Application crashes when wrong document is set in assets

So I made a mistake in writing the file name from the assets and application crashes.

Plugin should probably handle this. I am not sure if the same happens when calling openFile with wrong filePath, but for sure it crashes when using openAsset.

CrashLog:

[native_pdf_view] Provide a onPageChanged callback

Is your feature request related to a problem? Please describe.
We would like to show the user that he is on page 1/n,

Describe the solution you'd like
To achieve that I believe that a simple onPageChanged callback could be easily implemented and would give us a lot of flexibility.

Describe alternatives you've considered
A built-in page indicator would also work, but might not fit into the UI of every app.

Additional context

Not possible to catch plugin errors, application just crashes

Describe the bug
There is no way to catch plugin error.

To Reproduce
Simplest way to reproduce - try to open non existing file.

Expected behavior
It should be possible to catch plugin errors. Example with non existing file is just example, in my case I observe some crashes because of some file format problems in some rare cases in production.

I already tried all 4 possible solution I know to catch dart/flutter errors, none of them works, application just crashes.

native_pdf_view: ^2.2.0

[native_pdf_view] Vertical smooth viewer

I am trying to switch from pdf_viewer_plugin to your package but I am not able to implement the same user experience as I have in the existing plugin.

What I need is vertical viewer with smooth scrolling. I need the page to load in full available width size (both in portrait and horizontal orientation). I need pinch/zoom possibility. The zoom should not reset when the new page is detected.

Basically, it should look like all pdf pages are merged vertically as the one big page and initially shown in the full available width space, with zoom and pinch possibility.

Can you please help me archive that with your plugin.

highlight text on epub_view and getting chapters

Hello dear
Thank you very much for your great work on this project.

i would like to know if you have plan to add text highlight as you know it is necessary for ebook reader.

Also it is necessary to get chapters for example to show it on a drawer for chapter navigations

Cannot build apk release (compileSdkVersion 29)

I can't build apk release (my compileSdkVersion is 29)
I get this error:

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':native_pdf_renderer:verifyReleaseResources'.

java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: Android resource linking failed

flutter\build\native_pdf_renderer\intermediates\res\merged\release\values\values.xml:236: error: resource android:attr/fontVariationSettings not found.
flutter\build\native_pdf_renderer\intermediates\res\merged\release\values\values.xml:237: error: resource android:attr/ttcIndex not found.
error: failed linking references.

To resolve this error i increase compileSdkVersion in build.gradle of module native_pdf_rendererfrom 27 to 28

I found this solution here

crosswalk-project/cordova-plugin-crosswalk-webview#207 (comment)

So you need to increase compileSdkVersion to 28 in source code.
Thanks

[native_pdf_view] get pdf page count

It would be helpful if there was a way to get the currently opened pdf's page count.

At this moment, i'm not sure how one can get this number other than brute forcing by jumping to a page and seeing if the onPageChanged callback is fired or not.

how can get the current show page?

Describe the bug
Forgive my poor english,I want to show the pdf automatic and i used Future.periodic and pageController.nextPage api, but how can i get the current show page to stop the animation or go to the first page?

Changelog is wrong

Something went wrong in the changelog regarding 2.0.0

shouldn't it be PDF on the left hand side? And not Pdf?

PdfView.builder zoom full width

I would like to have pages render at full screen width when loaded.

1. is there a standard way to achieve this?

2. I believe I can use the Custom Page Builder referenced in the documentation.
   However, PdfView.builder does not seem to be a standard type for this class.
   Is there a more complete example showing how to use PdfView.builder?

Thank you,
Great Package!

[epub_view] Chapters navigation

Hello. I have a book and it contains 300+ titles. How can I get all of these titles? I want to make a menu of contents.

controller loadDocument parameter not used

Can you please explain me how the parameter is used in the loadDocument method:

`
/// Load document
Future loadDocument(Future documentFuture) {
if (_pdfViewState != null) {
return null;
}
_pdfViewState._changeLoadingState(_PdfViewLoadingState.loading);
return _loadDocument(document);
}

3. Rename pubspec.yaml asset file reference from sample.pdf to 日本語.pdf
4. Change sample.pdf String in main.dart to 日本語.pdf
5. packages get

Add a way to render a subset of a PDF page

Package name
native_pdf_renderer

Describe the solution you'd like
To be able to specify a rectangle in the coordinates of the PDF page to specify what to render.

Describe alternatives you've considered
The alternative is to render the entire page and then copy the part you want.

Using AutoAnimatedSliverList with Dismissible child causes list to redraw when OnDismissed() gets called

Describe the bug
My Dismissible widget contains

setState((){
_items.removeAt(index);
})

callback in onDismissed() method.

Previously I used SliverList, and it handled it perfectly -- item was removed without any errors. Now, with AutoAnimatedSliverList(), my onDismissed() method causes whole list to redraw and scroll to top.

To Reproduce
Steps to reproduce the behavior:

1. Use Dismissible() widget as a child for AutoAnimatedSliverList();
2. Try to swipe on element;
3. See AutoAnimatedSliverList redrawed.

Expected behavior
I expected it to behave as SliverList, handling Dismissible behavior under the hood.

At least it must be explained in documentation on how to solve similar issue, probably using some GlobalKey.

Repeatedly loaded PDF file doesn't replace previous pages

If I read the new PDF file instead of the existing one (eg. using a StreamBuilder), already rendered and probably cached pages will not be replaced with the pages from the new file. Only pages not yet visited in the previous PDF will be rendered correctly.

Expected behavior
Loading a new PDF should invalidate previously cached pages.

Kotlin plugin should be enabled before ‘kotlin-kapt’ error in Android Studio

Supposedly this only happens in Android Studio 3.5+.
This is based on a post found here https://www.tutorialkart.com/kotlin-android/kotlin-plugin-should-be-enabled-before-kotlin-kapt/

To fix, change the following in build.gradle
BEFORE

apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-android'

AFTER

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

Add possibility to define infinite zoom parameter

Is your feature request related to a problem? Please describe.
Actually I started using this package due to the fact that it uses the native iOS and Android API.
I need to permit user to zoom infinitely on my PDFView, but now zoom is not simply settable. In some PDF page the actual zoom is not enough.

Describe the solution you'd like
It will be beautiful to add a parameter on PDFView widget in order to set the maximum PDF zoom/zoomRatio in a simply way. Something like:

return PDFView(
                  document: snapshot.data,
                  infiniteZoom: true/false,
                  // or maxZoomRatio: 4.0,
                );

Can it be possible?

Thank you

page not loaded when onDocumentLoaded and onPageChanged are not set

I don't have a need to be notified of onDocumentLoaded and onPageChanged events. Since the arguments are not marked as mandatory I didn't set onDocumentLoaded and onPageChanged.

As I saw your code expects that this callbacks are set and loading document crashes...

You should probably mark fields as mandatory or do a null check in the code before calling methods.

PdfView called by Consumer build

I have two different documents to display.
One in English - doc_en.pdf, and one in German - doc_de.pdf.
In the user settings page of the app, the user can change an instance of UserPrefs.

The mainApp is enclosed with

ChangeNotifierProvider<UserPrefs>.value(
        value: userPrefs,
        child: MaterialApp(

I have tried several schemes to enclose PdfView with a Consumer

PdfController pdfController;

Widget _buildPdfView(String documentName) {
      if (pdfController != null) {
        pdfController.dispose();
      }
      pdfController =
          PdfController(document: PdfDocument.openAsset(documentName));
      return PdfView(key: Key('PdfView'), controller: pdfController);
    }

Consumer<UserPrefs>(builder: (context, prefs, child) {
              String displayPdf =
                  'assets/pdf/${widget.docTitle}/${widget.docTitle}_${prefs.getLang()}.pdf';
              print(displayPdf);   // prints correct result
              return _buildPdfView(displayPdf);

The document displays properly when the app is started.
However, when the UserPrefs object is changed, the app raises an exception with

════════ Exception caught by widgets library ═══════════════════════════════════
The following NoSuchMethodError was thrown building PdfView-[<'PdfView'>](dirty, dependencies: [_EffectiveTickerMode], state: _PdfViewState#13f6e(ticker inactive and muted)):
The getter 'pagesCount' was called on null.
Receiver: null
Tried calling: pagesCount

Is there a way to use PdfView inside a Consumer block?

No correct scrolling for one page possible

2. Open the PDF View
3. Smartphone in landscape
4. Scrolle up and down to see the bug

page take a noticeable time to load

when the pdf file is loaded pages takes time to load even in release which is pretty annoying for book readers and it is even worse for pages that contain images, is there any to make it faster?
