How to show validation on submit?

submit() {
    final validEmail = _emailController.value;
    final validPassword = _passwordController.value;

    print('Email is $validEmail, and password is $validPassword');
  }

I am using a Stream/Observable to validate 'Password' text field like final _emailController = BehaviorSubject(); Stream get email => _emailController.stream.transform(validateEmail); where valdiateEmail is a StreamTransformer<String,String> to validate whether the password length is at least 6. I am trying to use the similar idea for 'Confirm Password' but the validate function would take two inputs: password, confirmPassword; not sure how to handle this using StreamTransformer.
