@OverRide
State createState() => _PdfViewerScreenState();

super.initState();
_initializePdfController();
}

pdfControllerPinch = PdfControllerPinch(

initialPage: widget.targetPage,
);
}

@OverRide

_initializePdfController();
} else if (oldWidget.targetPage != widget.targetPage) {
pdfControllerPinch.animateToPage(
pageNumber: widget.targetPage,
duration: Duration(milliseconds: 500),
curve: Curves.easeInOut,
);
}
}

@OverRide
