### Expected results

Both the views, **VideoPlayer** and **PdfViewer** should've been independent from each other, and this was the case for a very long time, it seems like something in the latest flutter upgrade has caused this issue.

### Actual results

**Issue:**
I have a video player (better_player) and as I navigate to a non-opaque route that contains a PDF (specifically, pdf_flutter which uses AndroidView to render PDFs), I see this weird issue.

PDF Flutter: https://github.com/erluxman/pdf_flutter/blob/master/lib/pdf_flutter.dart#L286

---

This issue is specific to **Android**, and only occurs when one navigates to the PDF Screen via PageTransition opaque route. I need the route to remain opaque because I want my users to read the PDF as the video plays in background.
