, Calendar, and Modal Also It has ready-to-use mechanisms, which develops the speed of cross-platform app development.  In Flutter, we need to enhance distinct files for both iOS and Android podium. In each of these records, we want to improve code that resembles the instructions of the platform.


React Native and Flutter together have their pros and cons, but Flutter came out as the winner in this competition. Some of the business specialists have predicted that Flutter is the future of mobile app development.
