Setting a badge number is only supported on iOS. To imperatively set the badge number you can use e.g. PushNotificationIOS.setApplicationIconBadgeNumber. See how to set up PushNotificationIOS in the RN docs.
There are also a number of 3rd party libraries available to accomplish this, with push notification handling for both Android and iOS, should you need that.
Although "vanilla" Android does not support badge numbers, the same effect can be achieved by using a widget or a custom launcher. For further info, see this question.
