Instance member 'setCurrentScreen' can't be accessed using static access - firebase

Question

I am trying to add Firebase Analytics to my flutter app to display different screen names on the dashboard. I used a method that I found here on stackoverflow in this link:
How do I track Flutter screens in Firebase analytics?
I added this code in a separate file:
import 'package:firebase_analytics/firebase_analytics.dart';
import 'package:flutter/widgets.dart';
// A Navigator observer that notifies RouteAwares of changes to state of their Route
final routeObserver = RouteObserver<PageRoute>();
mixin RouteAwareAnalytics<T extends StatefulWidget> on State<T>
implements RouteAware {
AnalyticsRoute get route;
#override
void didChangeDependencies() {
routeObserver.subscribe(this, ModalRoute.of(context) as PageRoute<dynamic>);
super.didChangeDependencies();
}
#override
void dispose() {
routeObserver.unsubscribe(this);
super.dispose();
}
#override
void didPop() {}
#override
void didPopNext() {
// Called when the top route has been popped off,
// and the current route shows up.
_setCurrentScreen(route);
}
#override
void didPush() {
// Called when the current route has been pushed.
_setCurrentScreen(route);
}
#override
void didPushNext() {}
Future<void> _setCurrentScreen(AnalyticsRoute analyticsRoute) {
print('Setting current screen to $analyticsRoute');
return FirebaseAnalytics.**setCurrentScreen**(
screenName: screenName(analyticsRoute),
screenClassOverride: screenClass(analyticsRoute),
);
}
}
enum AnalyticsRoute { screenName }
String screenClass(AnalyticsRoute route) {
switch (route) {
case AnalyticsRoute.screenName:
return 'screenName';
}
throw ArgumentError.notNull('route');
}
String screenName(AnalyticsRoute route) {
switch (route) {
case AnalyticsRoute.screenName:
return '/screenName';
}
throw ArgumentError.notNull('route');
}
I then added the route observer in the screen that I want to track.
The setCurrentScreen method is not working well and the app is not building. Any suggestions on what I could do to build it.

From the FlutterFire documentation on screen tracking:
await FirebaseAnalytics.instance
.setCurrentScreen(
screenName: 'Products'
);
