Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
asBackground(
{Widget? child}) → CustomPaint -
inherited
-
asForeground(
{Widget? child}) → CustomPaint -
inherited
-
delegatePaint(
Canvas canvas, Size size) → void -
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
-
givePainterCall(
ContextAccessor? ctxAccessor) → PainterCall? -
该方法使得绘图方法只依赖一次 ctx 并缓存以来的计算数据，比如大小位置信息等。
inherited
-
hitTest(
Offset position) → bool? -
Called whenever a hit test is being performed on an object that is using
this custom paint delegate.
inherited
-
isBlank(
int x, int y) → bool -
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
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.inherited -
paintContext(
ContextAccessor? ctxAccessor, Canvas ctxCanvas, Size ctxSize) → void -
该方法使得绘图方法次次依赖实时的 ctx 数据，可能造成性能影响
inherited
-
paintPixel(
String instructStr, int xIndex, int yIndex, Canvas ctxCanvas, Rect paintRect) → void -
inherited
-
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).
inherited
-
shouldRepaint(
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
-
toSizedWidget(
[Widget? child]) → SizedBox -
inherited
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
