QuerySnapshot returning null in Flutter web app but gives result in the Android console

[RogerantTshibangu]

HI Guys,

I am having an issue where the QuerySnashot from the firestore giving correct value when printing in the android console but returns a null when building it on the flutter web app. Can someone please assist on what I am doing wrong?

Here is the function (returning the correct result):
countDrivers() async {
String collection = "drivers";
QuerySnapshot _myDoc = await firebaseFiretore.collection(collection).get();
List _myDocCount = _myDoc.docs;
print("Number of Drivers: ");
print(_myDocCount.length); // Count of Document
totaldriver = _myDocCount.length.toString() ;// counts the collection
print(totaldriver);

return totaldriver ;

}

and here is how I am calling it on the web app (getting a null return)
InfoCard(
title: "Number of Drivers",
value: totaldriver.toString(),
topColor: Colors.lightGreen,
onTap: () {},
),
