  // FlexColorScheme themedSystemNavigationBar Widget tests

  // Covered quite well in flex_color_scheme_test unit test group FCS5, but
  // could potentially do more here. Current test just tests that it can build
  // an app and find an AnnotatedRegion using the themedSystemNavigationBar
  // styled SystemUiOverlayStyle. Which is certainly a bit already, as it
  // tests that it builds and works as a widget.
