ShaderTransition class sealed

A shader-backed screen transition.

Create one with a named constructor — ShaderTransition.diamond(), .circle(), .wipe(), .clock(), .polygon(), .dissolve(), .fade(), or .bars():

ShaderPageRoute(
  page: const NextPage(),
  transition: const ShaderTransition.circle(origin: Alignment.bottomRight),
)

Each one returns the matching concrete subtype of this sealed hierarchy, which you can also construct directly:

• DiamondTransition — a sweeping grid of diamond cells.
• CircleTransition — a circular iris reveal from CircleTransition.origin.
• WipeTransition — a straight feathered edge in a SweepDirection.
• ClockTransition — a radial sweep, optionally multi-sector.
• PolygonTransition — a regular-polygon iris.
• DissolveTransition — a noise-grain dissolve.
• FadeShaderTransition — a uniform cross-fade.
• BarsTransition — a venetian-blind reveal.

Every transition shares duration, an optional cover, and an invert flag. Pass one to ShaderPageRoute, ShaderTransitions factories, ShaderTransitionBuilders.create, ShaderPageTransitionsBuilder, or ShaderTransitionSwitcher.
