Or you can use RFlutter Alert library for that. It is easily customizable and easy-to-use. Its default style includes rounded corners and you can add buttons as much as you want.

Alert Style:

var alertStyle = AlertStyle(
    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,
    ),
);

And assing your AlertStyle object to Alert's style field.

Alert(
    context: context,
    style: alertStyle,
    type: AlertType.info,
    title: "RFLUTTER ALERT",
    desc: "Flutter is more awesome with RFlutter Alert.",
    buttons: [
    DialogButton(
        child: Text(
        "COOL",
        style: TextStyle(color: Colors.white, fontSize: 20),
        ),
        onPressed: () => Navigator.pop(context),
        color: Color.fromRGBO(0, 179, 134, 1.0),
        radius: BorderRadius.circular(0.0),
    ),
    ],
).show();
