react-native-app-badge

Badge for the shortcut icon in your React Native App (Android & iOS).

iOS have native support for badges and this library uses the React Native PushNotificationIOS module.

In Android, this is a wrapper for the amazing ShortcutBadger library.

ShortcutBadger is included in many notification libraries for React Native, rn-shortcut-badge offers an API and updates that do not depend on any of these libraries, although it can present the same drawbacks (before Android 8 there is no native support for badges, in Android 8 and later the badge is defined by the notifications).

NOTE: This is Work In Progress, not fully tested.

Setup

$ yarn add react-native-app-badge
$ react-native link react-native-app-badge

If you are using Proguard, add this to your android/app/proguard-rules.pro
