@override Future<void> dispose()

Releases the underlying platform ad.

Implementation

@override
Future<void> dispose() async {
  disposed = true;
  // Escape any in-flight synchronous event dispatch before closing —
  // controllers legitimately dispose a handle from its own dismiss event.
  await Future<void>.delayed(Duration.zero);
  await _content.close();
  await _paid.close();
}
