For what it's worth, there's a potential fix for the crash in SmoothProductCarousel:

@override
void didChangeDependencies() {
  super.didChangeDependencies();
  final ContinuousScanModel model = context.watch<ContinuousScanModel>();
  setState(() {
    barcodes = model.getBarcodes();
  });
  if (_controller.ready) { // that's the fix
    _controller.animateToPage(barcodes.length - 1 + _searchCardAdjustment);
  }
}

With that, no crash.
Will the animation take place eventually: I don't know.
Unfortunately I cannot really test that because 1. my smartphone is too old to use https queries (at least with smoothie) and 2. with the emulators I haven't tested how to scan (and anyway my computer is already slow enough).
