In my software, I take advantage of the flutter_pdfview:^1.2.7 package deal to show a pdf file that’s pulled from the community.
Beforehand, it’s saved on the consumer’s machine.
The applying works accurately in debugging mode and doesn’t warn about any errors. However once I created an ipa file and launched it on my machine, then within the widget the place I show a pdf doc or a picture from the community, I simply get a grey container.
What am I doing fallacious?
