ReactiveRawAutocomplete not setting correct displayValue when valueChanges

[ThomasDevApps]

Hello, I have already read and checked #123

That's why I confirm that I'm using version 2.0.1

However I have a very similar problem:

I have a company field that is autocomplete thanks to an API, however the user can also fill in the name field and the siret field manually and therefore update the autocomplete field.

However, the displayStringForOption doesn't work here: instead of using the displayNameAndSiret method to display 'companyName (companySiret)', it displays Instance of '...'.

class CompanyModel {
  final String name;
  final String siret;
  const CompanyModel({required this.name, required this.siret});

  String displayNameAndSiret() => '$name ($siret)';
}

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final formGroup = fb.group({
    'company': [const CompanyModel(name: '', siret: ''), Validators.required],
    'name': ['', Validators.required],
    'siret': ['', Validators.required],
  });

  final List<CompanyModel> list = [
    const CompanyModel(name: 'name1', siret: '01'),
    const CompanyModel(name: 'name2', siret: '02'),
    const CompanyModel(name: 'name3', siret: '03'),
  ];

  @override
  void initState() {
    formGroup.control('company').valueChanges.listen((event) {
      formGroup.control('name').value = (event as CompanyModel).name;
      formGroup.control('siret').value = event.siret;
    });
    formGroup.control('name').valueChanges.listen((event) {
      formGroup.control('company').value = CompanyModel(
        name: event,
        siret: formGroup.control('siret').value,
      );
    });
    formGroup.control('siret').valueChanges.listen((event) {
      formGroup.control('company').value = CompanyModel(
        name: formGroup.control('name').value,
        siret: event,
      );
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ReactiveForm(
        formGroup: formGroup,
        child: SafeArea(
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: [
              ReactiveRawAutocomplete(
                formControlName: 'company',
                optionsBuilder: (textEditing) => list.where(
                  (element) => element.name == textEditing.text,
                ),
                displayStringForOption: (option) =>
                    option.displayNameAndSiret(),
                optionsViewBuilder: (context, onSelected, options) {
                  return Material(
                    elevation: 4,
                    child: ListView.builder(
                      shrinkWrap: true,
                      itemCount: options.length,
                      itemBuilder: (context, index) {
                        final option = options.elementAt(index);
                        return ListTile(
                          title: Text(option.displayNameAndSiret()),
                          onTap: () => onSelected(option),
                        );
                      },
                    ),
                  );
                },
              ),
              const SizedBox(height: 16),
              ReactiveTextField(
                formControlName: 'name',
                decoration: const InputDecoration(
                  hintText: 'Name',
                ),
              ),
              const SizedBox(height: 8),
              ReactiveTextField(
                formControlName: 'siret',
                decoration: const InputDecoration(
                  hintText: 'Siret',
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}
