How does Flutter achieve consistent 60fps rendering?
Answer
Flutter achieves consistent frame rates by owning every pixel on the screen through its own graphics engine (Skia, now transitioning to Impeller). Unlike React Native which bridges to native components, Flutter renders its own widgets directly to the canvas — there is no OEM widget translation layer that could cause jank. The Dart VM's low-latency garbage collector avoids long GC pauses. Flutter's animation system is synchronized with the display refresh rate (vsync). And const widgets, RepaintBoundary, and lazy list builders prevent unnecessary work each frame.
