React or Flutter: Which Framework is Right for Your App?

Category App Development, Product engineering

When we talk about application development, choosing the correct cross-platform app development framework can make or break your application. The question then arises: Why do we need to choose a cross-platform app development framework when legacy systems are still in place? Every operating system requires uniquely written code to run an application. However, writing various codes for one application seems cumbersome and frankly a waste of money, time, and effort. 

To counter this exact issue, cross-platform app development frameworks were developed, meaning the same code can be used by the application to run on various operating systems. This has helped organizations globally save time, cost, and effort for developers. 

The objective of this blog is to deep dive and compare two cross-platform app development frameworks: React and Flutter. By exploring the differences between these frameworks, we aim to help you decide whether React or Flutter is the better choice for your development needs. Let us embark on this learning journey by understanding what exactly React and Flutter offer.

Overview of React and Flutter

React: 

React is a popular JavaScript library designed to build user interfaces for various applications. It allows developers to create reusable components, which are like building blocks for designing UI elements. It follows a declarative approach, meaning developers can focus on what the UI should look like rather than the specific steps to update it. 

Thanks to its highly flexible nature and seamless integrations with other tools or libraries, React has become a go-to framework for developers. 

Origin and background:

Inspired by Lisp, Jordan Walke created React, a library in which developers can create reusable components that can easily be combined to create complex user interfaces.

Facebook employed React to develop the ‘Facebook news feed’. It was later released as an open-source project and gained widespread publicity for its flexibility and ease of use. 

Core features: 

  • One of the main features that has allowed React to become popular is its Reusable Components. This feature allows the component that is built to be an independent building block of the UI, saving the developer’s time and effort.
  • Another popular feature is the Virtual DOM (Document Object Model). This creates a lightweight copy of the real DOM, updating only the necessary parts after comparing changes. This approach improves performance and speeds up applications.
  • The declarative style of programming has proven to be a game changer for developers. Developers just describe how the UI should look on the current application and React makes the changes to match the description, reducing manual intervention. 
  • Unidirectional data flow allows the data to flow in a single direction in the application. This helps the developers analyze how changes in the data are affecting the UI of the application.
  • React also offers a robust ecosystem of tools and libraries that complement its capabilities. Developers can use tools like, React Router for navigation, Redux and MobX for state management, and Next.js for server-side rendering, to build feature-rich and scalable applications.

While Flutter primarily focuses on creating new applications, it can also be integrated into existing codebases. It leverages Drat, a compiled language, and the Sika graphic library, making the application’s performance comparable to Native apps.  

Origin and background:

The Flutter toolkit was developed and released by Google in 2015. It, however, gained traction after Google released the official Hamilton mobile app, the first commercial Flutter app in 2017. The journey of Flutter started when Google identified the need for a single codebase that could be used to develop apps across various platforms. The main goal was to enable developers to write one codebase that works seamlessly on both Android and iOS devices. This approach helps organizations save time and costs when designing applications.

Core features:

  • One of the most helpful features of Flutter is the single codebase feature. Developers can write a single code and deploy it across platforms. The time and efforts of the developers are reduced significantly as the codebase can be used to build applications for web, mobile, and desktop. 
  • The hot reload feature allows developers to see instant updates in the UI during the development phase. This feature allows developers to change and iterate the application’s UI in real-time, making the development process faster and more efficient.
  • Flutter also offers various customizable widgets that can be used to develop beautiful and responsive UI. The widgets provide a consistent look and feel to the application across platforms as it is designed to adapt to different screens. 
  • Flutter allows developers to easily access native device features like sensors, cameras, geolocation, and platform-specific services, enabling seamless use of native capabilities.
  • Flutter has a thriving ecosystem with a wide range of packages and plugins available. These tools provide pre-built solutions for common app functionalities like networking, state management, animations, and more. This extensive library helps developers save time, reduce effort, and accelerate the development process.

Where to use Flutter:

  1. Cross-Platform Mobile Applications:
    Flutter is designed for building natively compiled applications for mobile, web, and desktop from a single codebase. This makes it ideal for startups and businesses looking to reach a wide audience across multiple platforms without the need for separate codebases.

    • Flutter uses Dart, a programming language developed by Google. Developers who are new to Flutter may need to learn Dart, though it is designed to be easy to pick up.
  2. Performance
    • React apps use a JavaScript bridge to interact with native components, which can sometimes lead to performance bottlenecks, especially in complex apps. This bridge adds a layer of communication between the JavaScript code and the native components, which can affect the app’s performance on lower-end devices.
    • Flutter, on the other hand, compiles directly to native code without the need for a bridge. This direct compilation offers better performance, especially for more graphically intense apps, providing smoother animations and faster rendering, as everything is built in native code.
  3. UI Components
    • React relies on the use of native components provided by the platform. This means React apps follow the look and feel of the native platform (iOS or Android) by using the platform’s default components like buttons, navigation bars, etc. This can be beneficial for creating apps that look and behave like native apps.
    • Flutter uses its customizable widgets. These widgets are not tied to native components, meaning they provide a consistent look across different platforms. While this ensures that your app looks the same on both iOS and Android, it also means that developers need to rely more on Flutter’s design patterns to achieve the desired user experience.
  4. Ecosystem
    • React has a mature and extensive ecosystem. It has been around since 2013 and has a vast collection of libraries, tools, and community support. The availability of resources and third-party libraries can significantly speed up the development process.
    • Flutter’s ecosystem is still growing but has been expanding rapidly since its release in 2018. While it provides a lot of libraries and tools, some third-party libraries may not be as mature as those available for React. However, the Flutter community is active and continuously adding new packages, making it a robust option for developers.
  5. Development Features
    • React has robust development tools and features that are particularly useful for web development. It supports Hot Reload, which allows developers to instantly see the changes they make in the code reflected in the app without refreshing the whole application. However, React is primarily focused on web development, and when building mobile apps, developers use React Native, which comes with its own set of challenges and tools.
    • Flutter also supports Hot Reload, allowing developers to make changes to the app’s code and instantly see the results, making the development process faster and more efficient. Flutter provides a single codebase for both web and mobile apps, streamlining development for multiple platforms. It has a rich set of pre-built widgets and tools for UI, helping developers design the app’s interface with minimal effort.
