// 26 — FORWARDING MESSAGES
// ============================================================================
//
// Forwards one or more messages from one chat into another, preserving the
// "Forwarded from" attribution. Handy for e.g. relaying an announcement
// from a source channel into your own.
//
// HOW TO RUN:
//   1. Edit sourceChatUsername, messageIds (get one from
//      29_filter_events_by_chat.dart or 40_raw_invoke_message_history.dart),
//      and destinationChatUsername below.
//   2. dart run example/26_forward_messages.dart
// ============================================================================
