What is the major difference between Flutter and React Native?

Please explain breifly

Flutter is an open-source mobile application framework that works on a completely different programming language called Dart, While React Native lets you build mobile apps using only JavaScript.Unlike React Native with Javascript bridge.


Your answer is right but I like to add some points :grin:


What is Flutter?

Flutter is a UI toolkit for creating fast, beautiful, natively compiled applications for mobile, web, and desktop. It builds the app with one programing language and a single codebase. It is free and open-source. It was initially developed by Google in May 2017 and now manages by an ECMA standard. Flutter is a mobile framework that uses Dart programming language for creating an app. The dart programming shares several same features as other programming languages, such as Kotlin and Swift, and can be trans-compiled into JavaScript code.

Flutter is mainly optimized for 2D mobile apps that can run on both Android and iOS platforms. We can also use it to build full-featured apps, including camera, storage, geolocation, network, third-party SDKs, and more.

Features of Flutter

Flutter gives easy and simple methods to start building beautiful mobile and desktop apps with a rich set of material design and widgets. Some of the essential features of Flutter are given below:

Open-Source: Flutter is a free and open-source framework for building mobile apps.

Cross-platform development: This feature allows Flutter to write the code once, maintain, and can run on different platforms. It saves the time, effort, and money of the developers.

Hot Reload: Whenever the developer makes changes in the code, then these changes can be seen instantaneously with Hot Reload. It means the changes immediately visible in the app itself. It is a very handy feature, which allows the developer to fix the bugs instantly.

Accessible Native Features: This feature allows the app development process easy and delightful through Flutter’s native code, third-party integration, and platform APIs. Thus, we can easily access the SDKs on both platforms.

Minimal code: Flutter app is developed by Dart programming language, which uses JIT and AOT compilation to improve the overall start-up time, functioning and accelerates the performance. JIT enhances the development system and refreshes the UI without putting extra effort into building a new one.

Widgets: The Flutter framework offers widgets, which are capable of developing customizable specific designs. Most importantly, Flutter has two sets of widgets: Material Design and Cupertino widgets that help to provide a glitch-free experience on all platforms.

Let us understand the essential differences between Flutter and React Native with the following comparison chart.

What is React Native?

React Native is an open-source JavaScript framework developed by Facebook. It is used for developing a real, native mobile application for both Android and iOS platforms. It is a JavaScript framework that builds upon the React library to create mobile apps with a single codebase. It uses native components rather than using web components as building blocks. It has a cross-platform feature, which allows you to write code once and can run on any platform. It saves your development time as it will enable you to build apps by using a single language JavaScript for both Android and iOS platforms.

Features of React Native

React Native provides many advantages for building mobile applications. Some of the essential features of React Native are given below:

Open-Source: React Native is free and open-source. It means anyone can use it easily.

Cross-Platform: It offers the facility to “Write once and run everywhere.” It is used to create apps for Android, iOS, and Windows platforms.

UI Focussed: React Native is mainly focused on UI. It makes the app interface highly responsive.

Performance: The code written in React Native is compiled into native code, which enables it for all operating systems to provide closer native appearance and functions in the same way on all platforms.

Hot Reloading: Making a few changes in your app’s code immediately visible during development. If the business logic is changed, its reflection is live reloaded on screen.

Support For Third-Party Libraries: React Native support many third-party libraries to make an app interactive.

Faster Development: React Native allows you to reuse the code which is already written. This feature helps you to develop apps fast. It uses a common language to build an app for Android, iOS, and Windows platforms, which gives speedier app deployment, delivery, and quicker time-to-market.
