$window.ga is undefined in AngularJS event?

If $window.ga is undefined in an AngularJS event, it typically means that the Google Analytics (GA) script hasn't been loaded or initialized properly. The ga function is the global Google Analytics object used to send tracking data to Google Analytics.

Here are some possible reasons why $window.ga might be undefined and how to address them:

Google Analytics Script Not Loaded: Ensure that you have included the Google Analytics script in your HTML file before your AngularJS app is loaded. The GA script is usually added to the <head> section of your HTML file using a <script> tag.
Example:
```
html
<script async src="https://www.googletagmanager.com/gtag/js?id=YOUR_GA_TRACKING_ID"></script>
```
AngularJS Initialization Order: Make sure that the Google Analytics script is loaded before your AngularJS app is bootstrapped. If the AngularJS app initializes before the GA script is loaded, $window.ga will be undefined.
To ensure that the GA script is loaded before your AngularJS app, you can use the defer attribute in the <script> tag or place the GA script above your AngularJS app's script tag.
Example:
```
html
<script async defer src="https://www.googletagmanager.com/gtag/js?id=YOUR_GA_TRACKING_ID"></script>
<script src="path/to/your/angular-app.js"></script>
```
Check GA Initialization Code: If you are using a custom Google Analytics setup or have manually initialized GA in your AngularJS code, double-check that the initialization code has been executed successfully. For example, if you're using gtag to initialize GA, ensure that the gtag('config', 'YOUR_GA_TRACKING_ID') call is made.
Multiple Google Analytics Libraries: Avoid including multiple versions or different Google Analytics libraries in your project, as it can lead to conflicts and undefined variables.
Browser Extensions or Ad Blockers: Some browser extensions or ad blockers can interfere with Google Analytics and prevent the ga object from being available. Temporarily disable any extensions that might affect GA.

By addressing these potential issues, you should be able to ensure that $window.ga is defined and ready to be used for sending tracking data to Google Analytics in your AngularJS app.
