• Native integration: Ideal for projects needing deep links to device features such as GPS or Bluetooth.
• Ecosystem: Mature, with plenty of third-party plugins and support for both enterprise- and consumer-grade apps.

React Native’s established reputation and vast developer pool make it a safer investment for many organisations focused on scalability and ongoing support.

Key Advantages of React Native

• Code reusability: One codebase for both platforms.
• Lower development costs: Quicker releases and simplified maintenance.
• Strong community: Easy hiring and global support.
• OTA updates: Over-the-air updates without waiting for app store approvals.
• Native-like UX: Apps look and feel close to native, ensuring seamless experiences.

React Native powers high-profile apps like Facebook, Instagram, Skype, and Bloomberg, testifying to its robustness and versatility.

Major Disadvantages of React Native

Despite its strengths, there are some significant limitations:

• Performance overhead: The use of a bridge can sometimes affect intensive animations or real-time features, even though recent improvements narrow the gap.
• Device-specific features: Advanced native module access occasionally demands writing custom Java/Kotlin or Swift/Objective-C code, complicating project requirements.
• App size: Larger than pure native apps, which can impact initial download times on low-end devices.
• Debugging challenges: Debugging cross-platform issues may require experience in both native and JavaScript environments.
• Dependency on third-party tools: Heavy reliance can sometimes cause upgrade or compatibility headaches.

Why Choose React Native over Flutter?

Selecting React Native vs Flutter could be the right move for businesses that:

• Already have a React/JavaScript team and want to minimise the learning curve.
• Require rapid prototyping, leveraging existing React web components for mobile expansion.
• Need robust integration with legacy or existing native components.
• Value the backing of Meta and the mature plugin ecosystem.

For specific projects—particularly those prioritising fast shipping, broad talent pools, and deep native features—React Native rises to the top.

What Is Flutter Framework?

Flutter is Google’s open-source UI toolkit launched in 2018. It enables the development of natively compiled applications for mobile, web, desktop, and embedded devices from a single Dart codebase.

• Language: Dart, designed for performance and scalability.
• Rendering engine: Custom, proprietary (recently upgraded to Impeller for superior GPU utilisation).
• UI consistency: Renders UI on its own canvas, giving designers granular creative control.

Flutter has become extraordinarily popular, boasting a 42% market share in cross-platform mobile development in 2025, with an ever-rising global footprint.

Core Things We Need to Know About Flutter

• Popularity: Now the most preferred cross-platform framework globally, ahead of React Native by about 4% in usage as of 2025.
• Performance: Compiles directly into native machine code. Its GPU-optimised Impeller engine supports rich animations, making it perfect for visually demanding apps.
• UI design: Offers pixel-perfect, consistent UIs regardless of device, due to its self-rendering approach.
• Platform reach: Supports Android, iOS, web, desktop, and even embedded devices across automotive and IoT sectors.

Flutter’s comprehensive documentation, widget library, and clean architecture have won over start-ups and big tech alike.

Difference Between Flutter and React Native

Understanding the difference between Flutter and React Native comes down to architecture, performance, and target user base:
