What is Flutter? When and Why You Should Use It in App Development

What is Flutter app development? This toolkit is a cross-platform technology from Google, that allows creating application programs for mobile, desktop, and web use. It utilizes the Dart programming language, which in turn is based on the notorious Java. If you know Java/C#, assume you can program with Dart. The technology keeps up with the latest developments and is used by developers around the world. Most importantly, it is open-source and completely free.

10 Reasons to Choose Flutter for Your App

Cross-platform applications are a long-standing dream of any business, because separate native iOS and Android apps are more expensive to develop and maintain. Flutter offers a quick way to create visually attractive apps for both operational systems, desktop computers, and the web from a single codebase. It is actively used and promoted by Google, and we expect that it will become universally popular in the near future.

Flutter vs Xamarin

Nowadays, there are several cross-platform mobile development tools that help companies reduce development time, maintenance costs, and attract more users. Such tools include Intel XDK, Xamarin, Cordova, and Flutter. Here, we will focus on Xamarin and Flutter by comparing their strengths and weaknesses, to help developers choose the best tool. Why Xamarin? Because this Microsoft framework is arguably one of the top cross-platform development toolkits.

Application performance

Application performance is the most important factor to consider when choosing a framework for cross-platform application development. However, application performance is difficult to evaluate because it depends on many factors and variables, including device, code, applications, and functions.


There’s no doubt that Xamarin has built up a very extensive user base since its release back in 2011. At the same time, Flutter is one of the newest and most promising development platforms on the market right now. The Flutter toolkit is quickly gaining popularity in the developer community.

Development language

When choosing a framework, it is also important to consider the development language of a cross-platform tool. Xamarin uses .Net languages ​​such as C# and F#, which can also be used to write native platform code. The Flutter framework uses Dart, which was not initially invented for mobile platforms but has been well-adapted for developing mobile applications.


Flutter promises an extensive library of components called widgets which are not adaptive to the kernel. It offers widgets both for iOS and Android. However, developers must initiate a manual switch between them, since Flutter does not have components that automatically adapts their style. Meanwhile, Xamarin.Forms comes with a complete cross-platform user interface toolkit consisting of its own UI components for both platforms. Xamarin.iOS or Xamarin.Android can also be used for the user interface of an application and for improving performance.

Code reusability

Code reusability is a major factor that encourages developers to create cross-platform applications. So the main question is: how much code written for each platform can really be reused?


In theory, both tools are free open-source platforms. However, Xamarin is open only for use by individuals and small companies. For large application development companies, the cost of a single-user license starts at $499 and increases to $2,999 for an annual subscription to Visual Studio Enterprise. That’s why a lot of companies choose Flutter instead of Xamarin.

When Flutter Should Not Be Your Choice

This powerful framework that allows creating multifunctional applications is suitable for both beginners and experienced programmers — high speed, convenience, and simplicity. However, it has some flaws, especially when creating apps in the following situations:

  1. Or you can try creating the feature for both iOS and Android platforms simultaneously with the help of FlutterBle, a Bluetooth plugin for Flutter.

What Apps Can Be Made With Flutter?

In simple terms, any. Nowadays, Flutter is widely used to create applications for Alibaba, Yandex, Airbnb, Uber, and other large companies. With the help of Flutter, you can develop applications for:

  • banks and fintech (work with small businesses);
  • suppliers and franchisees;
  • large business (contact centers, courier control, organization of internal processes).

Our Conclusion

Designed to create high-performance applications in record time, Flutter helps developers avoid so many problems that it is difficult to list them all here. To fully appreciate this software development kit, you need to test it in practice.

  • Similarity to native app performance
  • Suitable for web and desktop browsers
  • Own graphics engine
  • Simple logic implementation
  • Great designs
  • Customizable kit of widgets
  • Hot reloading function
  • The final installation package is larger
