PolygonTransition class final

A regular-polygon iris reveal from origin. A high sides count approximates CircleTransition.

const PolygonTransition(sides: 3)            // triangle iris
const PolygonTransition(sides: 6, rotation: 0.5)

Constructors

PolygonTransition({Alignment origin = Alignment.center, int sides = 6, double feather = 2.0, double rotation = 0.0, Duration duration = const Duration(milliseconds: 700), TransitionCover? cover, bool invert = false})
Creates a polygon iris transition.

Properties

cover → TransitionCover?
Optional flat-color cover for a cinematic fade-through transition. null (default) lets the outgoing page show through — a classic mask reveal.
finalinherited
duration → Duration
Total animation time, used unchanged for both push and pop.
finalinherited
feather → double
Edge softness of the polygon outline, in logical pixels.
final
hashCode → int
The hash code for this object.
no setterinherited
invert → bool
Reverses the reveal direction of the effect. For CircleTransition this turns the expanding iris into a contracting one; for directional transitions it flips which side reveals first.
finalinherited
origin → Alignment
The point the polygon iris emanates from.
final
rotation → double
Polygon orientation, in radians.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shaderKey → String
The ShaderRegistry key (and .frag basename) backing this transition.
no setteroverride
sides → int
Polygon side count. Clamped to ≥ 3; large values look circular.
