getShadows static method

List<BoxShadow> getShadows(
  1. bool isDark, {
  2. bool isOutlined = false,
  3. ContentDesignStyle? designStyle,
  4. Color? accentColor,
})

Returns layered upward shadows for the sheet surface.

When accentColor is provided the elevation includes a tinted glow in that color; otherwise a neutral ambient elevation is used.

Implementation

static List<BoxShadow> getShadows(
  bool isDark, {
  bool isOutlined = false,
  ContentDesignStyle? designStyle,
  Color? accentColor,
}) {
  final style =
      designStyle ??
      (isOutlined ? ContentDesignStyle.outlined : ContentDesignStyle.solid);

  // Sheets sit at the bottom edge, so the elevation rises upward.
  const up = Offset(0, -1);

  if (style == ContentDesignStyle.minimal) return SpShadows.flat;
  if (style == ContentDesignStyle.neon) {
    return accentColor != null
        ? SpShadows.neon(color: accentColor, direction: up)
        : SpShadows.ambient(isDark: isDark, direction: up);
  }

  final level = switch (style) {
    ContentDesignStyle.colorHeader || ContentDesignStyle.solid => 1.0,
    ContentDesignStyle.tonal || ContentDesignStyle.glass => 0.85,
    ContentDesignStyle.outlined || ContentDesignStyle.leftAccent => 0.7,
    ContentDesignStyle.minimal || ContentDesignStyle.neon => 1.0,
  };

  if (accentColor != null) {
    return SpShadows.glow(
      color: accentColor,
      isDark: isDark,
      level: level,
      direction: up,
    );
  }
  return SpShadows.ambient(isDark: isDark, level: level, direction: up);
