Everyone accesses the internet with a mobile phone. They install software and run it to fulfil their digital needs. But how are these apps created? The process to create a mobile application involves a lot of technologies. Here we will discuss Flutter vs React Native to find out the best cross-platform framework to use in 2023 for your business. 

Flutter vs React Native: What are they?


Google developed Flutter in 2017. Since then Flutter’s popularity grew steadily over the years. Flutter is a cross-platform framework for developing native android and iOS apps using a single codebase.

Flutter uses the Dart programming language which was also developed by Google. One of the key features of Flutter is its fast development cycle, which allows Flutter developers to quickly make changes and see the results in real time. Flutter also includes a rich set of customizable widgets and tools for building beautiful and responsive user interfaces.

React Native

React Native is a UI framework to develop mobile apps for Android and iOS using JavaScript.

Like Flutter, it allows React Native developers to build a single codebase that can be compiled and run on multiple platforms. Facebook developed React Native which is based on the popular React JavaScript library for building user interfaces. It allows developers to use familiar tools and concepts from the web development world, such as the React component model, to build high-quality, performant mobile apps.

Flutter vs React Native Performance: Which one is Better?

Developers utilise Flutter vs React Native performance to build high-performance mobile apps. But it is difficult to compare the Flutter vs React Native performance. Let’s see why is it so.

The performance of a mobile app depends on many factors: the device it is running on, the complexity, how it is coded, etc.

Flutter has one advantage due to its rendering engine. It has a high-performance 2D rendering engine called Skia, to draw the user interface(UI) using different widgets. Flutter uses Skia and the Dart programming language to draw the app’s widgets and manage its content internally. 

When a Flutter app runs on a device, it requests a window from the operating system and takes control of rendering and displaying content within that window using Skia and Dart. It allows Flutter to create high-performance mobile apps. 

React Native apps have advantages because of platform-specific features and integration. Developers take advantage of platform-specific features and APIs by using native components to develop React Native apps. Easing the building of apps that emulate platform-specific designs.

It is difficult to determine a clear winner in terms of Fluttervs vs React Native performance. 

  1. Both frameworks are open-source and well-maintained by Google and Facebook.
  2. Both offer hot reloading for efficient development. 
  3. Both offer a native app experience. But Flutter’s use of Dart code that compiles directly to C may provide a slight advantage in performance over React Native’s reliance on JavaScript bridges. 

However, React Native has implemented new architecture, including JavaScript Interface and TurboModules to improve performance. 

At last, Flutter vs React Native performances are continually evolving with the support of their respective developer communities.

Developers often consider Flutter and React Native for building native mobile applications. Both frameworks have their own unique set of features and limitations. A head-to-head comparison between Flutter vs React Native can help us understand the strengths and weaknesses of each framework and determine which one is the best fit for your project.

Flutter vs React Native: Installation


You must download the binaries for the particular OS you select from GitHub in order to install Flutter. There is even one more step involved in installing Flutter for macOS: downloading and adding a PATH variable for an additional.zip file. This is one of the main distinctions between Flutter vs React Native, which makes installation slower and more difficult.

React Native

React Native is simple to install. With basic JavaScript knowledge, developers can install React Native via the npm (node package manager). 

How Programming Language Differs between Flutter vs React Native?

Dart and JavaScript are both high-level, object-oriented programming languages, but there are some key differences between them:

  • Syntax: Dart and JavaScript have similar syntax with few subtle differences, such as how variables are declared and how classes are defined.
  • Typing: Dart is a statically typed language meaning variables have a fixed type that must be specified when they are declared. JavaScript is a dynamically typed language, which means that the type of a variable can change at runtime.
  • Execution: JavaScript is typically run in a web browser, while Dart can be run both in a browser and on the server-side using a standalone Dart virtual machine.
  • Ecosystem: JavaScript has a much larger ecosystem and developer community, with a wide range of libraries and frameworks available. Dart has a smaller ecosystem, but it is growing rapidly.

Flutter vs React Native: Differences between Architecture


The architecture of Flutter consists of the Flutter engine, the Flutter framework, and the Flutter application.

The Flutter engine is responsible for rendering the Flutter application to the screen and providing low-level APIs for accessing platform-specific functionality. 

The Flutter framework is a layer on top of the Flutter engine that provides a set of reusable UI components and high-level APIs for building applications. 

The Flutter application is the actual app that is built using the Flutter framework and runs on the Flutter engine.

React Native

The architecture of React Native has The JavaScript runtime, The React Native library and the React Native application.

In the React Native architecture, the JavaScript runtime serves as the bridge between the React Native application and the native platform. The React Native library provides a set of native UI components that can be used to build the user interface of the app, and the React Native application is the actual app that is built using these components.

Flutter vs React Native Future

Flutter vs React Native Future looks bright with continued growth and popularity expected in the coming years. Both are top-notch cross-platform mobile app development frameworks and are rapidly gaining traction in the industry.

According to a recent survey, Flutter has been adopted by 45% of developers for their mobile app development projects and is expected to grow to over 70% in the next 2 years. With its fast development cycles and visually-rich UI, Flutter is a popular choice for businesses for building high-performance mobile apps.

React Native has been widely adopted since its launch in 2015, with over 95% of developers reporting that they are satisfied with the framework. A recent study found that React Native-based apps have a retention rate that is 20% higher than other cross-platform mobile app development frameworks.

Flutter vs React Native: Which Framework to choose in 2023?

This article analyzes the factors that contribute to the rising popularity of the two new cross-platform application development frameworks, Flutter and React Native. The problem of writing separate code for native platforms like Android and iOS is resolved with Flutter and Native. The same code may now be used to construct applications for all platforms.

Additionally, the optimal framework for you will rely on your skills, needs, and the commercial goals of your project.
