Local notifications are a way to inform users when new data becomes available for your app, even when your app is not running in the foreground. For example, a city builder game may inform a user that construction is complete, and a calendar app might inform the user of an upcoming appointment.
Enable Local Notifications API
When you are ready to add local notifications to your application, activate the Local Notifications support, under the Plugin Editor UI.
You can do this by click on service name, and then activating support for the eatch platform you need.
