GroupChannel class

Represents group channel

In most case, any static or instance method will throw a SBError if anything goes wrong such as parameter is not provided or connection has not been maded. Use method with try/catch block or then/catchError callback

try {
   final channel = GroupChannel.getChannel('1234');
   //do something with channel
} catch (e) {
   //handle error
}

GroupChannel.getChannel('1234').then((channel) {
  //do seomthing with channel
}).catchError((e) {
  //handle error
})

Static Methods

createChannel(GroupChannelParams params, {OnUploadProgressCallback? progress}) → Future<GroupChannel>: #################### SECURITY TIPS #################### Before launching, you should review "Allow creating group channels from SDK" under ⚙️ Sendbird Dashboard -> Settings -> Security. It's turned on at first to simplify running samples and implementing your first code. Most apps will want to disable "Allow creating group channels from SDK" as that could cause unwanted operations. #################### SECURITY TIPS #################### Creates a channel with given params.
getChannel(String channelUrl) → Future<GroupChannel>: Gets an GroupChannel with given channelUrl
refresh(String channelUrl) → Future<GroupChannel>: Refreshes an GroupChannel with given channelUrl
