      title: Text(title),
      content: Text(body),
      actions: [
        CupertinoDialogAction(
          isDefaultAction: true,
          child: Text('Ok'),
          onPressed: () async {
            Navigator.of(context, rootNavigator: true).pop();
            await Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => SecondScreen(payload),
              ),
            );
          },
        )
