React Native quickly gained traction in the development community due to its flexibility and the vast community support around JavaScript.

Both Flutter and React Native are cross-platform development frameworks, aiming to streamline app creation for multiple devices.

How do Cross-Platform Development Frameworks Work?

Flutter:

• Single Codebase: Flutter uses Dart programming language. Developers write code once, and it compiles into native machine code for various platforms.

• Widgets: Flutter has its own set of widgets for building UI components. These widgets are customizable and offer a consistent look across platforms.

• Rendering Engine: Flutter uses its rendering engine, Skia, to create visuals, ensuring high performance and a consistent UI appearance.

React Native:

• JavaScript: React Native employs JavaScript and React, a popular web library, to build apps. Developers use components similar to web components to create app interfaces.

• Bridge for Native Modules: React Native uses a bridge that communicates with native modules, enabling access to device functionalities like cameras or GPS.

• Native Components: It renders certain elements as native components, ensuring a more authentic look and feel for the specific platform.
