[moazelsawaf]

Hello ❤

There are three open issues reporting a bug causing an initial zoom at the PDF document in IOS, here is the link of the issues 😢:

#117, #150, and #166

I was also facing the same bug but I wanted to give my self a try to solve it and thanks god! I did it after hours of trial 💪🏻

This answer in Stack Overflow actually helped me a lot, so big thanks goes to @Nicholas Farmer ❤

Kindly review the solution, I hope you like it.

Thanks ❤

Awesome thanks

Note: For anyone still facing the issue, make sure that you have set the value of autoSpacing to true to let the PDF auto scale it self to the size of the screen.

Anyone also still facing this problem?

                filePath: widget.path,
                enableSwipe: true,
                swipeHorizontal: true,
                autoSpacing: true,
                pageFling: true,
                
                pageSnap: true,
                defaultPage: currentPage!,
                fitPolicy: FitPolicy.BOTH,

tried also diffrent parent Elements and diffrent combination of parameters like pageFling, fitEachPage,..
The PDF Viewer is a child of a ClipRRect widget.

Thnaks for any help i get!

Make sure you have read the comments in this Pull Request, you might be missing something

Setting pageFling to false results in a slightly enlarged pdf.
But it doesn't fit properly in the container. The pageFling setting also messes up the scrolling.

Still don't see the mistake i made.

@codingwald

Please can you attach a minimal code to reproduce the issue?

This is the minimal version of the widget. Showing the PDF and everything else is working on android and ios. But on ios it still doesnt fit in. If i activate pageFling it zooms in.

pdf_viewer.dart.zip

It is still not working on ipad in landscape mode, the full pdf is opened in zoom out mode.
I did tried all alternative solution which is mentioned via enabling/ disabling flag variables
