在Flutter中可以知道用户当前滚动到了PDF的哪个页面吗？

dependencies:
  flutter_pdfview: ^1.0.0

import 'package:flutter/material.dart';
import 'package:flutter_pdfview/flutter_pdfview.dart';

class PDFViewerPage extends StatefulWidget {
  @override
  _PDFViewerPageState createState() => _PDFViewerPageState();
}

class _PDFViewerPageState extends State<PDFViewerPage> {
  int currentPage = 0;
  int totalPages = 0;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('PDF Viewer'),
      ),
      body: Column(
        children: [
          Expanded(
            child: PdfView(
              filePath: 'path_to_your_pdf_file.pdf',
              onPageChanged: (page, total) {
                setState(() {
                  currentPage = page;
                  totalPages = total;
                });
              },
            ),
          ),
          Text('Page $currentPage of $totalPages'),
        ],
      ),
    );
  }
}
