 #### Add global attribute
 
 1. Add global attributes when initializing the SDK

+   The following example code shows how to add traffic source fields as global attributes when initializing the SDK.
    ```dart
    analytics.init({
      appId: "your appId",
      endpoint: "https://example.com/collect",
      globalAttributes: {
