• Context
  I used to integrate the react-native-pdf, but its dependencies are conflict with some other libraries in my react-native app. I found react-native-pdf-renderer, which is a good solution, but this library doesn't support show specific page when click a button to switch the pages. I expect to add a property page like blow

<PdfRendererView
        page={this.state.page}
        style={{backgroundColor: 'red'}}
        source="file:///path/to/local/file.pdf"
        distanceBetweenPages={16}
        maxZoom={5}
        onPageChange={(current, total) => {
          console.log(current, total);
        }}
      />

I see the android side use PdfRenderer which has method openPage, and iOS PDFKit also supports switch page.

So is it possible to add a property like page then we can pass a page number to it to navigate to a specific page? Thank you.

I think that is possible, but not trivial.

Adding a controlled page prop can open door to some unwanted behaviors, because there is no easy way to prevent user to scroll between different pages.

I think the most appropriate is to add some method like scrollToIndex from React Native FlatList.

Yes, it will also work with something like pdfViewRef.scrollToIndex. I asked for this because I'm using react-native-pdf to render pdf in my app, and there is a switch page feature which needs to change the page. The dependencies of react-native-pdf are really chaotic in some versions and has Android 16KB issues in lower versions. react-native-pdf-renderer is a better solution, using native sdk to render PDF can avoid 16KB issues.
