Flutter GUI Development

Flutter is an open-source framework backed by Google for building beautiful, natively compiled, multi-platform applications from a single codebase.

Flutter is one of the GUI development frameworks that Witekio engineers turn to for clients who require a single, easily managed codebase that delivers a consistent user interface across mobile, desktop, and connected device platforms.

Why Choose Flutter?

Flutter has some distinct advantages for building cross-platform graphical user interfaces for connected and embedded devices. Among the advantages of developing your GUI with Flutter are:

• Flutter is fast. Whether you are compiling to Arm machine code, Intel machine code, or JavaScript, Flutter is designed for performance that touches on native app speed for every platform.
• Flutter is productive. Flutter’s Hot Reload feature means that development is rapid, iterations of the codebase are quick to deploy, and code can be updated and reviewed almost instantly.
• Flutter is flexible. Flutter offers developers the opportunity to control every pixel in the UI. Adapting and customizing a GUI is simple and – no matter the screen size – the interface looks and feels great.
• Flutter is cheaper. Developing mobile applications for both the Android and iOS platforms means having two teams of developers and two codebases to maintain. With Flutter it’s one team and one codebase.
• Flutter is truly cross-platform. Originally focused only on mobile operating systems Android and iOS, today there is support for Linux thanks to Google’s collaboration with Ubuntu owners Canonical.

If there’s a downside to Flutter, it’s the same as any other cross-platform GUI development framework: a Flutter application is likely to be a little less efficient and a little more memory-hungry than a native app.

However, considering the cost and time savings that Flutter delivers, and the flexibility and productivity that developers can expect, it’s a trade-off many are willing to make.

Flutter in Action 

Household names like eBay, Google, BMW, Toyota, the Alibaba Group and Tencent have all embraced Flutter and deployed applications to hundreds of millions of end users worldwide with positive results. 

The Google Pay team, for example, wanted to unite their mobile payments codebase between Android and iOS. With the native applications each requiring the upkeep of 1.7 million lines of code each, there was an enormous engineering effort involved in keeping the two applications aligned and up to date.

Thanks to Flutter the Google Pay team: 

• Optimized more than 3.4 million lines of code across separate Android and iOS applications 
• Reduced the number of lines in the codebase by 35% 
• Reduced their engineering spend by 70% 

Lower costs, greater efficiency, and simpler code – that’s the promise of Flutter
