Note that onGoogleVisionBarcodesDetected returns an object containing the barcodes property, which contains an array of all the barcodes recognized in the camera. LetвЂ™s add that in the component and link it to a barcodeRecognized function to take care of it.

In order to read barcode information, we will use the onGoogleVisionBarcodesDetected prop so that we can call a function and extract the information. LetвЂ™s use RNCameraвЂ™s algorithm to recognize what is written inside each of them. Now we can see barcodes (as we can see our test QR codes showing on the monitor above) but we canвЂ™t read them yet. You must also add the following permissions to android/app/src/main/AndroidManifest.xml: package='com.cameraexample'>ДЄfter adding this code, your interface should have the camera on, full-screen, just like the screenshot below:

(There are others like Mostly automatic install with CocoaPods and Manual install, but we will stick to the first option, as itвЂ™s the most efficient.) Simply run: npm install react-native-camera -save We will use the вЂњMostly automatic install with react-nativeвЂќ option. Now itвЂ™s time to install the react-native-camera package in our project. It should look like the screenshot below: Now letвЂ™s deploy the first version of our React Native Camera example over our phone. (To be sure, there is a more detailed and up-to-date list in the docs.)ДЇirst letвЂ™s get started by creating a new React Native project: react-native init CameraExample

Our setup needs a minimum of JDK version 1.7 (which you most likely have) and if youвЂ™re on Android youвЂ™ll require buildToolsVersion newer than 25.0.2. Creating Your First App Using RNCameraД«efore we begin our React Native QR scanner, there are some dependencies weвЂ™ll need to install. Note: React Native Camera is heavily based on the Expo camera module and going back and forth between the two is pretty easy. вЂ¦so make sure to use RNCamera so that you can keep getting the latest updates. Note that RNCamera used to come in two flavors: You can build your apps around these functions without getting into the hassle of native code.

This component helps you communicate with the native OS through some simple functions so you can use device hardware.

React Native Camera (RNCamera) is the go-to component when it comes to implementing camera functionality in a React Native app. Facebook, Airbnb, Uber, and many others already have their latest apps built with React Native. React Native is a valuable framework that borrows ReactвЂ™s paradigm and design principles to enable lightning fast, cross-platform development of snappy UIs. (Note: If you need help setting this up, you can always refer to the React Native Getting Started page-donвЂ™t forget to click on the вЂњReact Native CLI QuickstartвЂќ button, as вЂњExpo CLI QuickstartвЂќ comes preselected at the time of writing this article.) Why React Native? We will be using React NativeвЂ™s CLI Quickstart. It will be able to read QR codes in real time and render their content to the screen at the time of detection.

In this React Native Camera tutorial, we will create a QR code reader app.
