I was facing the same issue before and I used this method to solve that. In the initialUrl you can check if the url is a pdf link and use google doc to open it.

initialUrl:  widget.link!.indexOf('.pdf') != -1 ? 'https://docs.google.com/gview? 
                    embedded=true&url=${widget.link}'
                    : widget.link!
