Flutter for iOS and Android: A Unified Code Base for Your App

In the dynamic world of mobile app development, companies are constantly ahead of the strategic decision.

Should separate, native apps be built for iOS and Android, or is a cross-platform solution of the more efficient way?

The latter promises accelerated development, reduced costs and simplified maintenance. Two of the most prominent candidates in this area are Flutter and React Native.

Both frameworks have a great support and are supported by technology giants. But what is the best choice for your specific project?

This post provides a detailed review and a complete comparison to provide you with a sound basis for decision Flutter vs React Native.

What is Flutter?

Flutter is an open source UI toolkit created by Google that allows developers to create visually appealing and high-performant applications for a variety of platforms from a single code base.

This includes iOS, Android, Web, Windows, macOS and Linux. Programming is done in Dart, a modern, object-oriented language built by Google.

A key characteristic of Flutter is its architecture.

It bypasses the native UI components of the operating system and renders the entire user interface with its own, highly improved graphics engine called Skia (and future Impeller).

The result is a pixel-precise control and a consistent appearance across all platforms.

The core benefits of Flutter

Flutter has quickly proven itself as a preferred choice for many developers and companies, resulting in a number of convincing benefits:

• Excellent and predictable performance: Due to the direct compilation of the dart code in native ARM machine code and the bypass of the JavaScript bridge, which is often a bottleneck in other frameworks, Flutter achieves a performance that hardly differs from native applications. Complex animations and data-intensive lists run consistently liquid with 60 or even 120 images per second.
• Maximum design freedom and consistency: Because Flutter is not dependent on the UI elements of the target platform, designers and developers have the complete freedom to design customized and new user interfaces. This "Write Once, Run Anywhere" principle ensures that brand design and user experience are exactly the same on each device.
• Accelerated development cycle: A key feature that developers love on floodter is the "Stateful Hot Reload". It allows to see changes to the code in milliseconds in the running app without losing their condition. This accelerates experimentation, troubleshooting and g.
