                    const CircleAvatar(
                      radius: 50,
                    ),
                    Container(
                      color: Colors.yellowAccent,

try this:

CircleAvatar(
  backgroundColor: Colors.yellow,
  radius: 100,
  child: Container(
    alignment: Alignment.bottomCenter,
    clipBehavior: Clip.antiAlias,
    decoration: BoxDecoration(shape: BoxShape.circle),
    child: Container(
      height: 40,
      width: double.infinity,
      color: Colors.red,
    ),
  ),
)
