Flutter vs React Native: Key Differences

In the dynamic landscape of mobile applications, mobile developers have many options for choosing the correct platform for mobile application development. The choice is quite easy when they have to choose from Native and Cross-platform but when it comes to choosing between two cross-platform technologies, choosing the correct platform becomes quite tough.

Flutter and React Native are two powerful contenders, each offering unique features and advantages. In this article, we will compare Flutter and React Native in different aspects which will help mobile developers to decide the right platform for their application.

Let’s get started……

What is Flutter?

Flutter, is an open-source cross-platform that allows mobile developers to build natively compiled applications for multiple platforms like mobile, web, and desktop from a single codebase only. It is developed by Google and it has received tremendous response from mobile developers. Dart language is used to develop the Flutter application, which is again developed and easy to learn as it is very similar to other programming languages like Java, and JavaScript.

Key Features of Flutter

• Multi-Platform Support: With Flutter, Mobile developers can develop Android and iOS applications using a single codebase with consistency. It also allows the developers to build Web and Cloud applications with some extra effort.
• Hot-Reload: The Hot Reload feature allows developers to view/render small changes in code instantly in the application. It is a very useful feature for rapid application development.
• Cost-Effectiveness: With Flutter developers can build Android and iOS applications using a single codebase, which helps businesses to reduce the overall cost of project development.
• Community Adoption: Flutter has a back support of Google and has a large community of developers who are constantly working and making the Flutter library rich and stable.

Limitations of Flutter

• Limited platform-specific feature: Flutter supports platform-specific features such as sensors and Bluetooth in some contexts, but it still does not give the same efficiency as native development gives.
• Learning Curve: As Flutter uses Dart which was introduced a few years back, developers with less experience with Dart may face difficulties while working with it.
• Large bundle size: Applications built with react native are always bigger in size than applications built with native platforms. Reasons behind this could be Dart runtime, Flutter engine, Framework and dependency, Assets bundling, and Ahed of time compilation.
  

What is React Native?

Another cross-platform mobile app development option that mobile developers can choose from is React Native, It is an Open-Source JavaScript framework that was developed by Facebook in 2015 and it has gained popularity among mobile developers as it also allows them to develop cross-platform mobile applications including Android and iOS. With React native developers can build cross-platform applications using a single code-base – Write once and deploy it on Android and iOS platforms.

Key Features of React Native

• Cross-Platform Support: React Native allows mobile developers to use a single code base for iOS and Android mobile applications development, Which helps businesses reduce the time and cost of the overall project.
• Combination of React and JavaScript: React native uses Java Script, a widely used and popular programming language, and React, the most popular JavaScript library used for UI(User Interface) building. Developers who are well familiar with React and Web development can take advantage of their existing skills to build mobile applications.
• Large Community: Developed and maintained by Facebook, a long presence in the mobile development landscape, React Native has a large developers community that works continuously towards the framework growth. Being a React native developer you can take advantage of large community support.
• Declarative UI(User Interface): React native platform uses a declarative UI approach, where developers have to describe the required UI, and React Native will take care of updating and rendering UI.
• Support for native modules: React native allows developers to use modules that were developed in native languages like Java, Objective C, Kotlin, etc. This helps developers to use platform-specific features and good performance experience.

Limitations of React Native

• Less performance than a native platform: In many cases/scenarios the applications developed in React Native may not gives performance as Native apps give, especially large enterprise apps, complex graphics, and animation applications.
• Debugging Tool: Debugging React Native apps is usually more challenging compared to debugging fully native apps, especially when developers are dealing with complex issues that are related to native code or third-party library integration.
• Navigation and Routing: For nested navigation hierarchy and complex user flow managing navigation and routing in React Native is quite difficult. A library like React Navigation can help but up to some context only.

Flutter vs React Native: Key Differences

Comparison Criteria	Flutter	React Native
Language	Dart programming language, developed by Google is used to build Flutter applications. Dart is an Object-oriented programming language and optionally type-supported.	JavaScript (sometimes typescript) programming language is used to build applications in React Native. React library is used for UI development.
Performance	Better performance than React Native as it uses Dart Framework, which compiles to a native platform for Android and iOS both.	Comparatively lower than Flutter as it relies on JavaScript Bridge to communicate with native components.
UI Components	Offers a rich set of UI widgets(customizable), and provides native-like (Android and iOS) performance and look.	It offers a wide range of UI components but those editor components might now look or behave exactly like native components.
Development Environment	Flutter has its own set of tools which includes Dart SDK and Flutter SDK. Developers can also use Flutter plugins with IDE such as Android Studio and VS code.	React native development requires NodeJS, NPM, and code editor such as VS code and Atom.
Hot-Reload	Flutter supports Hot Reload which allows developers to see changes rendered in the app UI without losing the app’s state.	React Native also supports Hot Reload, which allows developers to see changes instantly without rebuilding the entire app.
Community and Eco-system	Flutter has a growing ecosystem and community with support from Google. Though its rapidly growing, the community of Flutter is smaller than React Native.	React Native has a large and well-established community with detailed documentation, libraries, and third-party tools available.
Platform support	Flutter supports Android, and iOS with a single code base and Also gives support to web and desktop platforms with some extra effort.	React native initially focused on iOS and Android, but it also supports other platforms such as React Native Web and React Native Windows through community-supported projects.
Learning Curve	Flutter has a steeper learning curve for developers who are not familiar with the Dart, but its detailed documentation makes the learning process easy.	Easy to learn for the developers already familiar with JavaScript and React, web developers also can easily switch to React Native.
