Reload not performed on save, even without any issue

Steps to Reproduce

The following code makes reloading on save not working: contactWrapper.contact.displayName?[0] ?? ''

If I replace the above code with a Container(), for example, the hot reload works.

Here are the full code:

class ContactItem extends StatelessWidget {
  final ContactWrapper contactWrapper;

  const ContactItem({
    Key? key,
    required this.contactWrapper,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return BaseView<ContactCheckModel>(
      onModelReady: (model) => model.init(contactWrapper),
      builder: (context, model, child) {
        return ListTile(
          leading: CircleAvatar(
            backgroundColor: Theme.of(context).primaryColor,
            child: Text(
              contactWrapper.contact.displayName?[0] ?? '',
              style: TextStyle(color: Colors.white),
            ),
          ),
          title: Text(
            contactWrapper.contact.displayName ?? '',
            style: Theme.of(context).textTheme.subtitle1,
          ),
          trailing: Checkbox(
            onChanged: (bool? value) {
              model.checkContact(contactWrapper, value ?? false);
            },
            value: contactWrapper.isChecked,
          ),
        );
      },
    );
  }
}

Here is a image of the Dart Analysis not showing any error:

I’ve tried to do a Flutter Clean and restart the Dart Analysis, but the error persist.

I confirm it’s an issue in the Dart plugin. Here’s an issue to track progress: https://youtrack.jetbrains.com/issue/WEB-50212

@alexander-doroshko It looks like this is due to a bug in the PSI-based Dart parser. FlutterReloadManager.hasErrorsInFile() uses it to check for errors, and it is reporting a problem with the conditional access operator.

@vitorhm If no one responds here, you might want to open as issue at youtrack.jetbrains.com since the Dart plugin is a Jetbrains product.
