Error when upgrade Flutter and SDK

[ikwijaya]

thanks for awesome plugin.

i have some error, after upgrade flutter . this is my version Flutter 0.10.2 • channel beta • https://github.com/flutter/flutter.git Framework • revision d8cbb80206 (7 weeks ago) • 2018-10-26 01:30:21 -0400 Engine • revision 6c2ade9fa2 Tools • Dart 2.1.0-dev.8.0.flutter-bf26f760b1

and this is my code Future _scanQR() async { print('func scanQR ==> access scan qr 2'); try { print(' try ==> '); String _qrscan = await BarcodeScanner.scan(); Map _map = json.decode(_qrscan); print('scan => '+ _qrscan); } on PlatformException catch (e){ print(' PlatformException ==> '+ e.toString()); if(e.code == BarcodeScanner.CameraAccessDenied){ // Navigator.pushNamed(context, '/dashboard'); toast.show( context: context, message: "Camera Permission is access denied.", status: "error", duration: new Duration(seconds: 3), position: new Offset(15.0, 100.0), ); } else { // Navigator.pushNamed(context, '/dashboard'); toast.show( context: context, message: "Unknown error: $e", status: "error", duration: new Duration(seconds: 3), position: new Offset(15.0, 100.0), ); } } on PlatformException { print(' PlatformException ==> '); // Navigator.pushNamed(context, '/dashboard'); toast.show( context: context, message: 'null (User returned using the "back"-button before scanning anything. Result)', status: "error", duration: new Duration(seconds: 3), position: new Offset(15.0, 100.0), ); } catch (e) { // Navigator.pushNamed(context, '/dashboard'); print(' Catch ==> '); print('Error : $e'); toast.show( context: context, message: 'Error : $e', status: "error", duration: new Duration(seconds: 3), position: new Offset(15.0, 100.0), ); } }

my problem is => code String _qrscan = await BarcodeScanner.scan(); cannot read my qrcode without any error prompted.

I think I have a similar issue too.

I'm using barcode_scan : "0.0.4"

and I get the following error

The current Dart SDK version is 2.1.0-dev.9.4.flutter-f9ebf21297.

Because flutter_barcode depends on barcode_scan >=0.0.2 <0.0.5 which requires SDK version <2.0.0, version solving failed.

Looks like Dart > v2.0.0 is not supported by this package.
