How to show validation on submit?

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

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

Try this, or add more validations for example min lenght or something else

submit() {
    if (email.length == 0) {
      _emailController.sink.addError('This field cannot be empty');
    }

    if (pass.length == 0) {
      _passController.sink.addError('This field cannot be empty');
    }
  }
