onDocumentLoaded in SfPdfViewer returns too early

Question

Hi! I observed that onDocumentLoaded fires in advance. Whenever my setState executes, there's still a loading progress bar shown for a few milliseconds before the actual PDF file. Here is a snippet of my code:

                            child: SfPdfViewer.network(
                              'https://cdn.syncfusion.com/content/PDFViewer/flutter-succinctly.pdf',
                              onDocumentLoaded: (_) {
                                setState(() {
                                  isLoading = false;
                                });
                              },
                            ),

If there's a way around this, replies are appreciated. Thanks!
