iOS user vs environment camera

[VincentGillot]

This is working nice thank you! But I am encountering a problem with the facingMode. On iOS it always takes the user camera first, even setting the facingMode to environment, and then when closing the component and reopening it finally takes the environment camera. Any idea what could cause that? I tried many things to no effect.

There was a similar issue with Android (which led me to fork this). It might be similar, I'll take a look when I can. Feel free however to submit a pull request if you can fix it.

Only workaround at the moment is a toggle button. Boolean switches the user and environment strings. So the prop itself is working but for some reason it's like the first load doesn't detect the back camera. Maybe a racing issue? No idea.

What version of iOS are you testing against

I have the same problem on my Samsung S21 Ultra (Android 11). On initial startup, the reader starts in user view, regardless of the how the "facingMode" prop is set. As noted above, I tried adding a toggle to switch to "environment". On the first toggle attempt, I get the following error, "Could not start video source".

Long story short, a lousy workaround for now is to set the initial mode to "user", then onLoad, change the mode to "environment". The downside is that the reader window starts w/the front facing camera and then switches to the rear-facing a split second later. Would certainly like to see this issue addressed...
