Retrieve a channel by URL

Since a channel URL is a unique identifier of a channel, you can use a URL when retrieving a channel object. We recommend that you store a user's channel URLs to handle the lifecycle or state changes of your app as well as any other unexpected situations. For example, when a user is disconnected from the Sendbird server by temporarily switching to another app, you can provide a smooth restoration of the user's state once the user has returned to your app by using the stored URL to fetch the appropriate channel instance.

try {
  final groupChannel = await GroupChannel.getChannel('CHANNEL_URL');
  final openChannel = await OpenChannel.getChannel('CHANNEL_URL');
} catch (e) {
  // Handle error.
}
