attach method
Attach to this channel ensuring the channel is created in the Ably system and all messages published on the channel are received by any channel listeners registered using RealtimeChannel.subscribe.
Any resulting channel state change will be emitted to any listeners
registered using the RealtimeChannel.on stream. As a convenience,
attach()
is called implicitly if RealtimeChannel.subscribe for the
channel is called, or RealtimePresence.enter or
RealtimePresence.subscribe are called on the RealtimePresence object
for this channel.
Implementation
Future<void> attach() => invoke(PlatformMethod.attachRealtimeChannel, {
TxTransportKeys.channelName: _channelName,
});
