imageStream property

Stream<String?> imageStream

Channel image as a stream.

The channel needs to be initialized.

If an optional image argument is provided in the constructor then it will be set on extraData with a key of 'image'.

final channel = Channel(client, type, id, image: 'https://getstream.io/image.png');
print(channel.image == channel.extraData['image']); // true

Before the channel is initialized the image can be set directly:

channel.image = 'https://getstream.io/new-image';

To update the image after the channel has been initialized, call:

channel.updateImage('https://getstream.io/new-image');

This will do a partial update to update the image.

Implementation

Stream<String?> get imageStream {
  _checkInitialized();
  return extraDataStream.map((it) => it['image'] as String?);
}
