Variables

Variables allow you to control specific aspects of your features dynamically. They are associated with feature flags and can be used to customize feature behavior.

Accessing Variables

After fetching a feature flag, you can access its variables using the GetVariable() method:

flag, err := instance.GetFlag("feature_key", userContext)
if err != nil {
    // Handle error
}

if flag.IsEnabled() {
    // Access a specific variable
    buttonColor := flag.GetVariable("button_color", "blue")
    
    // Use the variable in your code
    setButtonColor(buttonColor)
}

GetVariable() Method

GetVariable(key string, defaultValue interface{}) interface{}

Parameter	Type	Description
key Required	string	The name of the variable.
defaultValue Required	interface{}	The default value to return if the variable is not found.

GetVariables() Method

variables := flag.GetVariables()
for _, variable := range variables {
    fmt.Printf("Key: %s, Value: %v\n", variable["key"], variable["value"])
}

This method returns a slice of maps, where each map represents a variable with its key and value.
Remember that variables must be defined in your VWO dashboard for the corresponding feature flag before you can use them in your code.
