can someone explain to me why 1 positional argument expected but 0 found - flutter

Question

I am new to Flutter. I'm trying to make another alert dialog window after I click Yes on first alert dialog, but there is an error. The error was at my showSecond(); The outcome somehow will be like this. It would be a pleasure if someone can explain to me ;( and show me the right one. Thank you so much!
This is my code.
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:smart_parking/features/home/homescreen.dart';
class MyBottomBar extends StatelessWidget {
const MyBottomBar({ Key? key }) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
height: 50,
width: double.maxFinite,
decoration: BoxDecoration(
color: Colors.grey.shade200
),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget> [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('Total payment', style: TextStyle( fontSize: 15, decoration: TextDecoration.none, color: Colors.grey.shade800)),
SizedBox(height: 5),
Text('RM 46.00', style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 10, decoration: TextDecoration.none),)
],
),
SizedBox( width: 90),
Image.asset('boxP.png', height: 30, width: 50),
Spacer(),
Column(
children: [
Container( height: 50, width: 150, color: Colors.black,
child: Align(
alignment: Alignment.center,
child: TextButton(child: Text('PAY', style: TextStyle(color: Colors.white)),
onPressed: () {
showAlertDialog(context);
},),
),
)
],
),
]
),
);
}
}
void showAlertDialog(BuildContext context) {
showDialog(context: context,
builder: (BuildContext context)
{ return CupertinoAlertDialog(
title: Text("Payment Confirmation", style: TextStyle( fontWeight: FontWeight.bold),),
content: Text("Are you sure with your payment?"),
actions: [
CupertinoDialogAction(child: Text('Cancel'),
onPressed: () { Navigator.of(context).pop();
}
),
CupertinoDialogAction
(child: Text("Yes"),
onPressed: () {
Navigator.push(context,
MaterialPageRoute(builder: (context) => const HomeScreen()));
showSecond();
},
)
],
);
}, );
}
void showSecond( BuildContext context) {
showDialog(
context: context,
builder: (BuildContext context) => AlertDialog(
title: Text("Thank you for paying with us"),
content: Icon(Icons.check_circle_outline),
actions: [
TextButton(
onPressed: () {
Navigator.of(context).pop();
},
child: const Text('Okay'),
),
],
),
);
}
