You can try with this code:

    Path path = Path();
    path.moveTo(avatarRoot!.width / 2, 0);
    path.cubicTo(
        avatarRoot!.width / 2,
        0,
        avatarRoot!.width / 2,
        padding!.top   avatarChild!.height / 2,
        avatarRoot!.width,
        padding!.top   avatarChild!.height / 2);
    canvas.drawPath(path, _paint!);

You will need learn to use cubicTo function
