React js vs flutter: Which Should You Choose?

React JS vs. Flutter: Which Should You Choose?

Mobile app creation is a fast-increasing sector, particularly in light of the demand for specific lifestyle and communication apps during COVID-19. Businesses hire react js developers to make applications and give good results. However, developing apps for both iOS and Android necessitates two separate teams and skill sets. React js vs flutter has always been in talks when it comes to the development of mobile applications.

Today, we’ll guide you through some of the most popular apps created with each platform and have a comparison of React js vs flutter on the basis of their functionality and histories. By the end of this blog, you’ll have a basic knowledge of React js vs flutter.

What exactly is Flutter?

Flutter is an open-source, cross-platform reactive mobile application framework that employs the programming language. Moreover many misunderstand flutter as one of the javascript frameworks but in fact, flutter is a whole software development kit.

Furthermore, Flutter uses Dart language as its programming language. Flutter is moreover used to make both front-end and back-end applications.

Features of Flutter

You are now aware that Flutter is a well-known mobile app development framework. Let us go to the top features or benefits of Flutter:

  • Open-source Platform – Flutter is an open-source front-end development platform. It enables developers to turn their ideas into visually appealing app developments.
  • Hot Reload – Flutter supports hot reloading, which means that the most recent changes in the code are immediately available/visible. As a result, developers do not need to reload the code to see the most recent changes.
  • Rich Widgets – Flutter includes rich widgets for structural and stylistic aspects, among other things. As a result, developers may design an appealing and expressive user interface based on the client’s business model.
  • Community Support – Flutter has a large developer community to support.
  • Single Code Base – Flutter provides a single code base for cross-platform app development, so developers don’t have to code differently for iOS or Android apps.
  • Google Firebase Support – Flutter also supports Google Firebase, which is useful for backend development.
  • Rapid App Development – With Flutter, developers can create sophisticated apps quickly and effortlessly.
  • Expressive Interfaces – With Flutter, developers can easily and quickly create expressive interfaces.
  • Faster Debug – Flutter includes excellent capabilities that enable developers to work more quickly on development and debugging.
  • Simple Learning Curve – Because Flutter is a straightforward framework to learn, it is accessible to developers of all backgrounds.

What exactly is React JS?

React js is a free and open-source JavaScript toolkit that web developers use to create user interfaces that use UI components. Moreover, React js is frequently used to create single-page web applications.

On the other hand, React is just concerned with handling the state and rendering it to the DOM.

As a result, React applications typically necessitate a specific client-side capability as well as supplementary libraries for routing.

Features of React JS

ReactJS is a prominent front-end development library frequently utilized by developers for robust development. Take a peek at the top features that ReactJS provides to developers:

  • Virtual DOM – React provides virtual DOM, which helps to speed up the development process while also providing code flexibility.
  • JavaScript XML or JSX – XML creates a syntax similar to HTML for creating React components. The building blocks are really simple to write in JSX.
  • React Native – This functionality converts React code such that it gets used on iOS or Android systems.
  • Data Binding in One Direction – It regulates data flow, making it more adaptable and effective. As a result, it forces developers to use the callback feature to edit components rather than altering them directly.
  • Declarative UI – Declarative UI makes React code more readable and makes bug fixes easier.
  • Component-Based Architecture – React JS comprises numerous components, each with its own logic written in JS. As a result, developers can convey data around the program without affecting the DOM.
  • Increases Developer Productivity – Because of its fantastic capabilities such as component reusing, ReactJS helps to increase developer productivity.
  • Developer Toolbox – It provides an excellent toolkit for developers to use in creating powerful solutions.

React js vs flutter: Which Is Better?

Although both ReactJS and Flutter are fantastic for UI development and design, it is important to consider the requirements and usage. Both React and Flutter share many commonalities, such as the ability to build cross-platform apps with a single codebase, hot reloading, amazing UI, awesome tooling, and React functionalities. They do, however, developers always have a discussion over React js vs flutter and which is better.

There are three major factors to consider while discussing React js vs flutter. These principles will help you comprehend both better and make an informed decision.

1. Programming Language

The developer can create a single code for iOS and Android devices by utilizing the cross-platform application technology ReactJS.

ReactJS is a JavaScript package that allows you to create user interfaces in JavaScript. JavaScript is a dynamically typed programming language that allows developers to achieve a wide range of things, but it is also incredibly cumbersome. Because JavaScript is a popular programming language, mastering it does not need much time or effort. This makes it simple for developers to learn and implement ReactJS.

Flutter, on the other hand, is Google’s Dart programming language, which got launched in 2011. Dart is a hybrid of JavaScript and Java. If you have prior experience with JS, C#, or other object-oriented programming languages, the language will be easier to learn.

Because of its expressiveness, Flutter has quickly become a popular innovation among cross-platform mobile app developers. Because JavaScript has been around for so long and is widely used by web developers, ReactJS is straightforward to build.

2. Architectural Technology

When comparing React js vs flutter as two technologies, it is critical to understand their technological architecture. ReactJS makes use of JavaScript bridge, a runtime environment that enables communication with native modules.

Using Facebook’s Flux technology, ReactJS converts JS code into native code during runtime. The requirement to integrate native modules with JavaScript code during runtime can cause the app to slow down in some cases. However, framework performance is usually satisfactory.

The framework’s performance, on the other hand, is usually satisfactory. In fact, Flutter already has the majority of the necessary components. As a result, you don’t require a bridge because Flutter already makes use of frameworks such as Material Design and Cupertino in addition to the Skia C++ engine.

Apps built using Flutter are more stable than ReactJS since Flutter provides the essential channels and protocols. The availability of numerous capabilities usually eliminates the need for developers to use other technologies.

3. Development of UI Components and APIs

Your app will not feel native without this support. The framework must allow easy access to native modules, as access to native modules is critical when designing cross-platform programs.

ReactJS, in addition to ReactJS and React Native, can construct a Native environment using JS Bridge. However, ReactJS requires third-party libraries to access native modules, resulting in unpredictable app behavior.

With Flutter, you can easily render UI components while navigating, accessing device APIs, maintaining state, and leveraging multiple libraries – eliminating the requirement for third-party libraries. It includes widgets for Material Design and Cupertino, allowing developers to easily render UI. As a result, Flutter is rich in developer APIs and UI components. ReactJS, on the other hand, is heavily reliant on third-party libraries.


However, most software development companies are typically at a loss as to which framework or technology to use for the best mobile app development results. Flutter and ReactJS are now the most popular frameworks and libraries in the mobile app development space.

Both Flutter and React are robust when used effectively for the demands of a project. Hence React js vs flutter will always be in talks for software development companies.
