Unhandled Exception: PlatformException(Error performing get, PERMISSION_DENIED: Missing or insufficient permissions., null)

Whenever the app starts this error comes. i think the error mainly is in the saveUserInfoFirestore function.. i saw that many other people have this same problem cause of their firestore security rules but i tried differenct rules it still shows same error..

final GoogleSignIn gSignIn = GoogleSignIn();
final userReference = Firestore.instance.collection("Users");    
void initState(){
        super.initState();
        pageController=PageController();
        gSignIn.onCurrentUserChanged.listen((gSigninAccount) { ControlSingIn(gSigninAccount); },
            onError: (gError){
                print("Google signin error"+ gError);
            });
        gSignIn.signInSilently(suppressErrors: false).then((gSigninAccount) { ControlSingIn(gSigninAccount); }).
        catchError((onError){
          print("Signin silently error"+ onError);
        });
      }
    
      ControlSingIn(GoogleSignInAccount signInAccount) async{
    
        if(signInAccount != null){
          await saveUserInfotoFirestore();
          setState(() {
            isSignin = true;
          });
        }else{
          setState(() {
            isSignin = false;
          });
        }
    
      }
      saveUserInfotoFirestore() async{
          final GoogleSignInAccount gCurrentuser = gSignIn.currentUser;
          DocumentSnapshot documentSnapshot = await userReference.document(gCurrentuser.id).get();
    
          if(!documentSnapshot.exists){
            final username = await Navigator.push(context, MaterialPageRoute(builder: (context)=>CreateAccountPage()));
    
            userReference.document(gCurrentuser.id).setData({
              "id": gCurrentuser.id,
              "profileName": gCurrentuser.displayName,
              "username": username,
              "url": gCurrentuser.photoUrl,
              "email": gCurrentuser.email,
              "bio": "",
              "timestamp":timestamp
            });
            documentSnapshot = await userReference.document(gCurrentuser.id).get();
    
          }
          currentUser = User.fromDocument(documentSnapshot);
    
      }

heres the firestore security rule that i am using:

rules_version = '2';
// Allow read/write access on all documents to any user signed in to the application
service cloud.firestore {
  match /databases/{database}/documents {
    match /messages/{document=**} {
      allow read, write: if true;
    }
  }
}

Your security rules only allow access to a single collection called "messages" using this match:

    match /messages/{document=**} {
      allow read, write: if true;
    }

However, your code is trying to write a different collection called "Users". You are seeing a permission error because your rules don't allow any access at all to that collection. You will have to write another rule to allow enough access to that collection as well.

I strongly suggest fully reviewing the documentation for security rules to understand how best to protect your app.

check with your googleservices.json file if it is in the right location. It should be in your project>android folder> app folder>
