Save Generated Barcodes

The Aspose.BarCode Cloud SDK for Dart by the GenerateApi provides methods to generate barcodes to the Uint8List. Then you can work with result in order to obtain the desired outcomes. This API supports various barcode formats and configurations, enabling users to customize barcode generation to fit their needs.

Methods

  • generate: Generates a barcode via GET request.
  • generateBody: Generates a barcode via POST request with JSON or XML body.
  • generateMultipart: Generates a barcode via POST request with multipart form data. All of these methods return a Uint8List.

Saving the Barcode to File

Below are examples demonstrating how to save the generated barcode stream to a file.

Example: Using generate

import 'dart:io';
import 'dart:typed_data';
import 'package:aspose_barcode_cloud/aspose_barcode_cloud.dart';

Configuration makeConfiguration() {
  final envToken = Platform.environment['TEST_CONFIGURATION_ACCESS_TOKEN'];
  if (envToken != null) {
    return Configuration(accessToken: envToken);
  } else {
    return Configuration(
      clientId: "Client Id from https://dashboard.aspose.cloud/applications",
      clientSecret:
          "Client Secret from https://dashboard.aspose.cloud/applications",
    );
  }
}

Future<void> main() async {
  final configuration = makeConfiguration();
  final apiClient = ApiClient(configuration);
  final generateApi = GenerateApi(apiClient);

  final fileName =
      "${Directory.current.path}${Platform.pathSeparator}Code128.jpeg";

  final Uint8List response = await generateApi.generate(
      EncodeBarcodeType.Code128, "Aspose.BarCode.Cloud");

  final file = File(fileName);
  file.writeAsBytes(response);

  print("File '${file.path}' generated.");
}

Example: Using generateBody

import 'dart:io';
import 'dart:typed_data';

import 'package:aspose_barcode_cloud/aspose_barcode_cloud.dart';

Configuration makeConfiguration() {
  final envToken = Platform.environment['TEST_CONFIGURATION_ACCESS_TOKEN'];
  if (envToken != null) {
    return Configuration(accessToken: envToken);
  } else {
    return Configuration(
      clientId: "Client Id from https://dashboard.aspose.cloud/applications",
      clientSecret:
          "Client Secret from https://dashboard.aspose.cloud/applications",
    );
  }
}

Future<void> main() async {
  final fileName =
      "${Directory.current.path}${Platform.pathSeparator}Pdf417.png";

  final configuration = makeConfiguration();
  final apiClient = ApiClient(configuration);
  final generateApi = GenerateApi(apiClient);

  final generateParams = GenerateParams(
    EncodeBarcodeType.Pdf417,
    EncodeData("Aspose.BarCode.Cloud", EncodeDataType.StringData),
    BarcodeImageParams()
      ..foregroundColor = "#FF5733"
      ..backgroundColor = "#FFFFFF"
      ..imageFormat = BarcodeImageFormat.Jpeg,
  );

  final Uint8List response = await generateApi.generateBody(generateParams);

  final file = File(fileName);
  file.writeAsBytes(response);

  print("File '${file.path}' generated.");
}

Example: Using generateMultipart

import 'dart:io';
import 'dart:typed_data';

import 'package:aspose_barcode_cloud/aspose_barcode_cloud.dart';

Configuration makeConfiguration() {
  final envToken = Platform.environment['TEST_CONFIGURATION_ACCESS_TOKEN'];
  if (envToken != null) {
    return Configuration(accessToken: envToken);
  } else {
    return Configuration(
      clientId: "Client Id from https://dashboard.aspose.cloud/applications",
      clientSecret:
          "Client Secret from https://dashboard.aspose.cloud/applications",
    );
  }
}

Future<void> main() async {
  final fileName =
      "${Directory.current.path}${Platform.pathSeparator}Pdf417.png";
  final configuration = makeConfiguration();
  final apiClient = ApiClient(configuration);
  final generateApi = GenerateApi(apiClient);

  final Uint8List response = await generateApi.generateMultipart(
      EncodeBarcodeType.Pdf417, "Aspose.BarCode.Cloud");

  final file = File(fileName);
  file.writeAsBytes(response);

  print("File '${file.path}' generated.");
