Question

flutter AppBarTheme 亮度已弃用，推荐使用 colorScheme 什么是 colorScheme 以及如何实现它

Answer 1

ColorScheme 是一组基于 Material 颜色系统的颜色，可用于配置大多数组件的颜色属性。

你可以这样使用它

  static const ColorScheme colorSchemeLight = ColorScheme(
    primary: primaryColor,
    secondary: accentColor,
    surface: background,
    background: background,
    brightness: Brightness.light,
    error: failurRed,
    onBackground: Colors.black,
    onError: Colors.white,
    onPrimary: Colors.white,
    onSecondary: Colors.white,
    onSurface: Colors.black,
    primaryContainer: primaryColor,
    secondaryContainer: accentColor,
  );
    mainTheme = ThemeData(
            appBarTheme: appBarTheme,
            brightness: Brightness.light,
            primaryColor: primaryColor,
            colorScheme: colorSchemeLight,
            textTheme: viatoTextTheme,
            backgroundColor: background,
            scaffoldBackgroundColor: background);
