How can we retrieve the details of the Camera?

[felixchan]

For example, I'd like the field of view of the default camera.

Try using react-native-vision-camera and fetch the device like this:

const devices = await Camera.getAvailableCameraDevices()
const devicesViro = devices
  .filter(d => d.position === "back")
  .filter(d => d.supportsParallelVideoProcessing)
// use Viro's view's measured dimensions to determine fieldOfView of used device's format
