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>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: [
          FormBuilder(
            key: formKey,
            child: Column(
              children: [
                FormBuilderTextField(name: 'text', onChanged: (v) => formKey.currentState?.fields['checkbox']?.didChange(true)),
                FormBuilderCheckbox(name: 'checkbox', title: const Text('Checkbox')),
              ],
            ),
          ),
        ],
      ),
    );
  }
}

Current Behavior

Calling didChange() focuses the checkbox(and lost focus if you were using the text field)

Expected Behavior

This is what was happening in the previous version:
Calling didChange() doesn't focus the checkbox(and keep focusing the text field if you were using it)

Is there a new way to keep this behavior? Or is this a bug?

Steps To Reproduce

Type something in the text field, so didChange will be triggered
