How can I parse the contents of a PDF file in dart?

Question

Is there a way I can parse the contents of PDF files into widgets or something more understandable or perhaps into something that can be modified and again converted to PDF format?

Answer 1

You can use pdf library to achieve this task

import 'dart:io'; 
import 'package:pdf/pdf.dart' as pw;

Import like this and then use following method to extract text from pdf

String loadPdf({required String pdfPath}) {
  String text = "";
  // Load the PDF file
  var file = File(pdfPath);
  var bytes = file.readAsBytesSync();

  // Decode the PDF file
  var pdf = pw.PdfDocument.fromBytes(bytes);

  // Extract the text from the PDF

  for (var page in pdf.pages) {
    var pageText = page.getText();
    text += pageText;
  }
  return text;
}
