Measure power consumption and framerate (especially for scrolling scenarios) rather than CPU usage before making any performance claims for mobile.

Flutter uses the Chrome rendering engine (Skia) and scrolling is fully fluid (in release mode). React native uses native views (if implemented correctly) and is usually very fluid too

I tried a flutter app i found from the sample app catalog on the iOS store on an iphone X and the scroll wasn't really good (although the views were very basic).

Can you point me at an iOS app made with flutter that implements this correctly on the store ?

EDIT : it's the "veggie season" app and i've tried it again on my iphone 6. it's almost unusable. The scroll stops completley sometimes and other times it just scrolls randomly to places. It's just a scroll list of images. Nothing else. That's very troubling..

I had the same experience.

Flutter devs like to throw some wild claims like "120 fps on mobile" even though no Android phone screen support 120 frames per second at the hardware level and that all the flutter apps I have seen stutter a lot in their animations.
