The web implementation of firebase_analytics

firebase_analytics_web #

The web implementation of firebase_analytics

Usage #

Import the package #

This package is the endorsed implementation of firebase_analytics for the web platform since version 5.0.16, so it gets automatically added to your application by depending on firebase_analytics: ^5.0.16.

No further modifications to your pubspec.yaml should be required in a recent enough version of Flutter (>=1.12.13+hotfix.4):

...
dependencies:
  ...
  firebase_analytics: ^5.0.16
  ...

Update index.html #

Due to this bug in dartdevc, you will need to manually add the Firebase JavaScript files to your index.html file.

In your app directory, edit web/index.html to add the following:

<html>
  ...
  <body>
    <script src="https://www.gstatic.com/firebasejs/7.14.3/firebase-app.js"></script>
    <script src="https://www.gstatic.com/firebasejs/7.14.3/firebase-analytics.js"></script>
    <!-- Other firebase SDKs/config here -->
    <script src="main.dart.js"></script>
  </body>
</html>

Initialize Firebase #

If your app is using the "default" Firebase app (this means that you're not doing any package:firebase_core initialization yourself), you'll need to initialize it now, following the steps in the Firebase Web Setup docs.

Specifically, you'll want to add the following lines to your web/index.html file:

<body>
  <!-- Previously loaded Firebase SDKs -->

  <!-- ADD THIS BEFORE YOUR main.dart.js SCRIPT -->
  <script>
    // TODO: Replace the following with your app's Firebase project configuration.
    // See: https://support.google.com/firebase/answer/7015592
    var firebaseConfig = {
      apiKey: "...",
      authDomain: "[YOUR_PROJECT].firebaseapp.com",
      databaseURL: "https://[YOUR_PROJECT].firebaseio.com",
      projectId: "[YOUR_PROJECT]",
      storageBucket: "[YOUR_PROJECT].appspot.com",
      messagingSenderId: "...",
      appId: "1:...:web:...",
      measurementId: "G-..."
    };
    // Initialize Firebase
    firebase.initializeApp(firebaseConfig);
    // Initialize Analytics
    firebase.analytics();
  </script>
  <!-- END OF FIREBASE INIT CODE -->

  <script src="main.dart.js"></script>
</body>

Use the plugin #

Once you have modified your web/index.html file, you should be able to use package:firebase_analytics as normal. Refer to the firebase_analytics documentation for more details.
