CodePudding user response：
Just wrap your ResetPassword() method like below:
if (_formKey.currentState!.validate()) {
Resetpassword();
}
This will check the validation.
Make sure key in attached to Form widget not Container
class ForgetPasswordForm extends StatefulWidget {
const ForgetPasswordForm({Key? key}) : super(key: key);
@override
_ForgetPasswordFormState createState() => _ForgetPasswordFormState();
}
class _ForgetPasswordFormState extends State<ForgetPasswordForm> {
final _formKey = GlobalKey<FormState>();
String email = "";
Future Resetpassword() async {
print("123");
}
@override
Widget build(BuildContext context) {
return SingleChildScrollView(
child: Form(
key: _formKey,
autovalidateMode: AutovalidateMode.disabled,

}

Can I have a screenshot of your login screen and the forgotten password screen? I don't quite understand your question.
