publishFlutterActionContext method
Publishes the current user-action span context to native along with an
expiry (window from now), so native span creators can parent to it while
the action window is open.

Future<void> publishFlutterActionContext(
dynamic spanContext,
Duration window,
) async {
throw UnimplementedError(
'publishFlutterActionContext() has not been implemented.',
);
}
