FluentPolarGridPainter class

Paints the polar grid: the rings and the spokes.

Kept apart from the series layer because the grid is static across every hover and legend change, so it repaints only when the layout itself changes.

Constructors

FluentPolarGridPainter({required FluentPolarLayout layout, required FluentPolarShape shape, required Color gridColor, required double gridWidth, required double innerOpacity, required double outerOpacity})
Creates a grid painter.

Properties

gridColor → Color
Stroke colour of every grid line.
final
gridWidth → double
Stroke width of every grid line.
final
hashCode → int
The hash code for this object.
no setterinherited
innerOpacity → double
Opacity of an inner ring and of every spoke.
final
layout → FluentPolarLayout
The solved layout.
final
outerOpacity → double
Opacity of the outermost ring.
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
shape → FluentPolarShape
Whether the rings are circles or polygons.
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 FluentPolarGridPainter 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.
