After Scanning Barcode , how to pass scanned data to a new page? - flutter

Question

the thing I will like to ask about is that I want to pass the data in the barcode to a new page after scanning. Is there anyway can I do it?
Hope anyone can solve my problem <3
Had been doing this for my intern for 4 days and I have no clue at all. Hope can solve it as fast as possible
Below is my code:
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:flutter_svg/flutter_svg.dart';
import 'package:meditation_app/widgets/category_card.dart';
import 'package:flutter_barcode_scanner/flutter_barcode_scanner.dart';
class HomeScreen extends StatefulWidget {
const HomeScreen({Key key}) : super(key: key);
#override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
String _scanBarcode = 'Unknown';
#override
void initState() {
super.initState();
}
Future<void> scanBarcodeNormal() async {
String barcodeScanRes ;
try {
barcodeScanRes = await FlutterBarcodeScanner.scanBarcode(
'#ff6666', 'Cancel', true, ScanMode.BARCODE);
print(barcodeScanRes);
} on PlatformException {
barcodeScanRes = 'Failed to get platform version.';
}
if (!mounted) return;
setState(() {
_scanBarcode = barcodeScanRes; //Here is the thing I will like to pass to another page
});
}
#override
Widget build(BuildContext context) {
var size = MediaQuery.of(context).size;
return Scaffold(
appBar: AppBar(
centerTitle: true,
title: const Text('EzyMerchant'),
actions: <Widget>[
IconButton(
icon: SvgPicture.asset("assets/icons/setting.svg",color: Colors.white,),
onPressed: () {
Navigator.pushNamed(context, '/setting');
},
),
],
),
body: Stack(
children: <Widget>[
SafeArea(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical:20),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
"Good Morning \nAdmin",
style: Theme.of(context)
.textTheme
.headline4
.copyWith(fontWeight: FontWeight.w900),
),
SizedBox(height: 50),
Expanded(
child: Container(
child: GridView.count(
crossAxisCount: 2,
childAspectRatio: .85,
crossAxisSpacing: 20,
mainAxisSpacing: 20,
children: <Widget>[
Container(
child: CategoryCard(
title: "Add",
svgSrc: ("assets/icons/Hamburger.svg"),
press: () => scanBarcodeNormal(), //Here is the scan function
),
),
CategoryCard(
title: "Redeem",
svgSrc: "assets/icons/Excrecises.svg",
press: () {},
),
CategoryCard(
title: "Wallet",
svgSrc: "assets/icons/Meditation.svg",
press: () {},
),
CategoryCard(
title: "Voucher",
svgSrc: "assets/icons/yoga.svg",
press: () {},
),
],
),
),
),
],
),
),
)
],
),
);
}
}

You can use arguments property in Navigator.pushNamed like
Navigator.pushNamed(context, '/setting',arguments: _scanBarcode);
