dispose method

Implementation

@override
void dispose() {
  // unregister event handler if the platform supports it; ignore errors if not.
  try {
    GemKitPlatform.instance
        .unregisterEventHandler(_logUploadListener.pointerId);
  } catch (_) {
    // platform may not expose unregister or may throw; swallow to ensure dispose continues
  }
  super.dispose();
}
