Switching the current PDF

[abaker2010]

So I have been trying to work with getting PDF files to change when selecting a button from the bottom navigation bar. I am able to see that the path for the pdf is getting changed and the other information for the pdf file is getting changed as well but the actual view from the plugin is not being updated. This I feel is an issue in the library that needs to be looked at. I have posted to StackOverflow about the issue and they believe that it could be an issue with the plugin. Here is the question that I posted: https://stackoverflow.com/questions/58968253/flutter-issue-with-updating-ui-on-setstate?noredirect=1#comment104210699_58968253

The code that I have posted in the question, if you replace the PdfViewer for a Text file that shows say the new index it will update the index as it is suppose to be doing.

I worked around this issue with this. Basically, when your path changes, you need to remove the PDF viewer from the screen and then put it back with the new path. I'm using a timer for this, which obviously isn't ideal. Let me know if someone has a better work around!

Widget displayPdf() {
    if (refreshPdfPath == false) {
      return PdfViewer(filePath: knownGoodPdfPath);
    } else {
      refreshPdfTimer = new Timer.periodic(
        Duration(seconds: 1),
        (Timer timer) {
          if (mounted) {
            setState(
              () {
                refreshPdfPath = false;
              },
            );
          }
        },
      );
      return Center(child: Text('Refreshing...'));
    }
  }
