BoxDecoration constructor
- {Color? color,
- DecorationImage? image,
- BoxBorder? border,
- BorderRadiusGeometry? borderRadius,
- List<
BoxShadow> ? boxShadow, - Gradient? gradient,
- BlendMode? backgroundBlendMode,
- BoxShape shape = BoxShape.rectangle}
Creates a box decoration.
- If color is null, this decoration does not paint a background color.
- If image is null, this decoration does not paint a background image.
- If border is null, this decoration does not paint a border.
- If borderRadius is null, this decoration uses more efficient background painting commands. The borderRadius argument must be null if shape is BoxShape.circle.
- If boxShadow is null, this decoration does not paint a shadow.
- If gradient is null, this decoration does not paint gradients.
- If backgroundBlendMode is null, this decoration paints with BlendMode.srcOver
