PDF Viewer features

• Virtual Scrolling - Easily scroll through the pages in the document with a fluent experience. The pages are rendered only when required to increase the loading and scrolling performance.

• Magnification - The content of the document can be efficiently zoomed in and out.

• Page Layout and Scroll Options - Layout the pages efficiently in a page by page (single page) scrolling mode or continuous scrolling mode. Also, scroll through pages in both horizontal and vertical direction.

• Page navigation - Navigate to the desired pages instantly.

  

• Text selection - Select text presented in a PDF document.

  

• Text search - Search for text and navigate to all its occurrences in a PDF document instantly.

  

• Bookmark navigation - Bookmarks saved in the document are loaded and made ready for easy navigation. This feature helps in navigation within the PDF document of the topics bookmarked already.

  

• Document link annotation navigation - Navigate to the desired topic or position by tapping the document link annotation of the topics in the table of contents in a PDF document.

• Hyperlink navigation - Detects hyperlinks, and tapping on the hyperlink will open the URL in a default web browser.

• Text markup annotations - Add, remove, and modify text markup annotations in PDF files. The available text markups are highlight, underline, strikethrough and squiggly. This feature will help mark important passages, emphasize specific words or phrases, indicate that certain content should be removed or indicate that text contains possible errors.

  

  

  

  

• Form filling - Fill, edit, flatten, save, export, and import AcroForm field data in a PDF document.

  

• Right to Left (RTL) - Change the user interface and functionalities such as text search and text copying to accommodate RTL languages such as Hebrew and Arabic.

• Themes - Easily switch between the light and dark theme.

  

• Localization - All static text within the PDF Viewer can be localized to any supported language.

Installation

Install the latest version from pub.

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')));
}

Web integration

We have used PdfJs for rendering the PDF page as an image on the web platform, so the script file must be referred to in your web/index.html file.

On your web/index.html file, add the following script tags, somewhere in the body of the document:

<script src="//cdnjs.cloudflare.com/ajax/libs/pdf.js/2.11.338/pdf.min.js"></script>
<script type="text/javascript">
   pdfjsLib.GlobalWorkerOptions.workerSrc = "//cdnjs.cloudflare.com/ajax/libs/pdf.js/2.11.338/pdf.worker.min.js";
</script>

Load PDF document from the Asset

The SfPdfViewer.asset creates a widget that displays the PDF document obtained from an AssetBundle.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfPdfViewer.asset(
              'assets/flutter-succinctly.pdf'));
}

Load PDF document from the Network

The SfPdfViewer.network creates a widget that displays the PDF document obtained from a URL.

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

Load PDF document from the File

The SfPdfViewer.file creates a widget that displays the PDF document obtained from a File.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfPdfViewer.file(
              File('storage/emulated/0/Download/flutter-succinctly.pdf')));
}

Load PDF document from the Memory

The SfPdfViewer.memory creates a widget that displays the PDF document obtained from the Uint8List.

@override
Widget build(BuildContext context) {
  return Scaffold(
      body: SfPdfViewer.memory(
              bytes));
}

Load encrypted PDF document

Encrypted or password-protected document can be loaded in the SfPdfViewer widget by specifying the password in password property.

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