fxTick method
void
fxTick()
The probed frame-aligned flush (500 writes → 1 rebuild): coalesce all fx writes of a batch into one notification, through whatever sceneFlushScheduler the process installed.
Implementation
void fxTick() {
if (_fxScheduled) return;
_fxScheduled = true;
sceneFlushScheduler(() {
_fxScheduled = false;
notifyListeners();
});
}
