Deleting Messages

// ignore_for_file: file_names, avoid_print

// ============================================================================
// 27 — DELETING MESSAGES
// ============================================================================
//
// `revokeForEveryone` controls whether the message disappears for the
// other participant(s) too (where Telegram allows it), or just from your
// own view of the chat. In channels, deletion is always for everyone —
// there's no "just for me" concept there, so the flag has no effect (see
// Messages.deleteMessages' doc comment).
//
// HOW TO RUN:
//   1. Edit chatUsername and messageIds below (send yourself a throwaway
//      message with 08_send_and_listen.dart first if you need one).
//   2. dart run example/27_delete_messages.dart
// ============================================================================
