DropShadowPainter

DropShadowPainter(shape: Shape, shadow: Shadow)

Create a DropShadowPainter with the specified shape and shadow. It is preferred to obtain an instance of the DropShadowPainter through a ShadowContext instance instead, as the underlying shadow dependencies can be shared across multiple DropShadowPainter instances. However, creating an instance through this constructor will not share resources with any other DropShadowPainter.

open val intrinsicSize: Size

Return the intrinsic size of the Painter. If the there is no intrinsic size (i.e. filling bounds with an arbitrary color) return Size.Unspecified. If there is no intrinsic size in a single dimension, return Size with Float.NaN in the desired dimension. If a Painter does not have an intrinsic size, it will always draw within the full bounds of the destination
