delete method

@override Future<ChatResult<void>> delete(String roomId, String messageId)

Deletes a message from a room.

Senders can always delete their own messages; admins/owners can delete anyone's. The backend tombstones the message (it stays in the timeline marked as deleted, so reply chains keep working) and emits MessageDeletedEvent. Hard removal is not exposed via the SDK.

Implementation

@override
Future<ChatResult<void>> delete(String roomId, String messageId) async {
  _client._messages[roomId]?.removeWhere((m) => m.id == messageId);
  return const ChatSuccess(null);
}
