Steps to reproduce

Enter text into the AutoComplete field.
Select one of the suggested items.
Press Enter to trigger textEditingController.clear().
Select the same item again from the suggestions.
Press Enter.

Expected results

After selecting an item and clearing the field with textEditingController.clear(), selecting the same item again should still work.

Actual results

After selecting an item, clearing the field with textEditingController.clear(), and selecting the same item again, it no longer works.

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

}

class _ErrorAutocompleteState extends State<ErrorAutocomplete> {
  final textCtrl = TextEditingController();
  final textFocus = FocusNode();
  final listItem = <String>['test', 'abc', 'dexter'];

  @override
  void dispose() {
    textCtrl.dispose();
    textFocus.dispose();
    super.dispose();
  }

  @override

      body: Row(
        spacing: 10,
        children: [
          Expanded(

              optionsBuilder: (textEditingValue) {
                return listItem.where(
                  (e) => e.toLowerCase().contains(
                    textEditingValue.text.toLowerCase(),
                  ),
                );
              },
            ),
          ),
          IconButton(
            onPressed: () {
