QRCode Reader plugin for Flutter

This is a copy of qrcode_reader with build fix

The original repo is archived so publishing as a new plugin

Flutter plugin for reading QR Codes with the camera.


  qr_reader: ^0.1.3


import 'package:qr_reader/qr_reader.dart';
Future<String> futureString = new QRCodeReader()
               .setAutoFocusIntervalInMs(200) // default 5000
               .setForceAutoFocus(true) // default false
               .setTorchEnabled(true) // default false
               .setHandlePermissions(true) // default true
               .setExecuteAfterPermissionGranted(true) // default true

These options are Android only, this is the simplest way of plugin usage:

Future<String> futureString = new QRCodeReader().scan();
