GeoShape class

A CustomPainter that renders geographic shapes from GeoJSON data.

GeoShape uses a Projection to transform geographic coordinates into screen coordinates and renders them as paths.

Constructors

GeoShape({required Projection projection, required dynamic geoJson, Color? fillColor, Color? strokeColor, double strokeWidth = 1.0, bool antiAlias = true})
Creates a GeoShape painter.

Properties

antiAlias → bool
Whether to enable anti-aliasing.
final
fillColor → Color?
The color to use for filling shapes.
final
geoJson → dynamic
The GeoJSON data to render.
final
hashCode → int
The hash code for this object.
no setterinherited
projection → Projection
The projection to use for coordinate transformation.
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
strokeColor → Color?
The color to use for stroking shapes.
final
strokeWidth → double
The stroke width for shape outlines.

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 GeoShape 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.
