Why does double.floor have bad performance?
ContextWhile porting KdotJPG's OpenSimplex2 to Dart (context), I discovered the following function (port + comments by me):dart int fastFloor(double x) { // We cannot simply return x.toInt() because casting to an integer floors // towards zero (truncates) and we want to floor towards negative infinity. final xi = x.toInt(); return x < xi ? xi - 1 : xi; }PerformanceThe name "fastFloor" surprised me - I thought: this cannot be faster than double.floor, right?So, I ran some benchmarks and I discovered:**fastFloor is about 20% faster than floor** (tested for values between -10000000 and 10000000 on macOS)IssueI have opened an issue about it here: https://github.com/dart-lang/sdk/issues/46650DiscussionMy question is: why is that the case? Does anyone have an idea why this could be?

Currently porting KdotJPG's OpenSimplex2 to #Dart to be able to use it in my funvas animations in #Flutter 🚀 Using @etiennejcb's very basic (and totally amazing) noise propagation sample to validate the implementation ✨ Looking good so far 💯

State Management With Timers
So I have a few scenarios that I'm curious how experienced devs would approach. The premise is simple: I have multiple widgets who's display depend on a timer. For example, a text widget that counts the seconds of current time, like a digital clock. What would be the most efficient approach?An ancestor widget that calls setState each second the timer runs its callback. Note that there could be widgets in between this ancestor and the widgets that need the state change value. Usually we try to push those changes to the leaves.Keep the state in the widgets that need the value, which would be the closest ancestor to the text widget in my example. This would mean creating a timer for each of these widgets. I would guess that the timers could be out of sync due to this approach, and build calls might be spread out across multiple frames. That's ok, but would that cause more jank than approach 1Use something like the provider package and wrap the widgets that need the state in Consumers.I'm largely curious about scenarios 1 and 2 - just to see how someone would approach that without breaking out a package or Inherited widgets.
