in dart i am not able to use user details?

error:

The argument type 'String?' can't be assigned to the parameter type 'String'. (argument_type_not_assignable at [chatter_box] lib\helperServices\auth.dart:27)

code:

UserCredential result = await _firebaseAuth.signInWithCredential(credential);

User? userdetail = result.user;
SharedPreferenceHelper().saveUserEmail(result.user.email);

The error you're facing came from null-safety, the value that you're getting from the validator method can be either null or either a String, so you may want to update your code to this example:

SharedPreferenceHelper().saveUserEmail(result.user.email!);

You can learn more about null safety on official documentation:
