At least, with 1.0.70, I can correctly show the PDF on Android/Windows. Could you please show me your flutter doctor -v?

Thanks for providing a new package, it is search a valuable package to use for PDF, as of now any track of like this with many feathers i have sorted this issue it has been done. The reason of the like has some exp time so it's not loading file and get 416 error of network. I have just replaced the link with another it Woking. But I would like to check the give link valued for PDF fetch

I've identified the cause of the issue. It does not occur on the first time user opens the PDF file. When the user re-visit the same PDF file, the site let the PDF viewer to re-download the content and then the client mis-behaves due to an internal logic error.

1.0.71 contains the fix.
