GradientFlowEffect class - gradient_flow_effect library

GradientFlowEffect class

An animation effect that creates a flowing gradient along the connection.

The gradient smoothly flows along the path, creating an elegant visual effect that shows direction and movement.

Example:

connection.animationEffect = GradientFlowEffect(
  colors: [Colors.blue, Colors.cyan, Colors.blue],
  speed: 1.0,
);

Constructors

GradientFlowEffect({List<Color>? colors, int speed = 1, double gradientLength = 0.25, double connectionOpacity = 1.0}): Creates a gradient flow animation effect.

colors → List<Color>?: Colors for the gradient. If null, creates a gradient using the connection color.
final
connectionOpacity → double: Opacity of the base connection outside the gradient (0.0 to 1.0) 1.0 = full opacity (no fading), 0.0 = invisible
final
gradientLength → double: Length of the gradient.
final
hashCode → int: The hash code for this object.
no setterinherited
isBuiltIn → bool: Available on ConnectionEffect, provided by the ConnectionEffectExtension extension
Check if this is a built-in connection effect
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
speed → int: Number of complete cycles per animation period (integer for seamless looping)
final

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Path path, Paint basePaint, double animationValue) → void: Paints the animated connection effect on the canvas.
override
toString() → String: A string representation of this object.
