Compare DOC in Dart

Our Dart/Flutter SDK is designed to give you the most accurate result, even though comparison is a complex function itself.

Sometimes you need to be sure that the document in the DOC format has not been changed, and if it has, you need to find out what the difference is. Just use our Dart/Flutter diff tool to compare two DOC files and find differences in whole words or single characters. Moreover, if only one character in a word has changed, this word will be marked as changed entirely.

Now you no longer need to spend time manually comparing DOC documents, and you can quickly find even small changes and export such diffs to a document in a convenient format.

Try to compare DOC documents

Check out how our solution to compare DOC files using Dart/Flutter SDK works. To achieve this, load the DOC files you want to compare and select the export file format – it will be automatically loaded after comparing.

Note that you need to accept all revisions in compared documents before calling the comparison method, as shown in our example:

Compare DOC files using Dart and find the difference

Input files

Upload the compared file

Run code

Upload the second file to compare

Output format

Select the target format from the list

import 'package:aspose_words_cloud/aspose_words_cloud.dart';

final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);

final fileName1 = 'Input1.doc';
final fileName2 = 'Input2.doc';
final fileResult = 'Output.doc';

//  Upload documents to cloud storage.
final firstDocumentContent = (await File(fileName1).readAsBytes()).buffer.asByteData();
final uploadFirstFileRequest = UploadFileRequest(firstDocumentContent, fileName1);
await wordsApi.uploadFile(uploadFirstFileRequest);

final secondDocumentContent = (await File(fileName2).readAsBytes()).buffer.asByteData();
final uploadSecondFileRequest = UploadFileRequest(secondDocumentContent, fileName2);
await wordsApi.uploadFile(uploadSecondFileRequest);

//  Compare documents in cloud.
final compareDataOptions = CompareData();
compareDataOptions.author = 'author';
compareDataOptions.comparingWithDocument = fileName2;
final compareDocumentRequest = 
    CompareDocumentRequest(fileName1, compareDataOptions, destFileName: fileResult);
await wordsApi.compareDocument(compareDocumentRequest);

//  Download result document from cloud storage.
final downloadFileRequest = DownloadFileRequest(fileResult);
final downloadFileResult = await wordsApi.downloadFile(downloadFileRequest);
await File('compareResult.pdf').writeAsBytes(
    downloadFileResult.buffer.asUint8List(
	downloadFileResult.offsetInBytes, downloadFileResult.lengthInBytes)
