Please modify the code under your try block as below

try {
  final authResult = await FirebaseAuth.instance.signInWithCredential(credential);

  if (authResult.additionalUserInfo!.isNewUser) {
        await FirebaseFirestore.instance
            .collection('Users')
            .doc(authResult.user!.uid)
            .set({
          "Name": authResult.user!.displayName,
          "Email": authResult.user!.email,
        });
      }

  if (mounted) return;
  InfoBox.show(context, InfoBox.success, "Signed In With Google");

 
} on Exception catch (e) {
  if (mounted) return;
  InfoBox.show(context, InfoBox.success, e.toString());
}

Please accept the solution if it solves your problem

Inside your try block, you have to get UserCredential which gives the User object data to be saved in the next line.

    try{
    UserCredential userCredential = await FirebaseAuth.instance.signInWithCredential(credential);
User user = userCredential.user; // User is updated version of FirebaseUser
FirebaseFirestore.instance.collection('users').doc(user.uid).set(/*Add Mapped User object*/);}
