Development of a Mobile App for both Eco-system Android or IOS is a basic necessity now as if not then you might be missing many users for your product. Development of Apps for both Ecosystems can be a tough task if your developer does not have very good familiarity with both of the ecosystems. Thanks to the Modern world we now have Cross Platform Mobile App Development Frameworks which can enable a Developer to write a code/ Business Logic once and ship to both or even multiple more eco-systems just from one codebase.

In our Previous Post, Best Programming Language for App Development we discussed the best Programming language for Mobile App Development extension in this article we'll discuss Which one is best among Flutter vs React Native, two of the most famous Cross Platform App Development Frameworks?

Flutter

Flutter is a Cross Platform App Development Framework developed by Google in 2017. Since then its popularity has been constantly increasing day by day due to its Open Source community and easy-to-use and install nature.

Flutter targets Android, IOS, macOS, Windows, Linux, and Web from a single codebase taking Dart compiler to create platform-specific hardware-optimized apps.

Traditionally a Company would require multiple developers to build Apps for Multiple platforms, due to flutter it's been reduced to One, and from just a single codebase, a developer can ship apps on all of the major platforms.

Advantages of Flutter

• Faster Development and Deployment: Thanks to the built-in features like hot-reload. The compiler compiles the code at the time of development and displays the app preview while developing only.

• Quality Documentation: One of the most important things about Open Source projects. Flutter. dev is enough for a beginner to start developing projects as a Flutter beginner.

• Feature-rich UI: Components in Flutter are completely customizable due to every component in Flutter is a Widget and Widgets get painted on the UI of the App.

Disadvantages of Flutter

• Framework age: Dart and Flutter are very young in the market, so they do not have any different use-case other than App Development.

• Dynamic Evolution: As it's pretty much young in the market, it's constantly evolving with the help of developers' support. It's the possibility that after a major update, there can be a breaking change in Flutter itself.

• Project sizes: We've already discussed that the Flutter app comes packaged with all of the app components which can easily lead to huge app sizes.

React Native

React Native is a Cross Platform App Development Framework developed by Facebook back in 2015. Since then its popularity has been increasing day by day up to the point where its GitHub Repository was ranked as the top second repository in 2018 judging from its community contributions.

React Native was initially built from the React library which is popular for its modern UI development for Web Apps. What makes it more popular is that any React Developer can easily develop React Native apps too depending upon the level of understanding of React.

If you want to learn React Native you first have to learn React to help you with that we already have curated a beautiful and interactive course React JS for beginners and Advanced React Concepts for intermediate React developers.

Advantages of using React Native

• It uses JavaScript: A Developer with React knowledge can easily start building apps with React Native without any deep knowledge. Just by using Documentation.

• Code Re-usability: Just like in React Project a Developer can reuse the components built previously with even further customization.

• It has an Active and supportive Community: As based on React itself many developers step up from just a React Developer to React Native Developer, which in turn gives the community better support by welcoming new Developers.

Disadvantages of using React Native

• Still, it is not Native: Even after developing with caution and a cross-platform app framework, still it does not make the App a native App. It still uses the JavaScript bridge to communicate with the native code.

• Does not have many Components: React Native works on customization and it already has a huge set of components but when compared with Flutter it does not have huge pre-built components.

• Abandoned Packages and Libraries: Due to huge community support the maintenance of the Libraries and Packages is not possible. This is the only reason why most of the packages are left unmaintained by the community.

Comparison between Flutter and React Native

Now, that we've got a basic introduction to what Flutter and React Native are, we can focus on what's the difference between them.

We'll differentiate between both of them based on these factors:-

• Programming Language

• Architecture

• Installation and initial configuration

• Development tools and documentation

• User Interface (UI)

• Developers Productivity

• Community Support

Programming Language

React Native uses JavaScript. To be precise React, It is a JavaScript Library that is used to develop UI for Web Apps. For Web Developers working with React Native becomes easy as they only have to write React Code which can be compiled in Platform native Code using React Native Compiler.

According to the Stack Overflow 2021 survey, JavaScript is the number 1 programming language surpassing Python, Java, and C++. So gathering JavaScript Developers and training them for React Native won't be a difficult task.

With Flutter, The Developer has to use Dart programming language which is again developed by Google. Dart has many advantages, such as Productive App Development.

Learning Dart can be frustrating just for developing apps with Flutter, luckily Dart resembles C language also known as the Mother of all Programming languages, due to the syntax of most programming languages resembling C syntax only. This makes learning Dart programming language easier for Java, C++, and other programming languages that follow OOP concepts.

Architecture

React Native compiler uses JavaScript bridge to enable the communication between JavaScript code and Native language. The communication between both sides is asynchronous which means the UI should be smooth, but that is the very reason for the chance of lagging due to the JavaScript bridge impacting the rendering speed.

In contrast, Flutter doesn't need any bridge to communicate. It has all of the components packaged with the app itself like the components and the various native code for UI. This is the very reason why Flutter apps are considered to be more stable when compared to React Native.

Installation and Initial Configuration

Installation of React Native is fairly simple, as it only requires React Native CLI installed globally alongside Nodejs. You can also use Yarn in place of Node Package Manager which comes bundled with Nodejs.

Installation of Flutter can be a tricky one. As it needs the zip file for you platform-specific should be downloaded and added to the path to be executable in your system. Installation is quite simple in React Native when compared to Flutter.

Development Tools and Documentation

When comparing React Native with Flutter, React Native is not so impressive as its documentation seems to be for only JavaScript Developers who are already into React and the React ecosystem.

Despite the low speed of Development against React Native, Many developers still prefer Flutter due to the good and rich documentation of Flutter. Perhaps the only drawback of Flutter is that you've to go on the Website for the Documentation each time. But the documentation is well structured and for anyone.

User Interface

React Native uses JavaScript Bridge to render native components to the app which allows the developer to maintain the look and feel of the native platform be it Android or IOS. The advantage of using React Native over Native App Development is that React Native has many predefined components to use to speed up the Development process. While maintaining the look and feel of the Native platform, it comes with drawbacks too. React Native Apps It's hard to replicate complex UI in React Native apps, also sometimes it can behave differently on different platforms.

Flutter has UI packed within itself only, which means developing UI that is native to the platform is easy when compared with React Native. Also, Flutter has a huge component library bundled without the need for any third-party libraries, making it consistent over all platforms.

Developers' Productivity and Community Support

React Native is an open-source framework, developers around the globe contribute to many reusable companies to speed up the app development process of a Developer, with the Hot Reload feature built-in React Native the development of the App becomes super fast with quality in mind.

Flutter on the other hand supports the Hot Reload feature and with a huge amount of pre-built components, Flutter already gets what any developer would ever need. Flutter also being an Open source framework welcomes the community to contribute to Flutter with even more amazing components with quality and stability as priorities.

Winner??

There is no such winner here. It all depends on the use case of a developer or the needs of the company. Every framework comes with its advantages or Disadvantages.

When to choose React Native??

If you've already a Web App setup and you just need to Develop an App for Android or IOS or even Desktop Apps. If you ever want to create an App that is likely to be large and deeply rooted, due to stronger and more extensive documentation. Due to its huge community, it's likely to be a very good choice for your complicated but responsive Cross Platform App.

When to choose Flutter??

If your app is UI-centered and you need a quick but clean UI prefer Flutter. With the help of Hot Reload and Dart compiler, you can easily build your MVP app within a short period with a clean UI.
