Ionic 4 - Right way to display local PDFs in Android/IOS

What is the right way to display local PDFs in Ionic 4? Is there an ionic component to do it or is it always going to be a native solution - which can’t be previewed except on a device?

i am using this package to display pdf

There is a stenciljs version that is very impressive. Sorry that I don’t remember the name.

I’ve never used that. Can you point me to any examples of this working with iconic 4?
