SchemeColor enum

Enum used to described which color from the active theme's ColorScheme should be used by certain widget sub-themes.

This enum can be used for quick color scheme based customization of sub-themes for:

• TextField in FlexSubThemes.inputDecorationTheme.
• TabBar indicator color.
• BottomNavigationBar in FlexSubThemes.bottomNavigationBar.
• NavigationBar in FlexSubThemes.navigationBarTheme.
• ChipThemeData from FlexSubThemes.chipTheme.

It can be used when opting in on opinionated sub-themes. The opinionated sub-theme for these widgets have one or more properties called nnnSchemeColor where nnn describes the color feature that can be set to a none standard ColorScheme based color. If not set the property is null and the default ColorScheme based color behavior of the opinionated sub-theme will be used. This may differ from the corresponding Widget's SDK default un-themed color behavior.

The enum selection primaryVariant and secondaryVariant colors might be best to avoid since they will deprecated in Flutter SDK soon and replaced with new Material 3 based color properties. All the new color properties in the new M3 based ColorScheme will be added when they reach the Flutter stable channel.

This enum to select and override default Widget colors when using opinionated sub-themes might be applied to more widgets in later release if so requested and desired. It should be noted though all will not be since you can still customize FlexColorScheme themes and its sub-themes totally ThemeData.copyWith methods.
