Getting started

Import the following package.

import 'package:syncfusion_flutter_pdfviewer/pdfviewer.dart';

Add PDF Viewer to the widget tree

Add the SfPdfViewer widget as a child of any widget. Here, the SfPdfViewer widget is added as a child of the Container widget.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: Container(
          child: SfPdfViewer.network(
              'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf')));
}

Customize the visibility of scroll head and scroll status

As a default, the SfPdfViewer displays the scroll head and scroll status. You can customize the visibility of these items using the canShowScrollHead and canShowScrollStatus properties.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: Container(
          child: SfPdfViewer.network(
              'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
              canShowScrollHead: false,
              canShowScrollStatus: false)));
}

Customize the visibility of page navigation dialog

As a default, the page navigation dialog will be displayed when the scroll head is tapped. You can customize the visibility of the page navigation dialog using the canShowPaginationDialog property.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: Container(
          child: SfPdfViewer.network(
              'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
              canShowPaginationDialog: false)));
}

Enable or disable the double-tap zoom

As a default, the SfPdfViewer will be zoomed in and out when double-tapped. You can enable or disable the double-tap zoom using the enableDoubleTapZooming property.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: Container(
          child: SfPdfViewer.network(
              'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
              enableDoubleTapZooming: false)));
}

Change the zoom level factor

The content of the document can be zoomed in and out either by pinch and zoom or changing the zoom level factor programmatically. You can change or control the zoom level factor using the zoomLevel property. The zoom level factor value can be set between 1.0 and 3.0.

PdfViewerController _pdfViewerController;

@override
void initState() {
  _pdfViewerController = PdfViewerController();
  super.initState();
}

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text('Syncfusion Flutter PdfViewer'),
      actions: <Widget>[
        IconButton(
          icon: Icon(

            color: Colors.white,
          ),
          onPressed: () {
            _pdfViewerController.zoomLevel = 2;
          },
        ),
      ],
    ),
    body: SfPdfViewer.network(
      'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
      controller: _pdfViewerController,
    ),

Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text('Syncfusion Flutter PdfViewer'),
      actions: <Widget>[
        IconButton(
          icon: Icon(
            Icons. bookmark,
            color: Colors.white,
          ),
          onPressed: () {
            _pdfViewerKey.currentState?.openBookmarkView();
          },
        ),
      ],
    ),
    body: SfPdfViewer.network(
