In this page you'll learn more about device segmentation. With tags, you can categorize devices through your app. Tags can assume as many forms as you want, and a device can have an unlimited number of tags. This will be extremely useful if your app doesn't have any means of authentication, and your audience is mainly composed by anonymous devices.
Tags are only available after a device has been successfully registered in Notificare, so the best place to access, add or remove them is after device registration. Add the following to retrieve the list of tags assigned to the current device:
final tags = await Notificare.device().fetchTags();
To assign multiple tags to a device, invoke the method below:
final tags = ["Flutter"]; await Notificare.device().addTags(tags);
Or remove a specific tag from a device:
Finally you can also remove all the tags from a device:
You have now successfully implemented device tags and can start sending push notifications based on these categories.
