ChannelAvatar

The ChannelAvatar allows you to display a channel avatar, that shows the channel image, or a grid of its active members.

Let’s see how to integrate the component into your code.

Usage

With a bit of extra code for the rest of the content, when selecting a channel, the snippet above will produce the next UI:

ChannelAvatar(
    channel = channel,
    // The current logged in user
    currentUser = currentUser,
    // Reasonable avatar size
    modifier = Modifier.size(36.dp)
)

Based on the state of the Channel and the number of members, it shows different types of images:

Handling Actions

The ChannelAvatar component exposes a single action to handle click events:

@Composable
fun ChannelAvatar(
    ..., // State
    onClick: (() -> Unit)? = null,
)

If you want to handle clicks on ChannelAvatar, you can use the code below:

fun ChannelAvatar(
    ..., // State
) {
    // Handle avatar clicks here
}

Customization

In terms of UI customization, the ChannelAvatar exposes the following properties:

@Composable
fun ChannelAvatar(
    channel: Channel,
    currentUser: User?,
    modifier: Modifier = Modifier,
    shape: Shape = ChatTheme.shapes.avatar,
    contentDescription: String? = null,
    showOnlineIndicator: Boolean = true,
    onlineIndicatorAlignment: OnlineIndicatorAlignment = OnlineIndicatorAlignment.TopEnd,
    onlineIndicator: @Composable BoxScope.() -> Unit = {
        OnlineIndicator(modifier = Modifier.align(onlineIndicatorAlignment.alignment))
    },
)

• channel: The channel whose data we need to show.
• currentUser: The current user, used to determine avatar data.
• modifier: Modifier for the root component. Useful for things like the component size, padding, background and similar.
• shape: The shape of the avatar.
• contentDescription: The content description of the avatar.
• showOnlineIndicator: If we show online indicator or not.
• onlineIndicatorAlignment: The alignment of online indicator.
• onlineIndicator: Custom composable that allows replacing the default online indicator.

Here’s an example of customizing the UI of the channel avatar:

ChannelAvatar(
    channel = channel,
    currentUser = currentUser,
    modifier = Modifier.size(48.dp),
    shape = RoundedCornerShape(8.dp)
)

The sample above will produce a custom channel avatar with rounded corners:
