Bridging with Native Components: React Native employs a bridging mechanism to integrate existing iOS and Android code as JavaScript modules. This allows for a seamless blend of native and React components.
Native Look and Feel: Due to its use of native components, React Native ensures that UI elements like buttons appear and behave exactly as they would in native iOS or Android apps.
Adaptability Across Platforms: For applications that require a nearly identical look across different platforms, including older operating system versions, React Native can utilise third-party libraries. These libraries enable the use of Material Design components, offering an alternative to default native components and enhancing cross-platform consistency.

In summary, while Flutter offers a comprehensive, widget-based approach to UI development with a strong focus on consistency across platforms, React Native focuses on integrating with native UI components to provide a more platform-specific look and feel. The choice between the two depends on the desired balance between uniformity across platforms (Flutter) and native component integration (React Native).

Code Sharing in Flutter vs React Native

The approach to code sharing in Flutter and React Native highlights their distinct methodologies and how they manage cross-platform app development:

Flutter’s Code Sharing Approach

Single Codebase: Built on Dart, Flutter offers a distinct advantage by enabling the creation of iOS and Android applications using just one codebase. This approach significantly boosts the reusability of code, often achieving near-total uniformity in code across different platforms. By doing so, Flutter streamlines the development process, allowing for efficient and cohesive app development for multiple operating systems with minimal duplication of effort.
Custom Widgets for Rendering: Flutter uniquely utilises a custom graphics engine for rendering its bespoke widgets, diverging from the reliance on native components seen in other frameworks. This strategy guarantees uniformity in both the behavior and visual presentation of applications across various devices and operating systems. By employing its own rendering system, Flutter ensures that its apps offer a consistent user experience, irrespective of the underlying platform’s specifics.

React Native’s Code Sharing Approach

React Native’s approach to code sharing is characterised by its high degree of reusability and integration with native components. Here’s an outline of this methodology:

High Code Reusability: React Native’s architecture enables the majority of an application’s logic to be written in JavaScript, which is compatible with both iOS and Android platforms. This results in a substantial portion of the code, typically between 80-90%, being reusable across these platforms.
Use of Native Components: By default, React Native leverages platform-specific components, such as translating a React Native Button into an iOS UIButton or an Android android.widget.Button. This ensures that the app’s widgets maintain a native appearance and user experience. This is in contrast to Flutter’s approach, where all components are built from scratch, potentially differing from native components in look and feel.
Inclusion of Native Modules: React Native permits the integration of native code, like Swift for iOS or Java for Android, into its predominantly JavaScript-based logic. This flexibility is advantageous for enhancing app performance or adding platform-specific features. However, it might slightly reduce the overall percentage of shared code across platforms.
Bridging Mechanism: The framework uses a bridging mechanism to enable communication between the JavaScript code and the native modules. While this ensures a smooth integration of native functionalities, it can sometimes lead to performance challenges, particularly in complex application scenarios.

In summary, Flutter offers a more unified codebase with its custom widget approach, leading to a high degree of code reuse and consistency across platforms. React Native, on the other hand, provides flexibility with its use of native components and the ability to include native modules, but this can sometimes result in less code reuse and potential performance considerations.
