ShapeMorphPainter class
Paints a ShapeMorphGeometry at the clock's current value: still chrome
with its ink lerping, pairs bending point-for-point with theirs, exits and
enters trimming under the StrokeTaper laws. Drive it with any
Animation<double> — an IconicShapeMorph for the drop-in case, or your
own controller when the morph is one voice inside a larger stateful glyph.

final
- chromeColor → Color
-
Ink of the STILL chrome at the start / end. Defaults follow color /
colorEnd — one-colour icons need nothing extra.

- chromeColorEnd → Color
-
final
- color → Color
-
Ink of the MORPHING shapes (pairs + exits + enters) at the start / end.

final
- geometry → ShapeMorphGeometry
-
final
- hashCode → int
-
The hash code for this object.

- runtimeType → Type
-
A representation of the runtime type of the object.

- semanticsBuilder → SemanticsBuilderCallback?
-
Returns a function that builds semantic information for the picture drawn
by this painter.

-
Timing knobs are read from the same spec that built geometry.

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
sizeargument.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 ShapeMorphPainter old) → 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.
