File transfer from Native to Web

[techyrajeev]

Hi Team,
Is there any way I can transfer files from native to web via interop calls?

I want to transfer image files [png, jpeg] from native to web.

Hey @techyrajeev - Are you trying to display them? If so, you can probably use SetVirtualHostNameToFolderMapping and use that to reference the images that are on disk.

So there's nothing more generic for binary data transfer between native and web? For both directions?

For Web <-> Native, please see our docs for more info:

Mostly it relies on strings/object - for binary specifically, we are tracking that work in #1005. Thanks!
