DashedPainter class
DashedPainter is a custom painter that draws a dashed line around the
child
widget. The strokeWidth property defines the width of the dashed
border and color determines the stroke paint color. CircularIntervalList
is populated with the dashPattern to render the appropriate pattern. The
radius property is taken into account only if the borderType is
BorderType.RRect. A customPath can be passed in as a parameter if you
want to draw a custom shaped border.

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 originalSize) → 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 DashedPainter 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.

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