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.

Common use cases for tags involve creating categories that separated devices by device model, capabilities or properties, like tablet, hasCam or en-GB. You might also allow users to subscribe to a list of pre-defined tags you include in your app. Many use cases for tags, allow users to subscribed to categories like wants_news_for_music or subscribed_newsletter. You can also register tags upon events in your app, like bought_shoes or was_near_beacon_x.

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.deviceManager.fetchTags();

To assign multiple tags to a device, invoke the method below:

final tags = ["Flutter"];

await Notificare.deviceManager.addTags(tags);

Or remove a specific tag from a device:

await Notificare.deviceManager.removeTag("Flutter");

Finally you can also remove all the tags from a device:

await Notificare.deviceManager.clearTags();

You have now successfully implemented device tags and can start sending push notifications based on these categories.
