Can't open pdf on ios

[Angel1404]

I have an app where I save a pdf document with a path provider that I bring from a url, in andriod it works wonderfully, the pdf is saved and I can open it with the apps provided by the phone with the help of better file.
Unfortunately, the same does not work on iOS, the pdf is saved in the indicated path, everything is fine, but when going through the better file it does absolutely nothing. Has anyone had the same?
