applePayStateUpdates property

@override Stream<String> get applePayStateUpdates

Stream of Apple Pay availability state changes from the iOS Kit's applePayAvailability.statePublisher. Each event is the raw string ("ready" / "setupRequired" / "unavailable"); the facade converts to ApplePayAvailabilityState.

Implementation

@override
Stream<String> get applePayStateUpdates {
  _applePayStateUpdatesStream ??=
      applePayStateEventChannel.receiveBroadcastStream().map((e) => e as String);
  return _applePayStateUpdatesStream!;
}
