Create a high contrast ColorScheme based on the dark baseline Material 2 color scheme.

This constructor shouldn't be used to update the Material 3 color scheme.

For Material 3, use ColorScheme.fromSeed to create a color scheme from a single seed color based on the Material 3 color system. Override the brightness property of ColorScheme.fromSeed to create a dark color scheme. To create a high-contrast color scheme, set contrastLevel to 1.0.

This example demonstrates how to create a color scheme similar to ColorScheme.highContrastDark using the ColorScheme.fromSeed constructor:
link 
colorScheme: ColorScheme.fromSeed(
  seedColor: const Color(0xffefb7ff),
  brightness: Brightness.dark,
).copyWith(
  primaryContainer: const Color(0xffefb7ff),
  onPrimaryContainer: Colors.black,
  secondaryContainer: const Color(0xff66fff9),
  onSecondaryContainer: Colors.black,
  error: const Color(0xff9b374d),
  onError: Colors.white,
),
