Creates a coordinate system painter.

Properties

coordinatesMap → Map<E, Coordinates<E>>
Map containing all coordinates data.
final
coordinateSystemOrigin → Offset
Coordinate system origin offset value.
final
divisions → int
The division value of y-axis.
final
fillWidth → bool
Align the first and last points of the chart with both ends.
final
getXAxisTickLineWidth → GetXAxisTickLineWidth
Get X-axis tick line width from the length of SlidableLineChart.xAxis.
final
getYAxisTickLineHeight → GetYAxisTickLineHeight
Get Y-axis tick line height from the length of _yAxis.
final
hashCode → int
The hash code for this object.
no setterinherited
max → int
The maximum value that the user can slide to.
final
maxOffsetValueOnYAxisSlidingArea → double
Maximum offset on the Y-axis sliding area.
final
min → int
The minimum value that the user can slide to.
final
onDrawCheckOrClose → OnDrawIndicator?
Called when the user slides coordinate, the return value determines the indicator type.
final
onlyRenderEvenAxisLabel → bool
Whether the y-axis label renders only even items.
final
otherCoordsAnimationCtrl → AnimationController?
Animation controller with other line chart.
final
positionPadding → EdgeInsets
To ensure that the tap area of ​​the coordinate point can respond to touch events even when it is at the edge, the chart itself should be padded inwards with the maximum value of the zoomed radius and the SlidableLineChart.coordinateSystemOrigin.
final
reversed → bool
Whether the coordinate system is reversed.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticsBuilder → SemanticsBuilderCallback?
Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited
slidableCoordinateType → E?
The type of coordinates the user can slide.
final
slidableCoordsAnimationCtrl → AnimationController?
Animation controller with slidable line chart.
final
slidableLineChartThemeData → SlidableLineChartThemeData<E>?
Defines the configuration of the overall visual SlidableLineChartThemeData for a SlidableLineChart.
final
triggerClear → bool
The flag that triggers the cleanup animation.
final
xAxis → List<String>
Labels displayed on the x-axis.
final
yAxis → List<int>
Text display on Y-axis.
final

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 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 CoordinateSystemPainter<E> 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.
