On the mobile side, companies like WeChat, ByteDance, Betterment, SHEIN and BMW are now betting on Flutter — as does Google itself.
It does so by relying heavily on Skia, a graphics-rendering engine written in C/C++ that uses a device's CPU or GPU to draw app interfaces on its own, without relying on native platform interface libraries.
In general the design style follows Google's Material Design guidelines, making it particularly at home on Android (as you would expect from Google), but there is also support for Cupertino widgets for a native iOS look and feel.
Flutter now uses Metal by default when building for supported iOS devices, making Flutter apps run faster.
