• 🎯 Vector Sharpness: Rendered as vector paths inside PDFs for crisp 100% scanning reliability.
• 🔗 Dynamic Data Interpolation: Bind dynamic barcodes to runtime data variables ({{shipment.tracking_code}}).

💻 Human-Centric Usage Examples

Rendering a Shipping Label Barcode in PDF

Here is how human developers register and define a shipping label barcode inside a PDF template:

import 'package:pdfcraft_core/pdfcraft_core.dart';
import 'package:pdfcraft_generator/pdfcraft_generator.dart';
import 'package:pdfcraft_barcode/pdfcraft_barcode.dart';

void main() {
  // 1. Register BarcodeRenderer into GeneratorRegistry
  GeneratorRegistry.instance.register(BarcodeRenderer());

  // 2. Add a barcode field schema to your template page
  final barcodeField = FieldSchema(
    id: 'tracking_barcode',
    type: 'barcode',
    bounds: const RectBounds(x: 50, y: 200, width: 300, height: 80),
    properties: {
      'data': 'TRACK-987654321-US',
      'symbology': 'code128',
      'showText': true,
      'barColor': '#000000',
    },
  );

  print('Barcode plugin registered and configured for field: ${barcodeField.id}');
}
