hi can we return instead of code (future) to return object which contain the code and type (if its QR or Bar..) and if its barcode to return barcode type (pdf,code128 etc)...

static Future scan({Configuration config}) async => await _channel.invokeMethod('scan', config?.writeToBuffer());

[devtronic]

@kw2019ltd Of course 🙂

Will 3.x support the following feature ?

var config = Configuration();
config.cancelText = "Abbrechen"; // Your text for the iOS cancel button 
config.flashOnText = "Blitz an"; // Your text for the Flash On Button
config.flashOffText = "Blitz aus"; // Your text for the Flash Off button
config.restrictFormat.addAll([BarcodeFormat.qr]); // Only scan qr codes

// Camera index. Get it from [BarcodeScanner.numberOfCameras]
config.useCamera = 1;
String barcode = await BarcodeScanner.scan(config: config);

@ihihihihihihih It's 9:21 AM in Germany, I'll update the update the library today 😉

@kw2019ltd afaik are this types only supported by the iOS scanner library. IMO the package only should provide options which are supported by both platforms iOS and Android.

[kw2019ltd]

good, yes those format are supported by firebase_ml_vision (flutter plugin) for both android and ios.

@kw2019ltd Unfortunately this lib doesn’t use firebase_ml_vision, but me.dm7.barcodescanner:zxing for android.

[devtronic]

@sclausen Yes, but I plan to migrate to ML vision since it provides for both iOS and Android the same options.

[sclausen]

Wouldn’t that force developers to have a firebase account for their project to use this library? This seems to be a severe change.

3.0.0-dev.2 has a problem on my Android phone.

The plugin on debug mode is ok.

But on release mode has the following error.
