  User Interface and Design

  Flutter leverages customizable widget sets to help developers design intricate and unique UIs with ease. These widgets are regarded for their adaptability, enabling developers to achieve precise and polished designs. It uses a single codebase that makes applications look and behave the same on Android and iOS, irrespective of the operating system version. It uses a single codebase that makes applications look and behave the same on Android and iOS, irrespective of the operating system version.

  It has two distinct sets of widgets that adhere to specific design languages: Material Design Widgets that represent Google’s design language, and Cupertino widgets that reflect Apple’s iOS design. Also, Flutter employs its own rendering engine to create UI components, ensuring consistency across different platforms and delivering a unified user experience.

  On the other side, React Native provides a bridge that integrates pre-existing iOS and Android code as JavaScript modules. Additionally, it furnishes APIs that streamling manual bridging between native UI elements and their JavaScript rendering counterparts. As a result, application components mirror native elements closely. You can imagine a button on an iOS device closely resembling a native iOS button, and likewise on Android.

  Development Speed

   

  Flutter’s hot reload capability, single codebase approach, and extensive collection of customizable widgets streamline and accelerate development processes. Its hot reload capability is among the prime reasons why businesses and startups choose Flutter for mobile app development.

  However, for applications with complex UI elements, developers may have to add separate code files for iOS and Android platforms, which can elongate the development cycle.
