zxing-flutter #

this plugin is a simple wrapper of swiftScan for ios and zxing-android-embedded for android.

Getting Started #

Currently isBeep parameters and isContinuous parameters are only valid on the android platform.



  • Implement isContinuous parameters on ios platform.
  • The swiftScan library is replaced with the system API.
  • plugin returns a list of string rather than single string.


  • return List<String> instead of List.


import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:zxing/zxing.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => new _MyAppState();

class _MyAppState extends State<MyApp> {
  List<String> _barcodeList = List()..add("Unknow");

  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text('Zxing-flutter example app'),
        body: new Center(
          child: new Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              new Text('barcode: $_barcodeList\n'),
              new RaisedButton(
                onPressed: () {
                  try {
                    Zxing.scan(isBeep: false, isContinuous: false).then(
                      (resultList) {
                        print("client scan result:" + resultList?.toString());
                          () {
                            _barcodeList = resultList;
                  } on PlatformException {
                    _barcodeList = List()..add('Failed to get barcode.');
                child: Text('scan'),
