Creating a user interface (UI)

And now let's take a closer look at the differences between React Native and Flutter. One of them concerns the creation of a user interface.

React Native uses native components of the iOS and Android user interface. Therefore, the components of the React Native application look the same as the components of the corresponding platform. If the OS update changes the appearance or functions of these components, they will be updated in your application in the same way. The plus is that you may have to release new releases less often, and the minus is that OS updates can disrupt the operation of your application.

Flutter, instead of using native app UI elements, offers customizable widgets that are drawn from scratch. UI development using Flutter involves extensive customization. You can use the Cupertino widget library to make the interface look native, or you can create something completely individual. You have the option to use and adapt any widget in the Flutter library or develop your own widgets.

From the business point of view

Both Flutter vs React Native separate the user interface from the business logic of the application. Flutter employs the block method, while React Native follows the Flux pattern. The block pattern, used by Flutter, ensures smooth scrolling and animations even during data loading through asynchronous methods, structured coding, and multithreading.

React Native offers the advantage of reusing the business logic across different platforms, leading to faster development and reduced error rates. Additionally, React Native benefits from a vast ecosystem of JavaScript libraries, expanding its capabilities.


In terms of documentation, Flutter framework takes the lead with its excellent documentation, making it beginner-friendly and easy to get started with. React Native's documentation assumes some prior knowledge of JavaScript, making it relatively more complex for newcomers.

Both Flutter vs React Native have sizable and active communities. As of May 2022, Flutter boasts 121 thousand stars on GitHub, while React Native has 95.6 thousand. The Flutter community shows consistent growth and high engagement across platforms like Reddit, Stack Overflow, Facebook, and Twitter. This active community support indicates that the future of cross-platform application development is leaning toward Flutter.

Efficiency and Performance

Performance is a critical factor to consider when selecting Flutter vs React Native vs Xamarin, and Flutter excels in this aspect. Flutter's efficient code-writing process, combined with its C++ engine and the Skia graphics library, enables the creation of high-performance applications for various platforms.

React Native, on the other hand, relies on a bridge that connects JavaScript and native code, which can sometimes lead to delays in UI rendering and other performance issues. Flutter, with its direct integration with native elements through built-in libraries and frameworks, bypasses such challenges.

When choice of React Native is better than Flutter?

Choosing between Flutter vs React Native depends on various factors related to your project's requirements, team expertise, and development goals. Here are some scenarios where React Native might be a better choice:

  1. Familiarity with JavaScript and React:

    • If your development team, app developers are already well-versed in JavaScript and React, transitioning to React Native can be smoother since the same programming language and library are used.

  2. Integration with Existing Web Codebase:

    • If your project involves integrating with existing web code or services, React Native's JavaScript-based approach might make integration easier.

  3. Third-Party Libraries and Modules:

    • If your project requires extensive use of third-party libraries or modules, React Native's mature ecosystem and extensive npm package repository can provide a wider range of options.

  4. Platform-Specific Customization:

    • If your app needs extensive platform-specific customization or relies heavily on native modules, React Native framework's ability to write platform-specific code can be advantageous.

  5. Established Community and Resources:

    • If you value a large and established developer community with abundant resources, tutorials, and support, React Native has been around longer and has a well-established presence.

  6. Team Expertise and Transition:

    • If you have a team with strong JavaScript skills and you're considering transitioning from web to mobile development, React Native could provide a smoother learning curve.

  7. Shorter Development Timeline:

    • If your project demands a quicker development cycle, React Native's hot reload feature might allow for faster iterations and testing.

  8. Small to Medium-sized Projects:

    • If you're developing a relatively simple or small-scale app, React Native's quicker development process could be a good fit.

  9. Cross-Platform Flexibility with Some Platform-Specific Code:

    • If you want to share the majority of your codebase while still having the flexibility to write some platform-specific code for optimization or customizations, React Native allows for this hybrid approach.

  10. Availability of Skilled Developers:

    • If you're seeking to hire developers, the pool of JavaScript developers is generally larger, making it potentially easier to find skilled professionals for your React Native project.

In essence, choose React Native when your team's expertise, project requirements, and development goals align with the strengths of the framework. React Native is a popular choice for businesses and developers who want to leverage their JavaScript skills, build cross-platform apps efficiently, and take advantage of the extensive React Native ecosystem.

When to choose Flutter instead of React Native?

Choosing between Flutter vs React Native depends on the specific needs of your project and the strengths of each framework. Here are scenarios where choosing Flutter might be a better fit:

  1. High-Quality and Consistent UI: If achieving a highly polished and consistent UI across different platforms is a top priority, Flutter's widget-based architecture allows for more control over the visual appearance and behavior of your app.

  2. Custom Animations and Rich UI: If your app heavily relies on complex animations, custom transitions, or intricate UI elements, Flutter's built-in animation framework and powerful widgets can provide a smoother and more flexible experience.

  3. Performance-Centric Apps: If your app requires high performance, Flutter's compilation to native ARM code and utilization of the Skia graphics engine can result in better performance compared to some JavaScript-based solutions.

  4. Single Codebase for Multidimensional Apps: If you're developing apps that need to target mobile, web, and desktop platforms from a single codebase, Flutter's multi-platform support might be more appealing.

  5. Real-Time Apps and Games: If you're building real-time apps, games, or interactive experiences that require rapid and smooth updates, Flutter's performance advantages can be advantageous.

  6. Consistent Design Language Across Platforms: If you want to follow a consistent design language for both Android and iOS, Flutter's built-in Material Design and Cupertino widgets provide native-like interfaces for both platforms.

  7. Faster Development of Complex UI: If your development team is skilled in Dart and you need to develop complex UIs quickly, Flutter's declarative UI approach and hot reload can accelerate development iterations.

  8. Startup and Prototyping: If you're a startup looking to quickly prototype an idea or build a Minimum Viable Product (MVP), Flutter's rapid development cycle and hot reload can help bring your concept to life swiftly.

  9. Newer Projects with Long-Term Vision: If you're starting a new project and anticipate the need for a consistent and future-proof solution, Flutter's growing community and Google's backing might provide confidence in its long-term viability.

  10. Limited Platform-Specific Customization: If your app can prioritize a more uniform experience across platforms and doesn't require extensive platform-specific customizations, Flutter's consistency might align with your goals.

In summary, choose Flutter mobile app development framework when your project demands a high-quality, consistent UI, performance optimization, and the flexibility to target multiple platforms from a single codebase. If your team is comfortable with Dart and you're aiming for a native-like experience with custom animations and rich UI, Flutter's features and capabilities make it a strong contender.
