1. Rendering Engine Benchmarks: Impeller vs UIKit/Jetpack

Flutter's new Impeller engine compiles shaders ahead of time (AOT), eliminating UI stutter (jank) and delivering silky 120 FPS animations on modern ProMotion displays.

  • Time-to-market: 4–8 weeks with Flutter vs 10–16 weeks with dual native teams.
  • Single design system consistency across both operating systems.
  • Native code interoperability via platform channels when custom hardware access is required.
