## Supported Barcode Formats | 1D product | 1D industrial | 2D | ---------- | ----------------- | -------------- | UPC-A | Code 39 | QR Code | UPC-E | Code 93 | DataMatrix | EAN-8 | Code 128 | Aztec | EAN-13 | Codabar | PDF417 | DataBar | ITF | MaxiCode (beta) | | DataBar Expanded | ## Features - Scan barcode from camera stream - Scan barcode from image path or url - Create barcode from text - Flashlight and pinch to zoom support ## Todo - Read multiple barcodes from camera or gallery - Return scanned barcode position and size - Write tests ## Getting Started ### To read barcode: ```dart import 'package:flutter_zxing/flutter_zxing.dart'; // Use ReaderWidget to quickly read barcode from camera image @override Widget build(BuildContext context) { return Scaffold( body: ReaderWidget( onScan: (result) async { // Do something with the result }, ), ), ); // Or use FlutterZxing // To read barcode from camera image directly await FlutterZxing.startCameraProcessing(); // Call this in initState cameraController?.startImageStream((image) async { CodeResult result = await FlutterZxing.processCameraImage(image); if (result.isValidBool) { debugPrint(result.textString); } return null; }); FlutterZxing.stopCameraProcessing(); // Call this in dispose // To read barcode from XFile, String or url XFile xFile = XFile('Your image path'); CodeResult? resultFromXFile = await FlutterZxing.readImagePath(xFile); String path = 'Your image path'; CodeResult? resultFromPath = await FlutterZxing.readImagePathString(path); String url = 'Your image url'; CodeResult? resultFromUrl = await FlutterZxing.readImageUrl(url); ``` ### To create barcode: ```dart import 'package:flutter_zxing/flutter_zxing.dart'; import 'dart:typed_data'; import 'package:image/image.dart' as imglib; // Use WriterWidget to quickly create barcode @override Widget build(BuildContext context) { return Scaffold( body: WriterWidget( onSuccess: (result, bytes) { // Do something with the result }, onError: (error) { // Do something with the error }, ), ), ); // Or use FlutterZxing to create barcode directly final text = 'Text to encode'; final result = FlutterZxing.encodeBarcode(text, 300, 300, Format.QRCode, 10, 0); if (result.isValidBool) { final img = imglib.Image.fromBytes(width, height, result.bytes); final encodedBytes = Uint8List.fromList(imglib.encodeJpg(img)); // use encodedBytes as you wish } ``` ## License MIT License.
