DissolveEffect class

A shader-based dissolve effect that disintegrates a child widget.

Uses layered value noise to create an organic dissolve pattern with bright white-orange spark edges at the dissolution boundary. This effect requires a child widget to be provided in GKWidget.

The progress value drives the dissolve: 0.0 is fully visible, 1.0 is fully dissolved. You can animate this via the GKController or pass a fixed value.

{@tool snippet}

GKWidget(
  effect: DissolveEffect(
    progress: 0.5,
    noiseScale: 4.0,
    edgeSoftness: 0.1,
  ),
  child: Image.asset('assets/photo.png'),
)
