我正在关注材料设计组件，在底部，每个组件都有一个主题部分。

这是主题数据代码，

final ThemeData base = ThemeData.light();
return base.copyWith(
  colorScheme: _shrineColorScheme, 
  toggleableActiveColor: shrinePink400,
  accentColor: shrineBrown900,
  primaryColor: shrinePink100,  //defines primary
  buttonColor: shrinePink100,
  scaffoldBackgroundColor: shrineBackgroundWhite,
  cardColor: shrineBackgroundWhite,
  textSelectionColor: shrinePink100,
  errorColor: shrineErrorRed,
  primaryIconTheme: _customIconTheme(base.iconTheme),
  textTheme: _buildShrineTextTheme(base.textTheme),
  primaryTextTheme: _buildShrineTextTheme(base.primaryTextTheme),
  accentTextTheme: _buildShrineTextTheme(base.accentTextTheme),
  iconTheme: _customIconTheme(base.iconTheme),
);
}

这是ColorScheme的定义，

const ColorScheme _shrineColorScheme = ColorScheme(
 primary: shrinePink400,  //defines primary
 primaryVariant: shrineBrown900,
 secondary: shrinePink50,
 secondaryVariant: shrineBrown900,
 surface: shrineSurfaceWhite,
 background: shrineBackgroundWhite,
 error: shrineErrorRed,
 onPrimary: shrineBrown900,
 onSecondary: shrineBrown900,
 onSurface: shrineBrown900,
 onBackground: shrineBrown900,
 onError: shrineSurfaceWhite,
 brightness: Brightness.light,
);

这里原色 …
