In react native I want to add a barcode scanner and take a picture on my app but I am running in to the following error:

invariant violation: requirenativecomponent: "rncamera" was not found in the uimanager.

When barcode component view opens.

react-native-camera 3.3.0
react-native sdk-32 (expo)

Had the same problem with react-native-camera, rebuild(react-native run-android) fixed the problem. I have noticed that similar issues with other libs as well. I think linking sometimes doesn't properly take affect with just reloading

you will most likely have to eject to native code out of expo because any third party package that asks you to run the command "react-native link" as part of the setup process is strictly to be used with pure react native app. hope that helps
