Flutter Technology: Benefits and Limitations of Building Mobile Apps

Mobile apps are the backbone of digital business — from fintech startups to global e-commerce, nearly every company needs a high-quality app to engage users, drive revenue and scale. Choosing the right framework is a key strategic decision, and Flutter — Google’s open-source UI toolkit — has emerged as a leading cross-platform solution.

The rise of Flutter

Introduced by Google in 2017, Flutter is now used by around 12.6% of developers worldwide — the most widely adopted cross-platform framework, ahead of React Native — with 158,000+ GitHub stars by 2024. Alibaba, BMW, eBay Motors and Google itself rely on it for critical apps.

Why companies choose Flutter

A single codebase runs on both iOS and Android — faster development and savings of up to 40% versus fully native. Hot reload shows code changes instantly for fast iteration. Flutter compiles to native ARM code, so animations and responsiveness rival native apps. And its rich, customisable widget library produces modern UIs without heavy external dependencies.

The limitations

Flutter apps tend to be larger in file size — a concern where storage or bandwidth is limited. Some advanced native APIs (BLE, AR, very specific device functions) may need extra plugins or custom native code. And the Flutter talent pool, while growing, is still smaller than for Swift or Kotlin — which is why we help clients quickly find experienced Flutter engineers in Lithuania and across Europe.

The future

Google is extending Flutter beyond mobile to web, desktop and embedded devices — positioning it as a truly universal cross-platform toolkit. For most startups and scale-ups, its mix of cost efficiency, speed and quality makes it an excellent choice — provided you weigh its limits for projects needing advanced native features or minimal app size.
