Flutter V/S React Native

Flutter v/s React Native

Flutter and React Native by Google and Facebook respectively are the two most popular app development platforms.People are often confused which platform to choose. We will be distinguishing between these two in detail below from a developer's viewpoint.


Due to the growing popularity of mobile apps, almost every company needs mobile apps to stay competitive in the market. And what's more, companies are looking for an option to build mobile apps, especially for iOS and Android, with faster speeds and fewer resources. Although, Apple and Google have provided basic tools and technologies for creating apps. iOS app developers can create apps using Xcode and Swift, while Android developers use Android Studio and Kotlin / Java. However, this requires engineers to learn two completely different sets of techniques. As a result, companies have begun adopting cross-platform solutions over native solutions to quickly create apps for both iOS and Android using the same language.


What’s Flutter and React Native


Flutter and React Native are  open-source UI software development kit  by Google and Facebook respectively which is used to develop applications for Android, iOS, Linux, Mac, Windows etc from a single codebase.The main advantage of using cross-platform mobile application development technology is the ability to use the same programming language to develop apps for both iOS and Android.There are some key points which will help you choose one of these.


Programming Language:

Flutter uses a programming language called Dart.Dart is an open-source general-purpose programming language originally developed by Google.Dart is an Object-Oriented language  with C-style  syntax which can optionally trans compile into JavaScript. It also supports a varied range of programming features like interfaces, classes, collections, generics etc.



React Native uses a programming language called JavaScript. It is open and cross-platform and very easy to implement because it is integrated with HTML. Once you learn Javascript, it helps you develop great front-end as well as back-end softwares.


Result:Since JavaScript is a widely used  programming language, it is easy to apply it to the React native framework. Dart has a great feature set, but it is rarely used and is not well known in the developer community. Hence, React Native is better in this section .




React Native Architecture JS, also known as JavaScript Bridge, relies heavily on runtime environment architecture. The JavaScript code is compiled into local code at runtime. React local uses Flux Architecture from Facebook. Here is a detailed article about the main structure of React Native. In short, React uses the native JavaScript bridge to communicate with native modules.

Flutter uses a dart framework, most of which are built-in, so its size is large and the bridge does not need to communicate with local modules. Dart includes many frameworks such as material design and Cupertino that provide all the technologies needed to develop mobile applications. The Skia C ++ engine uses a dart framework with all protocols, compositions and channels. 


Result:The framework engine has local components and does not always need a bridge to communicate with local components. However, React uses the JavaScript bridge to communicate with local and native modules, which leads to lower performance.




React Native framework can be installed using the Node Package Manager. For developers that have a JavaScript background, installation of React Native is easy, whereas other developers would need to learn the node package manager. The node package manager can install the packages locally or globally. The developers will need to understand where exactly the binary is located. While installing React Native on macOS, we also need to have the package manager as well.


Flutter can be installed by downloading the binary for a specific platform from Github. In the case of macOS, we have to download the flutter.zip file and add it as a PATH variable. We can do this from the command line.Flutter should improve the installation method by supporting package managers like MacPorts, YUM, APT, etc so that users wouldn’t need to perform these extra steps during installation


Result:Flutter and React Native don't have a single package installation with local package managers for a specific OS, also Flutter Installation may require additional steps to add binary to the PATH and download from the source code, which is useful for non-JavaScript developers. React Native can be installed using package managers without any further installations.


UI Features and API Development:

React Native framework provides UI rendering and device access APIs. To access most native modules, you must rely on native third-party libraries. React Native relies heavily on third-party libraries.


The Flutter framework is bundled with loads of UI rendering components, device API access, navigation, testing, state management and libraries. These rich elements eliminate the need to use third-party libraries.Flutter has widgets that allows developers to easily render the UI on both iOS and Android.


Result: Flutter is easy to handle due to its inbuilt features while React Native is mostly dependent on third party libraries which makes it difficult to work with.



Both React Native and Flutter have their advantages and disadvantages, but Flutter came out on top as the winner of this match. Some professionals predict that the future of mobile app development will be flutter. Considering the comparison above, it is clear that the Flutter cross-platform has entered the mobile development race very firmly.Now its up to you which platform you are going to choose to work with.
