Barcode Reader API - Dart/Flutter Client

Barcode Reader decodes 1D barcodes from an uploaded image or an image URL, including EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Code 93, ITF, Codabar and GS1 DataBar. It returns the decoded value and the symbology. Paid plans add the GTIN, the barcode's orientation and corners, and every barcode found in the image.

This is the Dart/Flutter client for the Barcode Reader API.

Installation

Add this to your pubspec.yaml:

dependencies:
  apiverve_barcodereader: ^1.2.2

Then run:

dart pub get
# or for Flutter
flutter pub get

Usage

import 'package:apiverve_barcodereader/apiverve_barcodereader.dart';

void main() async {
  final client = BarcodereaderClient('YOUR_API_KEY');

  try {
    // This API requires a file upload — a JSON body is rejected with a 400.
    final response = await client.executeWithFile('/path/to/your-file');

    print('Status: ${response.status}');
    print('Data: ${response.data}');
  } catch (e) {
    print('Error: $e');
  }
}
