Hi. I’ve moved your post to the Expo SDK category. I think it fits better there
I think what you’re asking for is basically as follows:
You want the camera to capture a shot/frame, but instead of saving it to a file you want to get access to that (e.g. as a string).
In your case it seems that the actual data would need to be copied over the bridge. But if you give us more information about what you’re trying to accomplish, maybe there’s a way to avoid this.
Unfortunately I don’t believe Expo currently has a way to take the photo and somehow store/return it as a string/blob instead of saving it to a file.
Expo used to have some experimental AR functionality. Maybe something like that could be used for what you’re trying to do? If I were you I’d do some searching for info on “react native AR”.
