What does frame rate genuinely mean in the context of a Flutter app, and why is consistently maintaining roughly sixty frames per second generally considered the ideal, genuinely smooth target for typical mobile devices?

Frame rate refers to exactly how many individual complete frames your app can actually successfully render and display every single second, and consistently maintaining a rate of roughly sixty frames per second, meaning each individual frame needs to be fully rendered within roughly sixteen milliseconds, is generally considered the standard, ideal target for a genuinely smooth, fluid feeling animation and scrolling experience on most typical mobile devices, and whenever a specific frame actually takes noticeably longer than that available sixteen millisecond budget to properly render, the resulting visible stutter is generally referred to as jank, which users can genuinely and quite easily notice, particularly during scrolling or animation.
