VectorBase class abstract
The base definition of a Vector Widget.
- Inheritance
- Implementers
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

finalinherited
- foregroundPainter → CustomPainter?
-
The painter that paints after the children.
finalinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isComplex → bool
-
Whether the painting is complex enough to benefit from caching.
finalinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- painter → CustomPainter?
-
The painter that paints before the children.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- size → Size
-
The size that this CustomPaint should aim for, given the layout
constraints, if there is no child.
finalinherited

-
Whether the raster cache should be told that this painting is likely
to change in the next frame.

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 -
This method is called when a RenderObject that was previously
associated with this widget is removed from the render tree.
The provided RenderObject will be of the same type as the one created by
this widget's createRenderObject method.
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, int wrapWidth = 65}) → 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.
