)

Creates a group of parameters that represent how a drop shadow or inner shadow should be rendered.

Parameters


radius	The blur radius of the shadow
brush	Brush used to blend against a mask defined by the shadow geometry
spread	Optional parameter to grow the shadow geometry by
offset	Optional parameter to offset the shadow within the geometry bounds
alpha	Optional opacity of the shadow
blendMode	Optional blending algorithm used by the shadow

constructor(
    radius: Dp,
    color: Color = Color.Black,
    spread: Dp = 0.dp,
    offset: DpOffset = DpOffset.Zero,

    brush = null,
    alpha = alpha,
    blendMode = blendMode,
)

Creates a group of parameters that represent how a drop shadow or inner shadow should be rendered.

Parameters


radius	The blur radius of the shadow
color	The color of the shadow. If `Color.Unspecified` is provided, `Color.Black` will be used as a default.
spread	Optional parameter to grow the shadow geometry by
offset	Optional parameter to offset the shadow within the geometry bounds
alpha	Optional opacity of the shadow
blendMode	Optional blending algorithm used by the shadow

Properties

Common

val color: Color

Color of the shadow. If Color.Unspecified is provided, Color.Black will be used as a default. This color is only used if brush is null.

Common

val brush: Brush?

Optional brush to render the shadow with.

Common

val alpha: Float

Opacity of the shadow

Common

class Shadow(
    @Stable val color: Color = Color(0xFF000000),
    @Stable val offset: Offset = Offset.Zero,
    @Stable val blurRadius: Float = 0.0f,
)

A single shadow.

Functions

        color: Color = this.color,
        offset: Offset = this.offset,
        blurRadius: Float = this.blurRadius,
    ): Shadow

Companion Object

Properties

Common

val None = Shadow()

Constant for no shadow.
