public class ABTastyProvider: FeatureProvider

Metadata

The provider uses custom metadata structure:

public struct ABTastyMetadata: ProviderMetadata {
    public var name: String? = "FlagshipProvider"
}

Initialization

public init(
    envId: String,
    apiKey: String,
    configurator: FlagshipConfig
)

Parameter	Type	Description
envId	String	Environment ID provided by Flagship
apiKey	String	Api authentication key provided by Flagship.
configurator	FlagshipConfig	Custom flagship configuration. see SDK configuration

Core Methods

Initialize

Initializes the provider with optional context data. This method:

- Processes the initial context into Flagship format

- Extracts consent information

- Creates an AB Tasty client instance

public func initialize(
    initialContext: (any OpenFeature.EvaluationContext)?
) async throws

Context Management

Updates the provider context with new evaluation context data. This method:

- Converts OpenFeature context to Flagship format

- Updates consent status

- Updates visitor ID

- Updates ABTasty client with new context

public func onContextSet(
    oldContext: (any OpenFeature.EvaluationContext)?, 
    newContext: any OpenFeature.EvaluationContext
) async throws
