what are the errors?

one sec

#

CameraType is a type, not a value

#

it's "front" | "back"

#

you'd use those strings literally

#

it's not an enum

#

when you do useState(null), ts doesn't know if you want other types as well, it's just a state typed null
you have to specify what type it should have

#

useRef as well

#

useState("back") would have a similar problem, so for that, use useState<CameraType>("back")

north thorn
#

well yeah that does make more sense

#

And here?

#

well, what's the error

north thorn
#

let me rerun for a sec

lapis junco
#

looks like a type error, so this won't show up in your app

#

just hover over the error

north thorn
#

"Camera can not be used as a JSX Componet"

#

And that confuses me too?

docs are showing it should be CameraView

#

@lapis junco
Do you know why this Exit Func is not working?

<TouchableOpacity 
            style={[styles.button, styles.exitButton]} 
            onPress={onExit}
          >
#

no error, just nothing is happening

#
