How to Add a Flutter PDFViewer Widget to a Flutter App 

Hi Jose, We are glad that you have found it helpful.

Hi, The SfPdfViewer provides support for finding texts in the PDF document. To know more about text search, please refer to the following link in the UG documentation. UG documentation link: syncfusion.pulse.ly/kq6ucgnztq

Hi, You can save the added or modified annotations to the PDF document using the saveDocument method (pub.dev/documentation/syncfusion_flutter_pdfviewer/latest/pdfviewer/PdfViewerController/saveDocument.html) in the PdfViewerController class (pub.dev/documentation/syncfusion_flutter_pdfviewer/latest/pdfviewer/PdfViewerController-class.html). Code snippet: final PdfViewerController _pdfViewerController = PdfViewerController(); @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Syncfusion Flutter PDF Viewer'), actions: [ IconButton( icon: const Icon( Icons.save, color: Colors.white, ), onPressed: () async { final List savedBytes = await _pdfViewerController.saveDocument(); }, ), ], ), body: SfPdfViewer.asset( 'assets/flutter_succinctly.pdf', controller: _pdfViewerController, ), ); } Currently, the Syncfusion Flutter PDF viewer does not support exporting annotations.

Hi, Thank you for reaching out. At present we do not have support for adding annotation in Flutter SfPdfViewer. We do not have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. Kindly track the status of the feature through the following link, www.syncfusion.com/feedback/26333/support-for-ink-annotations

Hi titi MacCode, We're happy to look at this. For the fastest response to technical questions, we recommend opening a support ticket so we can exchange files and screenshots. www.syncfusion.com/support/directtrac/incidents/newincident We will check on this with our team and post a response but it will take a little time. Thanks for your question!

Hi, Currently, the Syncfusion Flutter PDF Viewer widget doesn’t allow editing or reviewing a PDF document, so the save support has not been provided yet. However, as a workaround solution, use the PdfDocument.saveSync method to obtain the loaded document bytes and save the document locally. Please refer to the following KB: www.syncfusion.com/kb/13811/how-to-save-a-pdf-document-loaded-in-the-flutter-pdf-viewer-sfpdfviewer-to-the-local

Hi Fauzi, We suspect that it could be due to the corrupted PDF document being loaded or Due to CORS security restrictions in a web application, some PDFs obtained from URLs might not be loaded in the SfPdfViewer web platform, kindly refer to the following steps to resolve the CORS security issue, Go to flutter\bin\cache and remove a file named: flutter_tools.stamp Go to flutter\packages\flutter_tools\lib\src\web and open the file chrome.dart. Find ‘--disable-extensions’. Add ‘--disable-web-security’. Kindly refer to the following like for more details about the CORS security issues, help.syncfusion.com/flutter/pdf-viewer/getting-started#load-document-from-the-network If you still reproduce the reported issue in your use case, please share the details, like the PDF document URL link and the platform on which you face an issue, to validate further and help you with an appropriate solution.

Hello Hanish Kumar, We don't support that feature at this time, but we welcome the idea of thumbnail support! Please feel free to submit a feature request here so we can consider it: www.syncfusion.com/feedback

Hello, We planned to include the 'Active viewport rendering' support in the 2024 Volume 1 release, which is expected to be rolled out in mid-March 2024. With this feature the PDF page image quality will be preserved on zooming.

Hello, We can look into this and get back to you but response times via our RU-vid videos are slower than our regular support. Have you opened a support ticket or tried our live chat? www.syncfusion.com/support/directtrac/incidents/newincident If you have a retail or flat license, you also have access to our support chat.

Yes, it is possible to navigate the desired page programmatically without any user interaction by jumpToPage (pub.dev/documentation/syncfusion_flutter_pdfviewer/latest/pdfviewer/PdfViewerController/jumpToPage.html) API which helps to navigate the specified page number in the PDF document. So, we request to jump to the previous page using this API when Navigator.pop() is invoked.

@@SyncfusionInc thank you 😊

Hi Puthea, You can download a PDF from google drive and save as byte array and then pass it to SfPdfViewer.memory().

Any documentation for beginner like me ?

Hi Puthea, You can refer to the following KB, www.syncfusion.com/kb/12757/how-to-load-a-pdf-document-from-firebase-storage-in-syncfusion-flutter-pdfviewer This is a type similar to your requirement, but not the exact one. It is a Firebase cloud but you need to do it for google drive.

Hello, Thank you for reaching out. Please refer to this, www.syncfusion.com/kb/12583/how-to-load-a-pdf-document-from-asset-in-flutter-pdf-viewer-sfpdfviewer.

Hi Frank, Yes, it is possible to load a PDF from a device. By using File picker package, the PDF bytes can be retrieved and passed to SfPdfViewer.memory (pub.dev/documentation/syncfusion_flutter_pdfviewer/latest/pdfviewer/SfPdfViewer/SfPdfViewer.memory.html) or SfPdfViewer.file constructor to load a PDF document.

@@SyncfusionInc Hi! I'm facing the same issue, the problem is with web. no Pdf is displayed and no error is shown. I can just see a blue colored linear progress indicator for a few seconds and then there is just nothing. all blank !!!

Hello Farhan, From our understanding, we believe that you couldn't use or load other document URLs (i.e., other than the one shown in the video) in our Flutter PDF Viewer. We suspect that this could be due to the CORS security limitation in the web application. There is already a bug reported on this in the flutter forum and please find the link for your reference below, github.com/flutter/flutter/issues/51125 We can overcome this issue by configuring the CORS settings in the requested server or by disabling the security settings in chrome.dart as mentioned below steps: 1. Go to flutter\bin\cache and remove a file named: flutter_tools.stamp 2. Go to flutter\packages\flutter_tools\lib\src\web and open the file chrome.dart. 3. Find '--disable-extensions'. 4. Add '--disable-web-security'. Please try the above-suggested solution and let us know whether the issue is resolved at your end or not. If you still face any issues, then please create a ticket from our support portal (www.syncfusion.com/support/directtrac/incidents/newincident) and share with us the document URL or your sample application to provide a better solution at the earliest. Note: We will cover this issue and its workaround solution in our user guide documentation as well.

Hello Abhideep, Thank you for reaching out, Please try this demo, flutter.syncfusion.com/#/pdf-viewer/getting-started and refer to this sample code, help.syncfusion.com/flutter/pdf-viewer/getting-started

@@SyncfusionInc Looks like your link is developed using the same plugin in flutter. The content gets loaded after 2-3 seconds. This is the exact problem I am facing. First comes the white page and then eventually comes the page. And then scrolling is even more bad experience. You have very good functionalities but very poor performance. The documentation link you shared, I have followed the same.

Can you please tell us the package version of syncfusion_flutter_pdfviewer you are using?

@@SyncfusionInc syncfusion_flutter_pdfviewer: ^20.1.50-beta

Hello Abhideep, Please create a support ticket with the issue reproducing document, www.syncfusion.com/support/directtrac/incidents/newincident.

Hi Dinesh, This CORS issue can be resolved by configuring the CORS settings in the requested server or by disabling the security settings in chrome.dart as mentioned in the below steps: Go to flutter\bin\cache and remove a file named: flutter_tools.stamp Go to flutter\packages\flutter_tools\lib\src\web and open the file chrome.dart. Find ‘-disable-extensions’. Add ‘-disable-web-security’.
