## 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, image path or url - Scan multiple barcodes from camera stream, image path or url - Create barcode from text - Return scanned barcode position points - Flashlight and pinch to zoom support ## Todo - 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 flutter_zxing plugin methods // To read barcode from camera image directly await zx.startCameraProcessing(); // Call this in initState cameraController?.startImageStream((image) async { Code result = await zx.processCameraImage(image); if (result.isValid) { debugPrint(result.text); } return null; }); zx.stopCameraProcessing(); // Call this in dispose // To read barcode from XFile, String, url or Uint8List bytes XFile xFile = XFile('Your image path'); Code? resultFromXFile = await zx.readBarcodeImagePath(xFile); String path = 'Your local image path'; Code? resultFromPath = await zx.readBarcodeImagePathString(path); String url = 'Your remote image url'; Code? resultFromUrl = await zx.readBarcodeImageUrl(url); Uint8List bytes = Uint8List.fromList(yourImageBytes); Code? resultFromBytes = await zx.readBarcode(bytes); ``` ### 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 result = zx.encodeBarcode( 'Text to encode', format: Format.QRCode, width: 120, height: 120, margin: 10, eccLevel: 0, ); if (result.isValid) { final img = imglib.Image.fromBytes(width, height, result.bytes); final encodedBytes = Uint8List.fromList(imglib.encodeJpg(img)); // use encodedBytes as you wish } ``` ## License MIT License.
