Properties

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

image → Image

Image to be cropped

final

imgOffset → Offset

The offset from SimpleImageCropper

final

onRegionSelected → (dynamic Function(Region)?)

The callback from SimpleImageCropper

final

region → Region

Get the region from corner grabber

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scaleRatio → double

The ratio from SimpleImageCropper

final

semanticsBuilder → SemanticsBuilderCallback?

Returns a function that builds semantic information for the picture drawn by this painter.

no setter, override

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

dispose() → void

Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).

inherited

globalToLocalPt(Offset global) → Offset

Convert global position global to local position

hitTest(Offset position) → bool?

Called whenever a hit test is being performed on an object that is using this custom paint delegate.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

onPanDown(Offset globalPt) → void

onPanEnd() → void

onPanUpdate(Offset globalPt) → void

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 are notified when the object changes.

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).

override

shouldRepaint(covariant ImageEditor 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.
