RNCamera of react-native-camera is heavily based on Expo camera module. Thanks @aalices and Expo for the great work.

So you don't need to use react-native-camera if you have the following config:

• If you are using Expo
• If you are using create-react-native-app
• If you eject a create-react-native-app app and are using ExpoKit

How to migrate from Expo to react-native-camera

If you decide to eject without using ExpoKit, you can follow react-native-camera installation instructions and just change the usage of your Camera component to RNCamera:

- import { Camera } from 'expo';
+ import { RNCamera } from 'react-native-camera';

- <Camera
+ <RNCamera

How to migrate from react-native-camera to Expo Camera Module

- import { RNCamera } from 'react-native-camera';
+ import { Camera } from 'expo';

- <RNCamera
+ <Camera
