as I state on the title, I want to develop a project that having ability to open PDF file within the App (React Native), then later we can add annotation, notes, and sign on the PDF (put writing). The pdf is from the server, so I assume we can call some kind of library that can open pdf and edit and have those features.
I tried browsing about it and found that PSPDFKit can be a solution, but the pricing is pretty much expensive. Is there any other library that can be use for this purpose?
