How can i access a textEditingController created in another file in flutter - flutter

Question

I have two files. File 1 has a nameController and file2 has emailController and passwordController.
I want to access the nameController from file1 in file2 which has the .registerUsingEmailPassword() method .
file1
class UserName extends StatefulWidget {
const UserName({Key? key}) : super(key: key);
#override
State<UserName> createState() => _UserNameState();
}
final _registerFormKey = GlobalKey<FormState>();
final _nameTextController = TextEditingController();
...
Form(
key: _registerFormKey,
child: TextFormField(
controller: _nameTextController,
..
));
}
file2
class SignUp extends StatefulWidget {
const SignUp({Key? key}) : super(key: key);
#override
State<SignUp> createState() => _SignUpState();
}
class _MyEmailState extends State<SignUp> {
final _regFormKey = GlobalKey<FormState>();
final _emailController = TextEditingController();
final _passwordController = TextEditingController();
...
if (_regFormKey.currentState!.validate()) {
User? user = await FireAuth.registerUsingEmailPassword(
name: _nameTextController.text, // I want to access this controller from
file1
email: _emailTextController.text,
password:_passwordTextController.text,
);
}
}
Can somebody help please.

Answer 1

You must be going from file 1 to file 2 through navigator, pass the data from nameController as an argument to the Navigator like,
Navigator.of(context).pushNamed('file2Route', arguments:nameController.text);
Get the text in file2 as
var nameText = ModalRoute.of(context)!.settings.arguments as String;
Then simply use the nameText in registerUsingEmailPassword() method.
If this is not the case, please do specify.
Cheers!!

Answer 2

class SignUp extends StatefulWidget {
final TextEditingController nameController; // pass via constructor
const SignUp({Key? key,required TextEditingController nameController}) : super(key: key);
#override
State<SignUp> createState() => _SignUpState();
}
then use in build like this
if (_regFormKey.currentState!.validate()) {
User? user = await FireAuth.registerUsingEmailPassword(
name: widget.nameController.text, // use like this
email: _emailTextController.text,
password:_passwordTextController.text,
);
