QRCode Reader plugin for Flutter #

A Flutter plugin for reading QR Codes with the camera.

Example #

import 'package:qrcode_reader/QRCodeReader.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
               .scan();

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