Glitch class

A digital glitch effect painter that creates cyberpunk-style glitch artifacts.

This effect simulates digital corruption with RGB channel splitting, scanlines, pixel displacement, and random artifacts. Perfect for cyberpunk, retro, or glitch art aesthetics.

Usage

CustomPaint(
  painter: Glitch(
    colors: [Colors.cyan, Colors.magenta],
    intensity: 0.8,
    speed: 1.5,
    touchPosition: () => Offset(0.5, 0.5),
  ),
)

Constructors

Glitch({required List<Color> colors, double intensity = 0.8, double speed = 1.0, GlitchType glitchType = GlitchType.digital, Offset touchPosition()?, double deviceDensity = 1.0}): Creates a digital glitch effect painter.

Properties

colors → List<Color>: Colors for the glitch effect.
final
deviceDensity → double: The device density.
finalinherited
glitchType → GlitchType: Type of glitch effect to apply.
final
hashCode → int: The hash code for this object.
no setterinherited
intensity → double: Glitch intensity (0.0 to 1.0).
final
isShaderLoaded → bool: Whether the shader has been loaded and compiled.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
semanticsBuilder → SemanticsBuilderCallback?: Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited
shaderPath → String: Path to the GLSL fragment shader file.
finalinherited
speed → double: Animation speed (0.0 to 2.0).
final
touchPosition → Offset Function()?: Touch/mouse position for interaction (normalized 0.0-1.0).
final
uniforms → Map<String, dynamic>: Map of uniform values to pass to the shader.

Methods

addListener(VoidCallback listener) → void: Register a closure to be notified when it is time to repaint.
inherited
dispose() → void: Disposes of shader resources.
inherited
getTouchPosition() → Offset: Gets the current touch position in normalized coordinates (0.0 to 1.0).
override
hitTest(Offset position) → bool?: Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
loadShader() → Future<void>: Loads and compiles the GLSL shader.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void: Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
override
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
setCustomUniforms(FragmentShader shader, int startIndex) → void: Sets custom uniforms specific to this shader effect.
override
shouldRebuildSemantics(covariant CustomPainter oldDelegate) → bool: Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant Glitch oldDelegate) → bool: Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
override
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
