Use the AlertStyle class to customize.

      animationType: AnimationType.fromTop,
      isCloseButton: false,
      isOverlayTapDismiss: false,
      descStyle: TextStyle(fontWeight: FontWeight.bold),
      animationDuration: Duration(milliseconds: 400),
      alertBorder: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(0.0),
        side: BorderSide(
          color: Colors.grey,
        ),
      ),
      titleStyle: TextStyle(
        color: Colors.red,
