Installation

Install the latest version from pub.

Getting started

Import the following package.

import 'package:syncfusion_flutter_barcodes/barcodes.dart';

Add Barcode Generator to the widget tree

Add the Barcode Generator widget as a child of any widget. Here, the widget is added as a child of the container widget and the height to the container is specified (otherwise it will take full container height)

 @override
    Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: Center(
              child: Container(
        height: 200,
        child: SfBarcodeGenerator(value: 'www.syncfusion.com'),
      ))),
    );
  }

Add barcode symbology

Set the required symbology type to the barcode generator based on input value by initializing the symbology property. In the following code snippet, the QR code is set as the barcode symbology.

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: Center(
              child: Container(
        height: 200,
        child: SfBarcodeGenerator(
          value: 'www.syncfusion.com',
          symbology: QRCode(),
        ),
      ))),
    );
  }

Show value of the barcode

input values can be displayed by enabling the showValue property of barcodes.

  @override
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: Center(
              child: Container(
        height: 200,
        child: SfBarcodeGenerator(
          value: 'www.syncfusion.com',
          symbology: QRCode(),
          showValue: true,
        ),
      ))),
    );
  }

The following screenshot illustrates the result of the previous code sample.
