Edit text in Dart/Flutter SDK

Use REST API to edit text in Dart programmatically

When developers modify a text document with this Dart library, what is actually being edited is the Document Object Model (DOM). Thus, almost any changes can be made to the text document represented as DOM. With the provided Dart/Flutter SDK, developers can easily edit a document: modify text, update tables, add images and so on. Just load a text, make the necessary changes programmatically and export the result to the same or any supported save format.

Edit text in Dart using REST API

Our Dart/Flutter library gives developers the ability to modify a text document directly by editing its Document Object Model (DOM), which means no additional software needs to be installed.

Edit text in text file using Dart

The most popular case to edit a text file is text editing. With the given software solution, you can add, modify or delete text using Dart within the document.

Edit table in text file using Dart

Another popular text editing option is table editing. Our Dart/Flutter SDK allows you to work with tables and text in table cells.

Dart developers can add or remove table and table cells, as well as add, edit and remove text within them.

Add an image to text file using Dart

Besides editing text and tables in text, there is another common option: adding images to a document in Dart. Dart/Flutter developers can also add an image into a text file using DOM.

Edit text programmatically

Try this powerful Dart/Flutter SDK and evaluate some options in text document editing. Using the following example, load your text document and make some changes: add text, add a table and a table cell with text or insert an image into the text document:

Upload a document you want to modify
Run code
Upload an image you want insert
Select the target format from the list
import 'package:aspose_words_cloud/aspose_words_cloud.dart';

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

final requestDocument = (await File(
   'Input.txt').readAsBytes()).buffer.asByteData();
final requestParagraph = ParagraphInsert();
requestParagraph.text = 'Morbi enim nunc faucibus a.';

final insertParagraphRequest = InsertParagraphOnlineRequest(requestDocument, requestParagraph);
final insertParagraph = await wordsApi.insertParagraphOnline(insertParagraphRequest);

final convertRequest = ConvertDocumentRequest(insertParagraph.document.values.first, 'txt');
final convert = await wordsApi.convertDocument(convertRequest);
import 'package:aspose_words_cloud/aspose_words_cloud.dart';

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

final requestDocument = (await File(
   'Input.txt').readAsBytes()).buffer.asByteData();
final requestTable = TableInsert();
requestTable.columnsCount = 1;
requestTable.rowsCount = 2;

final insertTableRequest = InsertTableOnlineRequest(requestDocument, 
   requestTable, nodePath: '');
final insertTable = await wordsApi.insertTableOnline(insertTableRequest);

final convertRequest = ConvertDocumentRequest(insertTable.document.values.first, 'txt');
final convert = await wordsApi.convertDocument(convertRequest);
import 'package:aspose_words_cloud/aspose_words_cloud.dart';

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

final requestDocument = (await File(
   'Input1.txt').readAsBytes()).buffer.asByteData();
final requestDrawingObject = DrawingObjectInsert();
requestDrawingObject.height = 0;
requestDrawingObject.left = 0;
requestDrawingObject.top = 0;
requestDrawingObject.width = 0;
requestDrawingObject.relativeHorizontalPosition = 
   DrawingObjectInsert_RelativeHorizontalPositionEnum.margin;
requestDrawingObject.relativeVerticalPosition = 
   DrawingObjectInsert_RelativeVerticalPositionEnum.margin;
requestDrawingObject.wrapType = DrawingObjectInsert_WrapTypeEnum.inline;

final requestImageFile = (await File(
   'Input2.txt').readAsBytes()).buffer.asByteData();
final insertDrawingObjectRequest = InsertDrawingObjectOnlineRequest(requestDocument, 
   requestDrawingObject, requestImageFile, nodePath: 'sections/0');
final insertDrawingObject = 
   await wordsApi.insertDrawingObjectOnline(insertDrawingObjectOnline);

final convertRequest = ConvertDocumentRequest(insertDrawingObject.document.values.first, 
   'txt');
final convert = await wordsApi.convertDocument(convertRequest);
