Minimal code example

Code sample

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

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  final _formKey = GlobalKey<FormBuilderState>();
  bool showFormField = false;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Padding(
        padding: const EdgeInsets.all(20.0),
        child: SingleChildScrollView(
          child: FormBuilder(
            key: _formKey,
            child: Column(
              children: [
                if (showFormField) ...[TestFormFieldWidget(name: 'test')],

                const SizedBox(height: 1000),

                for (int i = 0; i < 3; i++) 
                  Padding(
                    padding: const EdgeInsets.all(50.0), 
                    child: TestFormFieldWidget(name: '$i'),
                  ),
              ],
            ),
          ),
        ),
      ),
      bottomSheet: Padding(
        padding: const EdgeInsets.all(20.0),
        child: Wrap(
          runSpacing: 12,
          spacing: 12,
          children: [
            ElevatedButton(
              onPressed: () {
                setState(() {
                  showFormField = true;
                });
              },
              child: Text('Show Field'),
            ),
            ElevatedButton(
              onPressed: () {
                _formKey.currentState?.saveAndValidate(autoScrollWhenFocusOnInvalid: true, focusOnInvalid: false);
              },
              child: Text('Save'),
            ),
          ],
        ),
      ),
    );
  }
}

class TestFormFieldWidget extends StatelessWidget {
  const TestFormFieldWidget({super.key, required this.name});

  final String name;

  @override
  Widget build(BuildContext context) {
    return FormBuilderTextField(name: name, textInputAction: TextInputAction.next, validator: (s) => 'Error');
  }
}

Current Behavior

autoScrollWhenFocusOnInvalid isn't scrolling to the first form field with errors inserted dynamically.

Expected Behavior

autoScrollWhenFocusOnInvalid should scroll to the first form field with errors inserted dynamically.

Steps To Reproduce

1. Run the example.
2. Click "Show Field" button, so a new form field will appear on the top.
3. Click "Save" button.
