BubblePainter class

Custom painter that renders animated bubbles with realistic visual effects.

Creates bubbles with radial gradients and highlight reflections to simulate real bubble appearance with light refraction and transparency.

Constructors

BubblePainter({required List<Bubble> bubbles, required Color bubbleColor, required int bubbleOpacity, required Color minCircleBubbleColor}): Creates a bubble painter with the specified visual properties.

bubbleColor → Color: Base color for bubble rendering
final
bubbleOpacity → int: Opacity level for bubbles (0-255 range)
final
bubbles → List<Bubble>: List of bubbles to render with their current positions
final
hashCode → int: The hash code for this object.
no setterinherited
minCircleBubbleColor → Color: Color for the highlight reflection inside each bubble
final
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

addListener(VoidCallback listener) → void: Register a closure to be notified when it is time to repaint.
inherited
hitTest(Offset position) → bool?: Called whenever a hit test is being performed on an object that is using this custom paint delegate.
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
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 CustomPainter oldDelegate) → bool: Always repaint since bubbles are constantly moving
override
toString() → String: A string representation of this object.
