Open and read documents in Dart

If you want to open a text file and work with the data in plain-text format, you can do it using the most basic features of the Dart language and operating system. As for reading office documents, presented in a wide variety of file formats (DOCX, DOC, PDF, RTF, ODT, HTML, etc.), this task is more difficult to solve, since such documents are described by complex tree-like data structures within the DOM model.

Our Dart library is a cloud-based solution that will allow you to open documents in any office and web format. This distributed approach gives you flexibility in software development using Dart language, as all resource-intensive document processing will take place on Aspose servers. All you need is to get private keys to access Cloud API in Dart code.

Programmatically read Word, PDF documents in Dart

You can iterate over document elements, or you can search for specific elements in the DOM tree. We provide a wide range of Dart functions both for working with the structure of the document and with the data contained in the document nodes.

The following Dart code example will help you quickly figure out how to load a document and perform some actions on it.

Upload a document you want to access
Run code
import 'package:aspose_words_cloud/aspose_words_cloud.dart';

final config = Configuration("####-####-####-####-####", "##################");
final wordsApi = WordsApi(config);
final fileName = 'Input.docx';

final requestFileContent = (await File(
   await context.loadTextFile(fileName)).readAsBytes()).buffer.asByteData();
final uploadDocumentRequest = UploadFileRequest(requestFileContent, fileName);
await wordsApi.uploadFile(uploadDocumentRequest);

final requestParagraph = ParagraphInsert();
requestParagraph.text = 'Reading and writing to the file in the cloud occurs automatically.';
final insertParagraphRequest = InsertParagraphRequest(fileName, requestParagraph);
await wordsApi.insertParagraph(insertParagraphRequest);

final downloadDocumentRequest = DownloadFileRequest(fileName);
await wordsApi.downloadFile(downloadDocumentRequest);
