raw_scanner #
A simplified barcode scanner.
Hecho en Puerto Rico 🇵🇷 por Radamés J. Valentín Reyes
What is this? #
A package to scan barcodes(QR codes and others) in a simplified manner. It's a wrapper around tools rather than a personal project coded from scratch.
Why did I make it? #
Simplified flutter packages for scanning QR codes that I could find didn't work, the others were too time consuming to get them to work, so I took the best among them and tried to simplify it.
Importing the package #
import 'package:raw_scanner/raw_scanner.dart';
Use #
Note: "RawScanner" is the object that contains all of the methods. #
The example below returns a Widget containing a QR code
RawScanner.generateQrCode("A string for the QR here")
The example below scans for the specified "typeOfCode" and returns it as a String. Take into account that the returned value may be null.
String scanResults = await RawScanner.scanCode(
typeOfCode: BarcodeFormat.qrcode,
context: context,
foregroundColor: Colors.red,
);
Full example #
import 'package:flutter/material.dart';
import 'package:qr_code_scanner/qr_code_scanner.dart';
import 'package:raw_scanner/raw_scanner.dart';
void main() => runApp(Runner());
class Runner extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Test(),
);
}
}
class Test extends StatefulWidget {
@override
_TestState createState() => _TestState();
}
class _TestState extends State<Test> {
String scanResults = "";
@override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
TextButton(
onPressed: ()async{
scanResults = await RawScanner.scanCode(
typeOfCode: BarcodeFormat.qrcode,
context: context,
foregroundColor: Colors.red,
);
print(scanResults);
setState(() {
scanResults = scanResults;
});
},
child: Text(
"Scan",
),
),
RawScanner.generateQrCode(scanResults)
],
),
),
);
}
}
