Answer 1

Pass profileNameTextEditingController as argument to createProfileNameTextFormField and then use it in controller.

Column createProfileNameTextFormField(profileNameTextEditingController) {
  return Column(
    ...
    TextField(
      controller: profileNameTextEditingController,
    ),
  );
}

Answer 2

'profileNameTextEditingController' scope is only within the class _editProfileState. Just pass controller as argument to the function where its needed.

createProfileNameTextFormField(profileNameTextEditingController);

Column createProfileNameTextFormField(profileNameTextEditingController) {
  
}
