  @override
  Widget build(BuildContext context) {
    return CustomScrollView(
      slivers: [
        for (var color in colors)
          SliverPadding(
            padding: MediaQuery.of(context).padding,
            sliver: SliverCard(
              color: color,
              margin: const EdgeInsets.symmetric(
                horizontal: 16.0,
                vertical: 2.0,
              ),
              sliver: SliverPadding(

                sliver: SliverToBoxAdapter(
                  child: Text('#${(color.value & 0xFFFFFF).toRadixString(16)}'),
                ),
