Flutter - Cursor keep blinking after change Form input - flutter

Question

I have a regular form on my APP, and when i load de screen no input is focused and no input has the cursor blinking...
Although, when run throw the inputs and fill them, or not, the cursor keeps blinking as i show on the image above:
The picture only show 3, but all of them are blinking. My point is that i need to keep only the focused input with the cursor blinking.
Heres the Form Code:
class RegisterView extends StatefulWidget {
const RegisterView({Key? key}) : super(key: key);
#override
State<RegisterView> createState() => _RegisterViewState();
}
class _RegisterViewState extends State<RegisterView> {
final _formKey = GlobalKey<FormState>();
final FocusScopeNode _node = FocusScopeNode();
String name = '';
String email = '';
String nif = '';
String password = '';
String _errorMessage = '';
TextEditingController nameCtrl = TextEditingController();
TextEditingController emailCtrl = TextEditingController();
TextEditingController nifCtrl = TextEditingController();
TextEditingController passwordCtrl = TextEditingController();
#override
void dispose() {
// TODO: implement dispose
_node.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
UserProvider userProvider =
Provider.of<UserProvider>(context, listen: false);
