Can you share the CarListPerStreetWidgetV2 widget? If this widget is a StatefulWidget, you must update that widget in the didUpdateWidget.

For example:

@override
void didUpdateWidget(covariant CarListPerStreetWidgetV2 oldWidget) {
  super.didUpdateWidget(oldWidget);
  if(oldWidget.streetName != widget.streetName) {
    setState(() {});
  }
}
