navigationBarTextSchemeColor property
Select which color from the passed in ColorScheme to use as base for the navigation bar's text color.
All colors in the color scheme are not good choices, but some work well.
If null, the default value depends on the navigationBarIsStyled value. If it is true, resulting color is primary, if false, onSurface via NavigationBar widget's default behavior. If the property is defined, the resulting ColorScheme color is always the color selected by this property.
Implementation
final SchemeColor? navigationBarTextSchemeColor;
