# Flag / Unflag User

Flag / Unflag User feature is an essential tool for maintaining a safe and engaging chat community. With social.plus, you can use the flag and unflag user feature to allow moderators and administrators to monitor any inappropriate behavior within a chat channel.

In this section, we will discuss how to use the flag and unflag user feature of social.plus Chat SDK to maintain a safe and engaging chat community.

To flag / unflag users on iOS, Android and Flutter SDK, create an instance of `UserFlagger` first:

{% tabs %}
{% tab title="iOS" %}

```swift
let userRepository: AmityUserRepository = AmityUserRepository(client: client)
let userToBeFlaggedObject: AmityObject<AmityUser> = userRepository.user(forId: "badUser")

guard let userToBeFlagged: AmityUser = userToBeFlaggedObject.object else { return }

let userFlagger = AmityUserFlagger(client: client, userId: IdOfuserToBeFlagged)
```

{% endtab %}

{% tab title="Android" %}
{% embed url="<https://gist.github.com/amythee/860855679f2040d319a63670e1d329f7#file-amityuserflaginitialization-kt>" %}
{% endtab %}

{% tab title="Flutter" %}
{% embed url="<https://gist.github.com/amythee/17854e36bf88b63a20e53f4ef8379a1f#file-amityuserflaginitialization-dart>" %}
{% endtab %}
{% endtabs %}

The `UserFlagger` lets you flag and unflag a user. It also exposes an asynchronous way to check whether the current logged-in user has already flagged the given user or not.
