Minimal code example

Code sample

```dart final _formKey = GlobalKey(); Widget build(BuildContext context) { return(Column(children: [ Form(key: _formKey, child: Column(children: [ FormBuilderTextField( name: 'firstname', autovalidateMode: AutovalidateMode.onUserInteraction, initialValue: '', onChanged: (text) {}, validator: (value) { return 'Required'; }, ), SizedBox(height: 30, width: 30), FormBuilderTextField( name: "lastname", autovalidateMode: AutovalidateMode.onUserInteraction, initialValue: '', onChanged: (text) {}, validator: (value) { return 'Required'; }, ), SizedBox(height: 30, width: 30), FormBuilderDateTimePicker( name: "date_of_birthday", autovalidateMode: AutovalidateMode.onUserInteraction, inputType: InputType.date initialDate: DateTime(DateTime.now().year - 30, 1, 1), onChanged: (text) {}, validator: (value) { return 'Required'; }, ) ]), TextButton(onPressed: () {_formKey.currentState?.validate() },child: Text('Submit')) ])); ```

Current Behavior

I have form with many FormBuilderTextFields, and some of them are required - (they have validator that checks if its value empty or not), when i am trying to submit the form, calling validation - _formKey.currentState?.validate(), the latest invalid FormField is being focused instead of first one. In my case the latest is FormBuilderDateTimePicker, so when i pres "Submit", the date picker is being opened.

Expected Behavior

After validation, the first invalid Field in the tree should be focused.

Steps To Reproduce

Aditional information

I suppose this is not desired behaviour, but if from some unknown reason that i haven't found this is wanted. Is there at least some way to prevent date picker from opening its picker / dialog ?

I also think that this issue is related to this - https://github.com/flutter-form-builder-ecosystem/flutter_form_builder/issues/1253, where the focused were jumped to the latest input despite there were also another invalid input above No response
