react native vs flutter

Mobile application development continues to grow in popularity, companies are seeking ways to develop cross-platform applications which can be utilized across a range of devices.

The article we’ll examine two frameworks that are popular that allow cross-platform development: Flutter and React Native.

What is Flutter?

Flutter is an open-source mobile app development framework developed by Google. It was first released in the year 2017 , and since then has grown in a lot of attention in the world of developers due to its rapid development speed, its expressive and customizable UI, as well as its capability to build powerful mobile applications to the iOS as well as Android platforms using one code base.

Flutter utilises the Dart programming language and offers an array of pre-built widgets and other tools which allow developers to design appealing and user-friendly interfaces. The framework also comes with the hot-reload feature that lets developers see modifications that they’ve made in their program immediately without restarting the application which makes the process of developing quicker and efficient.

Furthermore, Flutter has a strong and growing community of users that provide an extensive set of documentation, tutorials and plug-ins, making it much easier for developers to understand and utilize the framework. Flutter is a great tool to create a variety of applications, from basic prototypes to sophisticated enterprise-level apps.

What is React Native?

React Native is an open source mobile app development framework developed by Facebook. First came out in 2015 and has since become an extremely well-known framework for creating native mobile applications development that run on iOS as well as Android platforms with the same codebase.

React Native makes use of the React framework that is widely used in web development. It allow the developers to create mobile applications using JavaScript as well as React syntax. React Native offers a set of pre-built elements that allow developers to build sophisticated user interfaces quickly and effectively.

One of the major advantages that comes with React Native is its capability to make use of a single source code base to build mobile applications that work on various platforms. Developers write one codebase and publish simultaneously on iOS or Android platforms, saving time, and development costs.

React Native also offers hot-reloading which allows developers to view the modifications that they’ve made in their application in real-time without having to rebuild the application. This allows developers to develop easier and faster.

In the end, React Native is a powerful tool to develop native mobile applications that provide the same functionality and user experience that apps created using native frameworks for development, such as Java or Objective-C/Swift.

The History of Flutter and React Native

The Flutter framework and React Native Two well-known frameworks for mobile app development which have gained popularity in recent times. This is a brief overview of the two frameworks:


  • Flutter was announced for the first time in the early days of Google at the end of May 2017, during the Google I/O conference.
  • First stable Flutter version Version 1.0 was released in December of 2018.
  • Since its introduction Flutter has grown in popularity with developers. Flutter has also been utilized to create apps for companies like Alibaba, Google, and Tencent.

React Native:

  • React Native was initially launched by Facebook in the year 2015, and was an expansion of the React Web Development Framework.
  • Since its introduction, React Native has become one of the most used frameworks for mobile app development, employed by companies like Facebook, Airbnb, and Instagram.
  • React Native has undergone several major updates, the most recent being version 0.70.6.

Both frameworks are gaining popularity with a large number of developers, and they continue to develop to meet the ever-changing requirements of mobile application development. Although Flutter as well as React Native have some similarities in their capability to create mobile apps that are high-performance with a single source code base, they have some significant differences in the way they use their languages of programming, their architecture and available features. 

Why are React Native and Flutter so popular?

React Native as well as Flutter are popular mobile frameworks for developing apps:

  1. Development for Cross-Platforms: The both frameworks let developers to create applications that work on each of the iOS as well as Android platforms from one codebase. This drastically reduces development time and costs, since developers do not have to write code on each device.

  2. Hot Reloading: Both Flutter along with React Native offer hot reloading which lets developers observe changes to their code in real time without having to build the app again. This makes development quicker as well as more effective.

  3. Rich set of pre-built components: Both frameworks offer a rich set of pre-built components and widgets, which makes it easy for developers to create complex user interfaces quickly and efficiently.

  4. Strong community support: Both frameworks have a robust and expanding community of programmers who work on the frameworks, offer assistance and advice, and also offer their expertise and knowledge.

  5. Performance:Flutter along with React Native are designed to offer high-performance applications that feature speedy loading time, fluid animations with a natural look and feel.

  6. Easy to learn: It is easy to master Frameworks that are well-known programming languages (Dart to create Flutter along with JavaScript in React Native), which makes it simple for developers to understand and use the frameworks.
