the problem will be gone by disabling "flutter_cached_pdfview: ^0.3.3" in pubspec.yamel
thank you.

Using this package adds up approximately 15 mb to my apk . Is there some optimization

Hello sir, not sure how to use the option "Password" to open protected pdf file, I have entered correct password but it's still show incorrect, could you please suggest for this

Thank you for your support.

In the DownloadIndicator class, if Text ('Downloading ...') appears, you should have the programmer's option to write whatever he wants in place of "Downloading".

So Text ('Downloading ...'), it should just be a Widget, which for anyone who wants to use the library should, put whatever he wants, while downloading the pdf ...

It may be the case that in place of Text ('Downloading ...'), I want to put a Gif ... or something else ...

Do you understand what I want?

Is your feature request related to a problem? Please describe.
I have a requirement whereby the users need to be provided with a draggable scrollbar. So dragging the scrollbar movement should synchronize page number in view. I tried using a draggable scrollbar plugin https://pub.dev/packages/draggable_scrollbar .

The above works in a way that DraggableScrollbar should be the parent widget of the underlying list (or pdf page in our case). The scrollable scrollbar provides a controller which needs to be passed to underlying list widget for maintaining synchronization of list position with the scroll bar position.

Since Cached_PdfView doesn't provide such controller property to which a scrollbar controller can be assigned.

Please provide a solution to the requirement which is an urgent business need. Alternatively, if there is already a solution, please direct me to the available resource to refer.

Describe the solution you'd like
The solution to the Draggable Scrollbar requirement which is integrated & synchronized with pdf view is needed.

Describe alternatives you've considered
No clear alternative found. Although I did try unsuccessfully to force-fit and integrate the 2 components that didn't work.

Additional context
NA

I dont know if this package have scroll handle . if yes kindly help me to set it in pdf view.
If this package don't have scroll handle, kindly add.

I'm using cacheFromURL, and I want to get the cached filePath in order to use it with "Share".

I'm missing something, can't find the filePath property.

Please help.

Please, update dependencies, because right now I can't integrate the library:
Because ess_front depends on flutter_cached_pdfview ^0.3.5 which depends on path_provider ^1.6.27, path_provider ^1.6.27 is required.
So, because ess_front depends on path_provider ^2.0.1, version solving failed.
pub get failed (1; So, because ess_front depends on path_provider ^2.0.1, version solving failed.)

I can't lower path_provider, because file_picker uses a newer version.

The pdf from URL is already cached by the package, so it would be super convenient to be able to share and print that cached pdf.

It would be great if I could write mine own method to implement insted of open link from pdf immediately. Then ask user if he is sure to open that link.

Describe the solution you'd like
Provide own method to handle user click on links in pdf.

Is it super easy or will need extra effort? Let me know.

This is an awesome plugin for pdf viewer in a flutter, It looks clean and easy to implement, I have tried many plugins on "pub.dev", May I ask some question how can we show page total and page controller Could you please advise.

This is awesome plugin, It's working fine when running on the emulator but I have some issue when released app to pay store, it show the error app has stopped when pdf view try to loading,
thought might need to add this line "-keep class com.shockwave.**" but not sure where need to add it,
could you please advise, thank you.

fromPath is not working
Please provide a example to load PDF fromPath as its not working for me

My Code is as below:
import 'package:flutter/material.dart';
import 'package:flutter_cached_pdfview/flutter_cached_pdfview.dart';

class PDFScreen extends StatelessWidget {
// static const String routeName = '/pdf_screen';
// final String path;
// PDFScreen({@required this.path});
@OverRide
Widget build(BuildContext context) {
final arguments = ModalRoute.of(context).settings.arguments;
print(arguments);
return Scaffold(
appBar: AppBar(
title: Text('PDF1'),
),
body: PDF().fromPath(
'/storage/emulated/0/Android/data/com.example.book_test/files/books/Book1.pdf'),
);
}
}

The above code should display the PDF but its is not
Please help me with the issue

How about adding durability to save data in the cache?.

Like this package, you can add the time that files are stored in your cache.

There is some solution for controlling the zoom, for more and for less.

I use iPhone 11 for test my project.

I used onLinkHandle for handle value text link when click a link inside PDF File.
But always safari will open after click the link inside pdf file ( etc link is "https://pub.dev". )

Can I stop open safari browser after click link inside PDF File, and just get text link with onLinkHandle without open safari browser?

On android System version 9,show this error.

How can I add pinch to Zoom?

It seems that it's enabled by default, but I can't get it to work.

Is there any special property I'm supposed to set to PDF()?

Describe the bug
Unable to zoom-in the first page of PDF in iOS devices. Once we move to the second page and come back it can be zoomed.

To Reproduce
Steps to reproduce the behavior:

• Install the application on iOS device
• Try to zoom in and out
• You will see that You can not zoom in or zoom out the first page of pdf.
• Then scroll down and try to "zoom in and out" the second page of pdf.
• Again try to "zoom in and out" of the first page.
• Now you will be able to zoom in and zoom out all the pdf pages.

Expected behavior
The pdf should be zoomable on the first page and on the initial load itself.

Smartphone (please complete the following information):

• Device: [iPhone XS]
• OS: [iOS 11]
• Browser [stock browser, safari]

Describe the bug
I can only change the Nightmode Setting only if I rebuild the complete App, if I do a hot Restart or Reload it does not change. I can also not set it to a variable and change that. (not by hardcoding it and also not with setState({})

To Reproduce
My Widget:

class PDFViewerPage extends StatefulWidget {

  PDFViewerPage(this.url);
  final url;

  @override
  _PDFViewerPageState createState() => _PDFViewerPageState(url);
}

class _PDFViewerPageState extends State<PDFViewerPage> {
  _PDFViewerPageState(this.url);
  final url;
  final bool nightmode = true;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.transparent,
      body: PDF(
        nightMode: nightmode,
      ).cachedFromUrl(
        url,
        placeholder: (progress) => Center(
          child: SpinKitWave(
            color: thomaeumRot,
          ),
        ),
        errorWidget: (error) => ErrorMessageWidget(),
      ),
    );
  }
}

Desktop (please complete the following information):

• OS: Windows 10

Smartphone (please complete the following information):

• Device: Emulator (Pixel 4XL
• OS: Android
• Version: 11.0

Describe the bug
I have a Flutter application where I am placing the PDF widget as a Saffold body. The Scaffold header has a Widget which toggles between Light and Dark mode of the app. So the toggle is working perfectly for all Widgets on the page except flutter_chached_view pdf. On change of toggle switch, I toggle a boolean variable value which is assigned to night mode property i.e.
PDF(nighMode: _boolToggle)

So the application code calls set state on change in bool value which toggles night mode for all widgets but PDF doesn't toggle between the two modes. The file remains in the mode when the PDF widget was initiated and rendered for the first time. The user needs to go back to the previous page, change the theme and then open the pdf again to view the pdf as per the updated theme.
To Reproduce

1. Create a simple flutter Material widget with Scaffold and PDF widget is defined as the body of the scaffold.
2. Create a floating action button which is supposed to toggle between the dark and light themes
3. Toggle boolean variable onPress of the FAB and call setstate().
4. Although the boolean variable value mapped to nightMode property of PDF widget is chaged, the PDF nightMode doesn't toggle between Light and Dark mode. The pdf view remains in line with the theme at first installation of the widget on page load.

Expected behaviour
On change of nightMode boolean value, the PDF view should be updated to show as per the updated mode.

Screenshots

The package is very good, congratulations. I would like to know if it is possible to search for any word in the pdf, if so please could you guide me. Thanks

Hello, native_pdf_view already supports the web. Any possible timelines for your project to support web? :)

在iOS中调用setPage返回的是当前的page，但是Android和flutter中解析的都是bool值；FlutterPDFView.m返回需要修改为true

- (void)setPage:(FlutterMethodCall*)call result:(FlutterResult)result {
    NSDictionary<NSString*, NSNumber*>* arguments = [call arguments];
    NSNumber* page = arguments[@"page"];
    
    [_pdfView goToPage: [_pdfView.document pageAtIndex: page.unsignedLongValue ]];
    result(YES);
}

Have you thought about the possibility of not only saving PDFs in cache, but also being able to save them in a database, such as sqllite data, in this package ...?

I know the component is on the screen, because I put a key on your ancestor and verified that the ancestor was found

final PDFWidget = find.byType(PDF);
expect(PDFWidget, findsOneWidget);

return _WidgetTypeFinder:<zero widgets with type "PDF" (ignoring offstage widgets)

Describe the bug
When trying to get pdf from the network, the pdf gets loaded to 100% but only a white screen is shown instead of pdf itself.
I can see this error in the log.

I'm using an iPhone 11, and I want to protect the text in side the PDF so that it can't be copied and shared.

how do turn off long tap so it can't copy text inside the pdf file when view in screen.?

Could it be possible to add support of request headers when we preview a pdf from url?
Because some api requires authentification to download files...

I like this plug-in very much, which saves me a lot of time. For example, I want to share online pdf. How can I operate it?

hi sir
In android version 4.4 pdf is not able to load. and show
Please fix the issue.
