Hi Saber, 

We can read the PDF document from webspace/website by using the HTTP package and drawn the text. Kindly try the following code example in your end.

1.  Add http package in dependencies section of pubspec.yaml file

dependencies: 

  http: ^0.13.4 

2. Import the following package in your dart file.

import 'package:http/http.dart' show get; 

3. Get image data

4. //Read an PDF from website/webspace
5.     var url = Uri(
6.         path:
7.             Input pdf address link);
8.  
9.     var response = await get(url);
10.     var data = response.bodyBytes;

4. Drawstring in PDF

5. // Create a new PDF document
6.     PdfDocument document = PdfDocument(inputBytes: data);
7.     // PdfDocument document = PdfDocument();
8.  
9.     //Draw string on the existing page graphics
10.     document.pages[0].graphics.drawString(
11.         "Sample text content", new PdfStandardFont(PdfFontFamily.helvetica, 17),
12.         bounds: const Rect.fromLTWH(100, 20, 200, 50));
13.     //Save and launch the document
14.     final List<int> bytes = document.save();
15.     //Dispose the document.
16.     document.dispose();

Kindly refer to the following articles for more details,
