Answer 1

Whenever you use BoxDecoration() remember to put the color parameter inside the BoxDecoration().

child: Container(
  decoration: BoxDecoration(
  borderRadius: BorderRadius.circular(10), // <= No more error here :)
  color: Colors.red,
  ),
  height: 100,
  child: Text(listTmp[index]),
  ),
);
