Why Flutter? From the Perspective of a JavaScript & SvelteKit Studio

As a team experienced in building web projects with JavaScript and SvelteKit, we always try to keep up with new technologies and trends. Recently, Flutter has stood out in the world of mobile and cross-platform development, so we decided to give it a try. We often asked ourselves, “Why Flutter instead of React Native?” In this blog, we wanted to share our own experiences and observations.

Our introduction to Flutter

Flutter is a framework developed by Google that allows you to build apps for mobile (iOS/Android), desktop (Windows, macOS, Linux), web, and even embedded devices—all from a single codebase. The support for desktop and embedded devices was especially appealing to us at first. Previously, we had developed mobile apps with Kotlin, Java, or Swift, but Flutter’s single codebase and broad platform support made it our preferred choice.

Why Flutter? Why not React Native?

React Native certainly has the advantage of being close to the JavaScript ecosystem. However, Flutter’s widget-based structure, its own rendering engine, and platform-independent UI consistency really impressed us. Especially for animated and custom-designed apps, Flutter’s flexibility and stability put it ahead of React Native in our experience. There are other alternatives like Ionic, Capacitor, Framework7, and Svelte Native, but Flutter’s strong backing by Google and its continuous updates make it more attractive.

Dart’s type-safe structure helps prevent the “runtime error” surprises we often encounter in JavaScript. Catching errors at compile time saves a lot of time in large projects. Of course, TypeScript can minimize such issues as well.

While React Native is limited in developing apps for IoT and embedded devices, Flutter stands out in this area.

Flutter also has its own game library, Flame, which has serious potential for 2D game development. This allows us to consider Flutter for future game projects as well.

The ease of Flutter’s API

Flutter’s API is especially easy to understand for beginners. The widget logic feels very natural for those used to component-based thinking. With hot reload, we can instantly see the changes we make in the code. This speed significantly improves the developer experience (DX), especially during UI development.

Flutter 3.32 and what’s new

As of May 20, 2025, Flutter has reached version 3.32. There are many new features, such as experimental hot reload support for web, easy creation of rounded designs for iOS with Cupertino Squircles, new widgets like Expansible and RawMenuAnchor, easy use of AI models with Firebase AI integration, and platform-specific improvements.

What kind of projects do we prefer Flutter for?

  • Fast MVP development processes
  • Projects that require both mobile apps and desktop or web interfaces
  • Apps where UI/UX is a priority, with rich visuals and animations
  • Projects that need multi-platform support
  • IoT and embedded device applications (in our future projects)
  • Game projects (especially 2D)

Why do we prefer Flutter over Ionic, Capacitor, Framework7, Svelte Native, and PWA?

For web and mobile-focused projects, especially MVPs, we prefer Flutter because it is more stable, better maintained, and has a stronger community compared to technologies like Ionic, Capacitor, Framework7, Svelte Native, and PWA. When creating mobile extensions of our web-based projects or developing mobile apps from scratch, Flutter allows us to speed up the development process and achieve more reliable results.

The advantages of Flutter

  • Single Codebase: Use the same code for mobile, desktop, web, and embedded devices
  • Type-safe Dart: A robust language that catches errors early
  • Stability: Consistent UI independent of platform, thanks to its own rendering engine
  • API: Widget-based, enabling fast development
  • Rich Ecosystem: Many integrations are possible thanks to package and plugin support

In summary

As we bring our web experience to mobile and other platforms, Flutter has given us both speed and flexibility. Of course, Flutter isn’t necessary for every project; but for projects targeting multiple platforms, where user experience and functionality are important, it’s definitely worth considering.

If you want to bring your project to mobile, desktop, or web, we can help you evaluate whether Flutter is right for you. We’re always here to share our experiences and contribute to your projects!
