    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());
}

    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*/);}

    You can use user object to get all the necessary data.
