Each application we build is at once a mobile application, a web application and a desktop application (Windows, Mac and Linux), and it shares much of its code with the server-side services we build to provide computation and storage, all using a single programming language and platform, the Dart^TM language, developed by Google.

Our in-house built server-side framework for the Dart language coupled with the Flutter^TM framework, by Google, to build universal client apps enables us use Dart as a single, full-stack language, to build everything.

Here's a table comparing our old options to our new, Dart-based approach:

	Typical traditional approach*	Dart as a universal language
Backend Server	C#, VB.Net, Java, Python	Dart with Dartaculous
Web application client	JavaScript / TypeScript / WebAssembly + HTML + CSS + jQuery / Angular / ReactJS / Vue /...	Dart with Flutter
Desktop Application	Windows Forms / WPF / UWP / Xamarin Forms (Windows) ObjectiveC / Swift (MacOS) GTK / GTK# / QT / ... (Linux)
Mobile Application	Native (Swift, Android [Java/Kotlin]) / Xamarin / React Native / Ionic / ...

Which do you think is more reliable and which will cost less to build, maintain and expand?

* As we have decades of experience with the .Net framework and SPA frameworks, we also develop and maintain applications the old fashioned, complex way, when you, the customer, needs it that way.
