final
The icon color of tile's expansion arrow icon when the sublist is collapsed.
Used to override to the ListTileThemeData.iconColor.
If this property is null then ExpansionTileThemeData.collapsedIconColor is used. If that is also null and ThemeData.useMaterial3 is true, ColorScheme.onSurface is used. Otherwise, defaults to ThemeData.unselectedWidgetColor color.
