Shadows

The DropShadow image filter is equivalent to its SVG counterpart. It creates a filter that draws a drop shadow under the input content. A shadowOnly property renders the drop shadow, excluding the input content. It can also render an inner shadow via the inner property.

If you want to render inner shadows to a rounded rectangle, box shadows are much faster.

Name	Type	Description
dx	number	The X offset of the shadow.
dy	number	The Y offset of the shadow.
blur	number	The blur radius for the shadow
color	Color	The color of the drop shadow
inner?	boolean	Shadows are drawn within the input content
shadowOnly?	boolean	If true, the result does not include the input content
children?	ImageFilter	Optional image filter to be applied first

Drop Shadow

The example below creates two drop shadows. It is equivalent to the following CSS notation.

.paint {
  filter: drop-shadow(12px 12px 25px #93b8c4) drop-shadow(-12px -12px 25px #c7f8ff);
}

import {
  Shadow,
  Fill,
  RoundedRect,
  Canvas
} from "@shopify/react-native-skia";

const Neumorphism = () => {
  return (
    <Canvas style={{ width: 256, height: 256 }}>
      <Fill color="lightblue" />
      <RoundedRect x={32} y={32} width={192} height={192} r={32} color="lightblue">
        <Shadow dx={12} dy={12} blur={25} color="#93b8c4" />
        <Shadow dx={-12} dy={-12} blur={25} color="#c7f8ff" />
      </RoundedRect>
    </Canvas>
  );
};

Result

Inner Shadow

import {
  Shadow,
  Fill,
  RoundedRect,
  Canvas
} from "@shopify/react-native-skia";

const Neumorphism = () => {
  return (
    <Canvas style={{ width: 256, height: 256 }}>
      <Fill color="lightblue" />
      <RoundedRect x={32} y={32} width={192} height={192} r={32} color="lightblue">
        <Shadow dx={12} dy={12} blur={25} color="#93b8c4" inner />
        <Shadow dx={-12} dy={-12} blur={25} color="#c7f8ff" inner />
      </RoundedRect>
    </Canvas>
  );
};
