The plugin don't work on iPhone browser

I build a webApp and tested on iPhone browser doesn't work.
Model iPhone 14
iOS version: 17.5

camera view too small in mobile browser

Support for MacOS

Hi, can you support scanning on MacOS?

Please add Camera Zoom feature for iOS barcode scanner

Currently, android camera has zoom functionality for scanning barcodes at longer distance, if you provide same zoom functionality for iOS that would be great..

Grey screen on android 14

I'm facing a issue on android 14.
When SimpleBarcodeScannerPage is instantiated return a grey frame in place of a camera view.

On all other android versions and on ios it's working fine.

Any suggestion or fixes?

Scan QR Codes from Photo Library

• access photos from the photo library to scan QR code from a photo

Camera wont connect

Hello!

I am really struggling to implement this into a project. All I am getting is a grey blank page when I click the button.

I am currently looking for this to work as a barcode & qr code scanner for web on desktop and mobile.

This is the code.

import 'package:simple_barcode_scanner/screens/shared.dart';

import 'package:simple_barcode_scanner/simple_barcode_scanner.dart';

class SimpleBcodeScanner extends StatefulWidget {
const SimpleBcodeScanner({
Key? key,
this.width,
this.height,
}) : super(key: key);

final double? width;
final double? height;

@OverRide
_SimpleBcodeScannerState createState() => _SimpleBcodeScannerState();
}

class _SimpleBcodeScannerState extends State {
String result = '';
@OverRide
Widget build(BuildContext context) {
return Center(
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
ElevatedButton(
onPressed: () async {
var res = await Navigator.push(
context,
MaterialPageRoute(
builder: (context) => const SimpleBarcodeScannerPage(),
));
setState(() {
if (res is String) {
result = res;
}
});
},
child: const Text('Open Scanner'),
),
Text('Barcode Result: $result'),
],
),
);
}
}

Barcode Scan incorrect

I have the same issue that in the below link
Did it fix at this package?
AmolGangadhare/flutter_barcode_scanner#301

how to scan in windows?

Hi.
I want to try using this package in windows.
--Is it possible for this package to use webcam of laptop to scan bar code?
--and is it possible for this package to scan barcode with a barcode reader device?
when I run the code, after allowing camera access, nothing happens.
this is what I use:

ElevatedButton(
                                onPressed: () async {
                                  var res = await Navigator.push(
                                      context,
                                      MaterialPageRoute(
                                        builder: (context) =>
                                            const SimpleBarcodeScannerPage(),
                                      ));
                                  if (!mounted) return;
                                  res != null
                                      ? BlocProvider.of<--->(context)
                                          .selectedFileCode(res as String)
                                      : null;
                                },
                                child: const Text('Open Scanner'),
                              ),

Can we have an option to select Front Camera as default camera?

default camera option must be there

Windows : After QR code scanning is complete the Microsoft edge Webview2 process stays active and takes up lots of CPU resources.

Building for flutter windows throws errors

I added this package to the project and tried to build for windows and it throwed the errors as shown in the attched image. How can I resolve this? I tried to run the sample code and it gave the same set of errors too.

Add Cancel or back Button to Windows Barcode scanner

Currently, there is no back button or cancel button is not there in windows barcode scanner and it is very difficult for the user if user does not want to scan and go back.

Inline script in barcode.html require csp 'unsafe-inline' in the script-src directive

The unsafe-inline keyword annuls most of the security benefits that Content-Security-Policy provide.
It'd be better if you created a new javascript file with the inline script that you inserted into barcode.html file and then point to the external script file through the src attribute.

Using main camera for scan in web

Somehow when using scanner on web, the wide camera in being used instead of main camera.
Is there any way to use main camera?!

Select front camera as default in the barcode scanner

As a developer, I want to make the front camera the default one.

Open scanner in dialog instead of a separate page (optional)

can not scan

Hi,
I want to scan some qrCode in android, I get these messages in console and scanner is not returning anything .
I tried on android 4 and 12

W/DynamiteModule(30647): Local module descriptor class for com.google.android.gms.vision.dynamite.barcode not found.
I/DynamiteModule(30647): Considering local module com.google.android.gms.vision.dynamite.barcode:0 and remote module com.google.android.gms.vision.dynamite.barcode:0

I'm calling barcode scanner like this:

 ElevatedButton(
                                onPressed: () async {
                                  var res = await Navigator.push(
                                      context,
                                      MaterialPageRoute(
                                        builder: (context) =>
                                            const SimpleBarcodeScannerPage(
                                              scanType: ScanType.qr,
                                            ),
                                      ));
                                  setState(() {
                                    if (res is String) {
                                      _serialNumber = res;
                                    }
                                  });
                                },
                                child: Text('scan')),

Web Scanner works differently

The scanner available for android, ios is good, but for web its only able to scan CODE 128 barcode, and most formats are being ignored by the web scanner.
Unable to scan EAN13, UPCA, etc.

Testing this barcode, EAN-13: Barcode product Link

Android: Scans perfectly

Web: Ignores and unable to detect EAN-13 type Barcode,
However html5-qrcode says they support ean13 as well.

Make the scan area of on Windows more larger

Currently, the scan area on windows only suitable for barcode. Can you make it square when we change scanType to ScanType.qr?

Simple barcode scanner doesn't use the main camera in web mobile

I'm using the simple_barcode_scanner demo, and in the web version on an android phone, it uses the low resolution macro camera rather than the main camera. I have to get really close to the barcode, and since it is so low in resolution, it can't scan barcode well especially barcode on a screen rather than on a physical object.

After making signed apk apk stop working

After adding any barcode scanning library, my app stop working on android devices, it working fine while in debug mode but when I create signed apk and install on Android device app only shows white screen, nothing else, please suggest what should I do.

Flutter package - simple_barcode_scanner 0.0.5 not working on windows

Hi I am currently using the flutter package simple_barcode_scanner 0.0.5 in order to scan a QR code on my (flutter) windows application. The project compiles, camera permission is requested etc, however I am not receiving any result back when scanning a QR code. Can someone kindly confirm if they are experiencing the same result and/or if there is an additional setup/configuration step that I might be missing in order for this package to work.

Kind regards,
Alecia

QR code not scanning for window

Hi the camera opens up on my desktop app but nothing happens when I put a barcode in front of it, however when I create the app for Android it works fine. Could you help?

I don't mind paying for your time

Thanks

Windows: Opens camera but doesn't read QR Codes.

Good Day, I am working on a desktop application that scans a QR Code using your plugin. The camera launches but it doesn't give any results. Nothing happens, the camera just opens. I was wondering how to solve this.

The application closes when trying to start the barcode scanner

It's happening that my application is closing when I call the barcode scanning. The system is giving me the error below:

Enhancement for barcode scan

• The window for the barcode is a little small. so I have to put the barcode far from the camera and it's hard to see that.

• Every time I press the button to scan a barcode, it asks for camera permission. It would be better to remember the choice and not ask every time.

Feature request: make page title an optional parameter to BarcodeScanner

@tashi146 simple feature request to make page title an optional parameter to BarcodeScanner(). I can do a pull request if you want, but it's a really trivial change, might be more efficient if you make the change. I'm only using web but it probably applies to other platforms too.

For web:
In https://github.com/CodingWithTashi/simple_barcode_scanner/blob/main/lib/screens/web.dart add a new param to BarcodeScanner to allow override of the default page title.

just add

final String? pageTitle; 

and then

appBar: AppBar(
        title: Text(pageTitle?? kScanPageTitle),
      ),

Change appbar color web

simple_barcode_scanner wont scan

hi
i downloaded the dependencie and followed the instructions as said in the documentation , but in my web version of the flutter app the barcode scanner just open the camera and stay there , i didn't really get the html5 qr code part , do i need to install a new package to get barcode to scan in web?

Mobile web not working

Hi, my friend
scanner not work on mobile web (chrome) :(
The white screen opens and the camera does not activate, While it works properly in Windows browser (chrome) !

Delay the scanning

Hi, is that possible to delay the scanning? Like i dont want the to scan immediately after the function is call. Instead, i want it to wait for few second for the end user to hold for the right position, otherwise it the possibility of scanning wrong barcode in bunch of barcode is very high.

The window for the barcode is a little small. so I have to put the barcode far from the camera and it's hard to see that.

No change scanType

no change rectangular type to squares

When I use QR containing English Text: There is no issue.
