Chat Full Info

// ignore_for_file: file_names, avoid_print

// ============================================================================
// 11 — CHAT FULL INFO
// ============================================================================
//
// listDialogs and Members.list give you a PtgcChat already, but a few
// fields — the "about" description in particular — only come back from
// Chats.getFullInfo, a separate round-trip Telegram requires for the
// heavier chat/channel metadata.
//
// HOW TO RUN:
//   1. Edit chatUsername below.
//   2. dart run example/11_chat_full_info.dart
// ============================================================================
