Constructors

VectorBase({required VectorImagePainter painter, required double baseImageSize, required double requestSize})

Both painter and baseImagesSize are required painter (VectorImagePainter) : the Painter that helps use draw the Vector baseImageSize (double) : the size of the original image requestSize (double) : the wanted size

Properties

child → Widget?

The widget below this widget in the tree.

final, inherited

foregroundPainter → CustomPainter?

The painter that paints after the children.

final, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isComplex → bool

Whether the painting is complex enough to benefit from caching.

final, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

painter → CustomPainter?

The painter that paints before the children.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → Size

Methods

createElement() → SingleChildRenderObjectElement

RenderObjectWidgets always inflate to a RenderObjectElement subclass.

inherited

createRenderObject(BuildContext context) → RenderCustomPaint

Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.

inherited

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

didUnmountRenderObject(covariant RenderCustomPaint renderObject) → void

A render object previously associated with this widget has been removed from the tree. The given RenderObject will be of the same type as returned by this object's createRenderObject.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

updateRenderObject(BuildContext context, covariant RenderCustomPaint renderObject) → void

Copies the configuration described by this RenderObjectWidget to the given RenderObject, which will be of the same type as returned by this object's createRenderObject.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
