onEvent property

void Function(String channel, Map<String, Object?> payload)? onEvent

Every event, before it is ringed — the hook a transport reduces with.

The socket transport mirrors baseUrl and environment from the info channel into its handle file this way. The core stays ignorant of what any channel means, which is what keeps a new channel from being a change here.

Implementation

final void Function(String channel, Map<String, Object?> payload)? onEvent;
