List<Color> colors = [Colors.blue];

//...

ReorderableCarousel(
  numItems: colors.length,
  addItemAt: (index) {
    setState(() {
      colors.insert(
          index,
          Color((Random().nextDouble() * 0xFFFFFF).toInt())
              .withOpacity(1.0));
    });
  },
  itemBuilder: (boxSize, index, isSelected) {
    return AnimatedContainer(
      key: ValueKey(colors[index]),
      duration: const Duration(milliseconds: 250),
      height: 150,
      width: boxSize,
      decoration: BoxDecoration(
        border: isSelected
          ? Border.all(color: Colors.amber, width: 10.0)
          : null,
        color: colors[index],
      ),
    );
  },
  onReorder: (oldIndex, newIndex) {
    // items have be reordered, update our list
    setState(() {
      Color swap = colors.removeAt(oldIndex);
      colors.insert(newIndex, swap);
    });
  },
  onItemSelected: (int selectedIndex) {
    // a new item has been selected
    setState(() {
      selectedColor = colors[selectedIndex];
    });
