User Context

To pass additional information about the current user (including a mandatory User ID), you must create an object and use the available functions to set different properties onto this userContext object.
The userContext object must be passed as an argument whenever you call the getFlag() or trackEvent() functions.

userContext Properties

Parameter	Type	Description
id Required	String	Unique user ID for the current user. 'id' is the only required property in userContext. This ID should be a unique identifier for the current user which you need to pass to VWO. Read more here .
customVariables Optional	Object	Any additional details of the current user that you want to push to VWO can be added here as key-value pairs and can be used for targeting & pre-segmentation.

Usage

// create user context
final vwoContext = VWOContext(
  'id': userId,
  'customVariables': {'gamingCategory': 12, 'gamingType': 'firstShooter'},
};
