Branch: develop

Device: Note 9, Android 10

Steps to reproduce:

PDFViewer(
  document: _doc!, // Any valid .pdf document
  lazyLoad: false,
  showPicker: false,
  showNavigation: false,
  scrollDirection: Axis.vertical,
  progressIndicator: const CupertinoActivityIndicator(),
),

Same issue since the update of android embedding (dev or https://github.com/enveraltin/pdf_viewer.git)

@kNoAPP @gtu-myowin is the file you're trying to open local or remote?

[gtu-myowin]

@enveraltin The crash happens for both local (Inside Application Documents Directory) and remote files.
