+# Google Analytics
+
+
+### Steps for Analytics Integration :-
+
+#### 1) Setup your Flutter app in Firebase console.
+
+
+#### 2) Import Plugins in pubspec.yaml
+
+   a) [firebase_analytics](https://pub.dev/packages/firebase_analytics)
+
+   b) [firebase_core](https://pub.dev/packages/firebase_core)
+
+
+#### 3) Initialize FirebaseApp in main function
+         
+         void main() async {
+         await Firebase.initializeApp();
+         runApp(FlutterAnalyticsApp());
+         }
+               
+#### 4) Initialize FirebaseAnalytics and FirebaseAnalyticsObserver
+        
+        FirebaseAnalytics analytics = FirebaseAnalytics();
+        FirebaseAnalyticsObserver observer = FirebaseAnalyticsObserver(analytics: analytics);
+
+#### 5) Setup observer to record navigation changes in app
+      
+       MaterialApp(
+   	   -------------
+         navigatorObservers: <NavigatorObserver>[observer],
+         -------------
+       );
+
+#### 6) Log Events (e.g.)
+         
+         await analytics.logEvent(
+         name: 'item',
+             parameters: <String, dynamic>{
+               'price': price,
+               'itemName': itemName,
+               'quantity': quantity,
+               'bool': addedToCart,
+             },
+         );
+
+#### 7) [Important] Enable debug mode to see events immediately
+         
+        As Events in Google/Firebase analytics takes around 24 hrs to reflect, so in order to test while developing make sure that you 
+        run a debug build. Below is the link how you can do so.
+        
+   [Enable debug mode](https://support.google.com/firebase/answer/7201382?hl=en&utm_id=ad)
