Building Cross-Platform Apps: Flutter vs. React Native vs. NativeScript


Cross-platform app development stands as a pivotal pillar in the ever-evolving landscape of mobile application creation. Navigating this dynamic realm involves selecting the right framework, and among the myriad options available, Flutter, React Native, and NativeScript emerge as prominent contenders.

In this article, we delve into the intricacies of these cross-platform frameworks, unraveling their advantages, limitations, and comparative analysis.

What Are Cross-Platform Apps?

Cross-platform app development addresses the demand for versatile applications that seamlessly run on both iOS and Android platforms. The choice of framework significantly influences the development process, and three contenders, Flutter, React Native, and NativeScript, have garnered attention for their unique offerings.

Cross-Platform Frameworks: An Overview

1.   Flutter

Developed by Google, Flutter employs the Dart programming language and a distinctive architecture known as the widget tree. This architecture facilitates the creation of expressive and visually appealing user interfaces.


  • Hot-reload: Enables real-time code changes without restarting the application, enhancing development speed.
  • Expressive UI: Offers a rich set of pre-designed widgets for crafting customized and visually compelling interfaces.
  • Single Codebase: A single codebase for both iOS and Android platforms streamlines development and maintenance.


Smaller Community: Compared to React Native, Flutter has a smaller community, potentially impacting the availability of third-party packages and support.


Well-suited for visually rich applications that demand a high level of customization and a consistent look across platforms.

2.   React Native

React Native, maintained by Facebook, leverages JavaScript and React to build cross-platform applications. Its “Learn Once, Write Anywhere” philosophy emphasizes code reusability.


  • Large Community: Boasts a large developer community, ensuring ample third-party packages and robust community support.
  • Quick Development Cycles: Facilitates quick development cycles with hot-reloading, enhancing developer productivity.
  • Native Modules Integration: Allows easy integration with native modules, providing access to platform-specific functionalities.


JavaScript Bridge Overhead: The JavaScript bridge introduces a performance overhead compared to native applications.

3.  NativeScript

NativeScript utilizes JavaScript, TypeScript, or Angular to build cross-platform applications. It distinguishes itself by enabling direct access to native APIs.


  • Direct Native API Access: Enables direct access to native APIs, offering enhanced customization possibilities.
  • Angular Integration: Seamless integration with Angular, providing a familiar structure for Angular developers.
  • Single Codebase: Like Flutter, NativeScript offers a single codebase for iOS and Android platforms.


Learning Curve: NativeScript may have a steeper learning curve, especially for developers new to Angular.

Comparative Analysis

In this section, we conduct an in-depth comparison of Flutter, React Native, and NativeScript across multiple dimensions.

1 Performance

Analyzing execution speed and efficiency is crucial for app performance. Flutter, with its compiled language (Dart), tends to offer high performance. React Native, leveraging JavaScript, might introduce some overhead, while NativeScript’s direct native API access can enhance performance.

2 Development Speed

Assessing the speed of development cycles involves considering features like hot-reloading. Flutter and React Native excel in this aspect, allowing developers to see real-time changes. NativeScript, with its Angular integration, may have a slightly different development experience.

3 Community Support

Evaluating the size and activity of developer communities is vital for ongoing support and issue resolution. React Native’s extensive community provides a wealth of resources, while Flutter’s growing community may be more specialized. NativeScript benefits from Angular’s community, offering robust support for Angular developers.

4 Ecosystem

Exploring the availability and richness of third-party libraries and tools is crucial for leveraging existing solutions. React Native, with its popularity, boasts a vast ecosystem. Flutter’s ecosystem is growing steadily, while NativeScript leverages the broader Angular ecosystem.

Comparative Strengths:


  • Ideal for visually rich applications.
  • Offers a hot-reload feature for real-time code changes.
  • Provides a single codebase for both iOS and Android.

React Native:

  • Boasts a large developer community.
  • Facilitates quick development cycles with hot-reloading.
  • Allows easy integration with native modules.


  • Enables direct access to native APIs.
  • Seamless integration with Angular.
  • Single codebase for iOS and Android.
