Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
drawInitailPoint(Canvas canvas, Size size) → void
desenha o ponto inicial de cruzamento os dois eixos
desenha uma linha que liga dois pontos
drawPoint(Canvas canvas, Size size, List<List<int>> values, List<List<Offset>> xPoints, List<List<Offset>> yPoints, List<int> yValues) → void
vai desenhar o ponto de encontro entre os eixos x e y
drawXAxis(Canvas canvas, Size size) → List<int>
designs the x axis canvas: is the object we are going to draw size: is the size of the area where we are going to draw returns an array containing: firs two are coordinates where we'll start building the markers of this axis and the last one are real points in the x axis
drawXMarkers(Canvas canvas, Size size, double startX) → void
desenha marcadores no eixo X
drawYAxis(Canvas canvas, Size size) → List<int>
designs the y axis canvas: is the object we are going to draw size: is the size of the area where we are going to draw the function return an int value in where will start building the markers of this axis
drawYMarkers(Canvas canvas, Size size, double startX) → void
desenha marcadores no eixo Y
getCustomPaint(Color color, double strokeWidth, PaintingStyle style) → dynamic
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
size: é o tamanho da area onde vamos desenhar canvas: é o objeto que vamos desenhar paint: é o objeto que contém as propriedades do que desejamos desenhar: cor, espessura da linha, etc
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
setText(String text, Canvas canvas, dynamic size, Offset location, String axis) → dynamic
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
toString() → String
A string representation of this object.
inherited

Operators

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