ExtendedImageCropLayerPainter class

This class extends CustomPainter and is responsible for managing the state of the crop layer, including rotation, crop area dimensions, and visual attributes like line color, corner size, and mask color.

Properties

cornerColor → Color
The color of the corner markers
final
cornerSize → Size

final
cropLayerPainter → EditorCropLayerPainter
Custom painter to handle crop layer painting
final
cropRect → Rect
The rectangle defining the crop area
final
hashCode → int
The hash code for this object.
no setterinherited
lineColor → Color
The color of the crop lines
final
lineHeight → double
The thickness of the crop lines
final
maskColor → Color
The color of the mask outside the crop area
final
pointerDown → bool
Indicates whether the pointer is down (user interaction in progress)
final
rotateRadians → double
The rotation angle of the crop area (in radians)
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.

Methods

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
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.
inherited

Operators

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