ComposeShadowsPlus provides two custom shadow Modifiers: RSBlurShadow and SoftLayerShadow.

ComposeShadowsPlus common params:

Param Description
radius The shadow radius.
color The shadow color.
shape The shadow shape.
spread The shadow positive or negative spread.
offset The shadow offset.
isAlphaContentClip Indicates if shadow is clipped for alpha content.

ShadowsPlusDefaults contains default values of custom shadows.

You can use Modifier.shadowsPlus(...) to set the custom shadows with the ShadowsPlusType enum.


RSBlurShadow uses RenderScript and ScriptIntrinsicBlur to blur the shadow content to simulate the shadow.

RSBlurShadow more params:

Param Description
alignRadius The exponential align radius indicator.

To apply RSBlurShadow use Modifier.rsBlurShadow(...).


SoftLayerShadow uses NativePaint.setShadowLayer(...) to apply the native shadow layer to the shadow content.

To render SoftLayerShadow, Android devices with API < 28(P), need to use View.LAYER_TYPE_SOFTWARE. It's recommended to use SoftLayerShadowContainer to handle this automatically.

To apply SoftLayerShadow use Modifier.softLayerShadow(...).


To use clipped shadow for alpha content with elevation(Android Compose .shadow(...)), wrap your content with AlphaContentElevationShadow.

If you want the clipped elevation as Modifier use shadow-gadgets library.
