Firebase Analytics in Flutter

Firebase Analytics in Flutter

Firebase Analytics provides powerful insights into user behavior and app performance. This guide will show you how to implement analytics tracking in your Flutter applications.

Why Use Firebase Analytics?

Firebase Analytics offers several benefits:

• User behavior tracking
• Conversion tracking
• Custom event tracking
• User segmentation
• Real-time reporting
• Integration with other Firebase services
• Free analytics solution

Implementation Steps

1. Setup Dependencies

   # pubspec.yaml
   dependencies:
     firebase_core: ^2.24.2
     firebase_analytics: ^10.7.4
   

2. Configure Firebase

   Android (android/app/src/main/AndroidManifest.xml):

   <manifest>
     <uses-permission android:name="android.permission.INTERNET"/>
   </manifest>
   

3. Create Analytics Service

   class AnalyticsService {
     final FirebaseAnalytics _analytics = FirebaseAnalytics.instance;
   
     // Screen Tracking
     Future<void> logScreenView({
       required String screenName,
       String? screenClass,
     }) async {
       await _analytics.logScreenView(
         screenName: screenName,
         screenClass: screenClass,
       );
     }
   
     // Event Tracking
     Future<void> logEvent({
       required String name,
       Map<String, dynamic>? parameters,
     }) async {
       await _analytics.logEvent(
         name: name,
         parameters: parameters,
       );
     }
   
     // User Properties
     Future<void> setUserProperty({
       required String name,
       required String value,
     }) async {
       await _analytics.setUserProperty(
         name: name,
         value: value,
       );
     }
   
     // User ID
     Future<void> setUserId(String userId) async {
       await _analytics.setUserId(id: userId);
     }
   
     // Custom Dimensions
     Future<void> setUserProperties(Map<String, String> properties) async {
       for (var entry in properties.entries) {
         await _analytics.setUserProperty(
           name: entry.key,
           value: entry.value,
         );
       }
     }
   }
   

4. Create Analytics Manager

   class AnalyticsManager {
     final AnalyticsService _analyticsService = AnalyticsService();
   
     // Screen Tracking
     Future<void> trackScreenView(String screenName) async {
       await _analyticsService.logScreenView(
         screenName: screenName,
         screenClass: screenName,
       );
     }
   
     // User Actions
     Future<void> trackButtonClick(String buttonName) async {
       await _analyticsService.logEvent(
         name: 'button_click',
         parameters: {
           'button_name': buttonName,
           'timestamp': DateTime.now().toIso8601String(),
         },
       );
     }
   
     Future<void> trackFormSubmission(String formName) async {
       await _analyticsService.logEvent(
         name: 'form_submission',
         parameters: {
           'form_name': formName,
           'timestamp': DateTime.now().toIso8601String(),
         },
       );
     }
   
     // Content Interaction
     Future<void> trackContentView(String contentId, String contentType) async {
       await _analyticsService.logEvent(
         name: 'content_view',
         parameters: {
           'content_id': contentId,
           'content_type': contentType,
           'timestamp': DateTime.now().toIso8601String(),
         },
       );
     }
   
     Future<void> trackContentShare(String contentId, String contentType) async {
       await _analyticsService.logEvent(
         name: 'content_share',
         parameters: {
           'content_id': contentId,
           'content_type': contentType,
           'timestamp': DateTime.now().toIso8601String(),
         },
       );
     }
   
     // User Properties
     Future<void> setUserProfile({
       required String userId,
       required String userRole,
       required String userPlan,
     }) async {
       await _analyticsService.setUserId(userId);
       await _analyticsService.setUserProperties({
         'user_role': userRole,
         'user_plan': userPlan,
       });
     }
   }
   

5. Create Analytics UI

   class AnalyticsScreen extends StatefulWidget {
     @override
   _AnalyticsScreenState createState() => _AnalyticsScreenState();
   }
   
   class _AnalyticsScreenState extends State<AnalyticsScreen> {
     final AnalyticsManager _analyticsManager = AnalyticsManager();
   
     @override
     void initState() {
       super.initState();
       _analyticsManager.trackScreenView('analytics_screen');
     }
   
     void _handleButtonClick(String buttonName) {
       _analyticsManager.trackButtonClick(buttonName);
     }
   
     void _handleFormSubmission(String formName) {
       _analyticsManager.trackFormSubmission(formName);
     }
   
     void _handleContentView(String contentId, String contentType) {
       _analyticsManager.trackContentView(contentId, contentType);
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           title: Text('Analytics Demo'),
         ),
         body: SingleChildScrollView(
           padding: EdgeInsets.all(16),
           child: Column(
             crossAxisAlignment: CrossAxisAlignment.stretch,
             children: [
               ElevatedButton(
                 onPressed: () => _handleButtonClick('demo_button'),
                 child: Text('Track Button Click'),
               ),
               SizedBox(height: 16),
               ElevatedButton(
                 onPressed: () => _handleFormSubmission('demo_form'),
                 child: Text('Track Form Submission'),
               ),
               SizedBox(height: 16),
               ElevatedButton(
                 onPressed: () => _handleContentView('123', 'article'),
                 child: Text('Track Content View'),
               ),
             ],
