Flutter benefits

A single codebase

As an app development company with the Flutter expertise, we create solutions with a consistent business logic implemented across several platforms, sparing the need to deliver platform-specific functionality, thus saving valuable man-hours.

A customizable user interface

Flutter represents a fully fledged software development kit comprised of API interfaces, customizable widgets, visualization tools, etc. Thanks to its cross-platform capabilities, all the functionality is seamlessly deployed across multiple operating systems (iOS, Android, Windows, Linux, etc.).

Faster developments

Implement user interface (UI) elements, update the existing functionality, or fix critical issues on the fly without requesting end users to refresh app’s content by clearing cache, force-stopping an app, etc., which may cause the loss of unsaved data.

Better app performance

Thanks to a well-designed architecture, the Flutter framework promotes optimized performance, faster loading times, low latency, etc.

Upgrading existing apps

Enhance your existing apps with interactive UI features, such as menus, buttons, sliders, etc., without the need to tweak the code.

Based on Dart

Dart is an open-source programming language developed by Google with a strong community behind it. Thanks to its flexibility and portability, the language is well-suited for writing cross-platform apps. In addition, its clean and concise syntax contributes to facilitating the adoption curve for developers.

Ideal for prototyping

Hire dedicated Flutter developers at Altoros to build a minimum viable product and easily check the idea’s feasibility on target platforms, receive early feedback from real users, and deliver a strategic roadmap for improvements.
