Logging Out

// ignore_for_file: file_names, avoid_print

// ============================================================================
// 36 — LOGGING OUT
// ============================================================================
//
// auth.logOut() revokes the session server-side — Telegram invalidates the
// auth key, so it can't be reused even if someone got hold of the saved
// session file. It also clears TelegramClient.sessionStore locally. This is
// different from disconnect(), which just closes the socket without
// revoking anything — see the doc comment on auth.logOut for that
// distinction.
//
// HOW TO RUN:
//   dart run example/36_log_out.dart
//   (you'll need to run 01_login.dart again afterwards — this really does
//   revoke the session)
// ============================================================================
