Why Flutter app is fast?

It is a client-optimized language for fast performing apps on multiple platforms. Dart is AOT (Ahead Of Time) compiled to fast, predictable, native code, allowing writing almost all of Flutter code in Dart. This makes Flutter extremely fast and customizable.

CPU-intensive test (Gauss–Legendre algorithm) for Android Flutter is approximately 20% slower than native . React Native is around 15 times slower than native.

They are fast, pretty, and customizable , Thanks to the rich widgets, Flutter apps look and feel great (you can create your own custom app design, but also use readily available UI elements following specific platforms’ guidelines).20 Oca 2021
