EventContext class

Context information for a table change event

Wraps an Event with the current client's connection ID, providing convenience methods and helpers for common operations.

The context allows event handlers to:

• Access transaction metadata (timestamp, reducer name, caller, etc.)
• Check if the transaction was initiated by the current client

Example:

noteTable.insertEventStream.listen((event) {
  final ctx = event.context;

  if (ctx.isMyTransaction) {
    print('I created this note!');
  } else {
    print('Someone else created this note');
  }

  // Access event metadata
  if (ctx.event is ReducerEvent) {
    final reducerEvent = ctx.event as ReducerEvent;
    print('Reducer: ${reducerEvent.reducerName}');
  }
});
