Flutter vs. React Native: Choosing the Right Cross-Platform Framework

React Native vs Flutter

In the world of mobile app development, creating a seamless and efficient user experience across different platforms has always been a challenge. Traditionally, developers had to build separate applications for iOS and Android, leading to duplicated effort and increased development time. However, with the rise of cross-platform development frameworks, this issue has become more manageable. Two popular choices in this space are Flutter and React Native. In this blog post, we will explore the differences between these two frameworks to help you make an informed decision for your next mobile app project.

What is Flutter?

Flutter is like a magic toolbox for making apps. It's a special kit created by smart people at Google that helps build apps for phones, tablets, and even computers. What's cool about Flutter is that you can make your app look pretty with it. Plus, you only need to write the code once, and it works on both iPhones and Android phones. So, Flutter makes it easier and faster to create awesome apps that work on lots of different devices.

What is React Native?

React Native is another cool tool for making apps, but it's made by clever folks at Facebook. Just like Flutter, it's for creating apps that work on different devices, like iPhones and Android phones. The special thing about React Native is that it uses a language called JavaScript, which many developers already know. With React Native, you can build parts of your app and use them across different devices, making it quicker to create awesome apps for lots of people to enjoy.

History of Flutter and React Native

Flutter, born in 2015, is the brainchild of Google. It started as a way to simplify app development by offering a single code base for both Android and iOS platforms. Over time, it grew stronger, with its official release in 2018, gaining popularity for its speed and beautiful designs.

React Native, created by Facebook, emerged a bit earlier, in 2013. It was initially an internal project, later released to the public in 2015. Facebook introduced it as a solution to develop mobile apps using JavaScript, enabling developers familiar with web technologies to build native mobile experiences. React Native quickly gained traction in the development community due to its flexibility and the vast community support around JavaScript.

Both Flutter and React Native are cross-platform development frameworks, aiming to streamline app creation for multiple devices.

How do Cross-Platform Development Frameworks Work?


  • Single Codebase: Flutter uses Dart programming language. Developers write code once, and it compiles into native machine code for various platforms.

  • Widgets: Flutter has its own set of widgets for building UI components. These widgets are customizable and offer a consistent look across platforms.

  • Rendering Engine: Flutter uses its rendering engine, Skia, to create visuals, ensuring high performance and a consistent UI appearance.

React Native:

  • JavaScript: React Native employs JavaScript and React, a popular web library, to build apps. Developers use components similar to web components to create app interfaces.

  • Bridge for Native Modules: React Native uses a bridge that communicates with native modules, enabling access to device functionalities like cameras or GPS.

  • Native Components: It renders certain elements as native components, ensuring a more authentic look and feel for the specific platform.

Flutter vs. React Native

Programming Language

- Flutter:

Flutter uses Dart as its primary programming language. While Dart is not as widely adopted as languages like JavaScript, it's relatively easy to learn and has excellent documentation.

- React Native:

React Native vs Flutter Google Trends

According to Google Trends, both of them are getting more attention, but since around 2020, Flutter's popularity has been getting bigger compared to React Native. It's like Flutter is gaining more fans over time.

So, if we're talking about which one people seem to like more for making apps that work on different platforms, Flutter seems to be getting more attention. It's like more folks are interested in using Flutter for their projects compared to React Native.

Which is Easier to Learn: Flutter or React Native?

Flutter and React Native are both used to build mobile apps, but they work a bit differently. Learning-wise, Flutter might be a bit easier for beginners. Why? Because it uses a single language, Dart, for both design and functionality, which can be simpler to pick up if you're starting from scratch.

React Native, on the other hand, uses JavaScript, a more widely known language, but it also involves using different tools for design (like JSX) and functionality (like JavaScript). Some find it easier because of its similarity to web development if they already know JavaScript.

So, if you're new to coding, Flutter might feel a bit more straightforward, while React Native might be more familiar if you're already into JavaScript. Both have their strengths, so it might also depend on the specific project or your comfort with a particular programming style!

Backend for Flutter and React Native

Flutter teams up really well with Firebase, which is like a toolbox filled with helpful stuff for apps. Imagine Firebase as a big collection of tools that make it easy to add important things to your app, like user login (authentication), saving and fetching data (real-time database), storing files (cloud storage), and more.

It's all hosted on the internet (in the cloud) by Google, so you don't have to worry about setting up servers or complicated backend stuff. Flutter and Firebase work together smoothly, making it simple to create apps that can do a lot of cool things without needing to build everything from scratch.

React Native, like Flutter, is flexible with backend choices. Since it's based on JavaScript, it can connect with Node.js, Express, or other JavaScript-based backends. It also easily integrates with Firebase, GraphQL, or RESTful APIs.

Both Flutter and React Native can work with a wide range of backend technologies, allowing developers to pick the one that fits their project's requirements or their expertise. So, in terms of backend capabilities, they're quite similar and offer flexibility in choosing the backend technology that suits your needs best.
