Now a days smartphone cameras are not only used for snapping photos or recording videos, but also for many purposes like Scanning Documents and Barcodes, Translating Text from one language to another, Augmented Reality Entertainment, etc... The list does not end here and it gets bigger day by day. So use of camera has become very vital these days.

We may also need to implement camera in our native mobile applications. By default, our smartphone manufacturers lock the orientation of the default camera, but the icons used alone will change according to orientation. But the package in react-native does not lock the orientation by default, which may cause the app unstable often. So we need to lock the orientation and we can change the icons alone according to orientation.

In order to use camera in our app we need to install any camera package. One of the most famous and widely used & stable package is react-native-camera.

Push Notifications are the main source of getting the user's attention to an important event that occurs in the app such as receiving a message or payment. They play a vital role in the apps conversion rates. Push notifications in react native can be accomplished with the help of many packages. OneSignal is one of them. I find it easy to configure than other packages. OneSignal can be used to send push notifications in Android, iOS & web. OneSignal is free to use.
