Example:

Tealium.getFromDataLayer('key')
    .then((value) => print('Value From data layer: $value')));

getConsentCategories()

Tealium.getVisitorId();
Parameter Type Description
N/A Future<String> Future returns after the Tealium.visitorId was successfully retrieved

initialize()

Initialize Tealium before calling any other method.

Tealium.initialize(config);
Parameter Type Description
config config Configuration
N/A Future<String> Future returns true if the Tealium initialization is successful, or false if there is an error

Example:

let config: TealiumConfig =
{
	account: 'ACCOUNT',

setVisitorServiceListener()

Sets a callback to execute when the visitor profile is updated. The updated VisitorProfile is provided in the callback response.

The VisitorService module implements the Data Layer Enrichment feature of the Tealium Customer Data Hub.

If you are not licensed for AudienceStream, usage of this module is not recommended as no visitor profile is returned.

callback Function Code to execute after the updated visitor profile returns

Example:

Tealium.setVisitorServiceListener((profile) => {
    print(JsonEncoder().convert(profile));
