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.

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();

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

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

Suggestions

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Fix analysis and formatting issues.

    Analysis or formatting checks reported 1 hint.

    Run flutter format to format lib/qr_reader.dart.
