Rename a Chat

// ============================================================================
// 15 — RENAME A CHAT
// ============================================================================
//
// Chats.setTitle works the same way across basic groups and
// supergroups/channels — ptgc picks the right raw call for you (see the
// README's note on basic-group vs. supergroup/channel nuances).
//
// HOW TO RUN:
//   1. Edit chatUsername and newTitle below. You need "change info" rights
//      (see AdminRights.changeInfo) unless you're the creator.
//   2. dart run example/15_rename_chat.dart
// ============================================================================

const chatUsername = 'your_group_or_channel_here';
