How to Track Screen Views in Firebase Analytics

To track screen views in Firebase Analytics, use the logEvent method with the event name screen_view and provide parameters like screen_name and screen_class. This lets Firebase record which screens users visit in your app.

Syntax

Use the logEvent method from Firebase Analytics to record a screen view event. You specify the event name as screen_view and include parameters screen_name (the name of the screen) and screen_class (the class or type of the screen).

This tells Firebase Analytics exactly which screen the user is viewing.

javascript

firebase.analytics().logEvent('screen_view', {
  screen_name: 'HomeScreen',
  screen_class: 'MainActivity'
});

Example

This example shows how to track a screen view in a React Native app using Firebase Analytics. It logs the screen name and class whenever the user navigates to the Home screen.

javascript

import analytics from '@react-native-firebase/analytics';

async function trackHomeScreen() {
  await analytics().logEvent('screen_view', {
    screen_name: 'HomeScreen',
    screen_class: 'HomeScreenComponent'
  });
}

// Call this function when the Home screen is displayed
trackHomeScreen();

Output

No visible output; event is sent to Firebase Analytics dashboard.

Common Pitfalls

• Not including both screen_name and screen_class parameters can cause incomplete data.
• Calling logEvent too frequently or on every render can flood analytics with events.
• For native Android or iOS apps, forgetting to initialize Firebase Analytics properly will prevent tracking.

javascript

/* Wrong: Missing screen_class parameter */
firebase.analytics().logEvent('screen_view', {
  screen_name: 'SettingsScreen'
});

/* Right: Include both parameters */
firebase.analytics().logEvent('screen_view', {
  screen_name: 'SettingsScreen',
  screen_class: 'SettingsActivity'
});

Quick Reference

Parameter	Description
screen_name	Name of the screen shown to the user
screen_class	Class or type of the screen component
screen_view	Event name used to log screen views

Key Takeaways

Use firebase.analytics().logEvent('screen_view', {screen_name, screen_class}) to track screen views.

Always provide both screen_name and screen_class parameters for accurate tracking.

Avoid logging screen views too often to prevent event flooding.

Initialize Firebase Analytics correctly before tracking events.
